The Short Answer
A broken ankle is not one injury. It's a spectrum — from a hairline crack in the fibula that heals in a boot, to a fracture-dislocation with three broken bones and torn ligaments that needs surgery within days.
The single question that drives everything is: is the ankle stable?
If the talus — the bone your leg sits on top of — is still centered under the tibia and stays there when you put weight on it, most of these fractures do beautifully without surgery. If the talus has shifted even a couple of millimeters, that's a different injury with a different plan, because a talus that sits off-center wears the cartilage out over years.
That distinction isn't always obvious on the X-ray taken in the emergency room while your ankle is swollen and you're in pain. It's the reason I want to see ankle fractures in the office within a week, even the ones that "looked fine" at the ER.
Let me walk you through the whole thing the way I do in clinic.

How Common Is This, and Who Gets It?
Ankle fractures are among the most common lower limb fractures, with reported incidence between 42 and 187 per 100,000 people per year, and the numbers have been climbing over the past few decades.
There's a bimodal pattern — two distinct peaks:
- Young adults, more often men, usually from sports: soccer, basketball, football. Higher-energy injuries.
- Older adults, more often women, usually from a simple fall or a twist stepping off a curb. Lower-energy injuries, but often in weaker bone.
About 58% of ankle fractures come from a simple fall or twisting injury, and those skew toward older women. Sports injuries — soccer being the classic — skew toward young men.
And the volume is going up. With an aging population, ankle fractures in the elderly are projected to increase substantially.
The breakdown by pattern: roughly 70% are isolated malleolar fractures (most often the lateral malleolus alone), 23% are bimalleolar, and 7% are trimalleolar.

Anatomy in Plain English
Your ankle is a mortise and tenon joint — like a woodworking joint. Three bones:
- Tibia — the shinbone. Its inner bump at the ankle is the medial malleolus. The back lip is the posterior malleolus.
- Fibula — the smaller outer bone. Its bump is the lateral malleolus.
- Talus — the block-shaped bone that sits in the socket formed by the other two.
Holding it together:
- Deltoid ligament on the inside — thick, strong, and critical for stability.
- Lateral ligaments on the outside — the ones you tear in a routine ankle sprain.
- Syndesmosis — the tough fibrous connection between the tibia and fibula just above the joint. This is the "high ankle" structure.
Here's the concept that matters most: the talus must stay perfectly centered. The joint tolerates almost no shift. Even a millimeter or two of lateral talar shift dramatically reduces the contact area between cartilage surfaces, which concentrates pressure on a smaller patch of cartilage. Do that for years and you get arthritis.
That's the whole reason surgery exists for these injuries. Not to make the X-ray pretty. To keep the talus centered so the cartilage survives.

Why This Happens
Most ankle fractures are rotational — the foot gets planted and the body rotates over it. A cleat catches in turf. A foot lands awkwardly on someone else's shoe. A step off a curb in the dark.
The specific bones that break depend on two things: where your foot was positioned and which direction the force went. That's the basis of the Lauge-Hansen classification, which categorizes injuries by foot position and deforming force at the time of injury — supination-external rotation, supination-adduction, pronation-external rotation, pronation-abduction.
Why does an eighty-year-old classification matter to you? Because these injuries follow predictable patterns. If I see a certain fibula fracture, I know which ligaments are probably torn even though ligaments don't show up on X-ray. Identification of the fracture pattern allows diagnosis of otherwise occult ligamentous injuries. That's how I know to look harder at your deltoid or your syndesmosis.
Risk factors:
- Prior ankle sprains or chronic ankle instability
- Osteoporosis or low bone density
- Higher BMI
- Diabetes (both for getting the fracture and, importantly, for complications afterward)
- Cutting and pivoting sports
- Poor lighting, uneven ground, and — genuinely — stairs and curbs

Types of Ankle Fracture
Type | What's broken | Typical stability | Usual treatment |
Isolated lateral malleolus (Weber A) | Fibula below the syndesmosis | Usually stable | Boot, early weight-bearing |
Isolated lateral malleolus (Weber B) | Fibula at the syndesmosis | Depends on the deltoid — stable or unstable | Boot if stable; surgery if talus shifts |
Isolated lateral malleolus (Weber C) | Fibula above the syndesmosis | Usually unstable, syndesmosis usually injured | Surgery |
Isolated medial malleolus | Inner tibia bump | Variable | Depends on displacement and pattern |
Bimalleolar | Medial + lateral | Unstable | Surgery |
Bimalleolar-equivalent | Fibula + torn deltoid | Unstable | Surgery |
Trimalleolar | Medial + lateral + posterior | Unstable | Surgery |
Fracture-dislocation | Any of the above with the talus out of the socket | Very unstable | Urgent reduction, then surgery |
Pilon fracture | Weight-bearing roof of the tibia, crushed | Severe | Staged surgery, different injury entirely |
Maisonneuve | Fibula fracture up near the knee + syndesmosis | Unstable, easily missed | Surgery |
The Weber system — which I use in conversation constantly — groups fibula fractures by their relationship to the syndesmosis: A below, B at the level, C above. It's simple and it maps roughly onto how likely the syndesmosis is to be injured.
Bimalleolar-equivalent deserves a special mention because it's the one patients don't understand. Your X-ray shows one broken bone — the fibula. But the deltoid ligament on the inside is torn, which means functionally you have a two-sided injury. On paper it's a one-bone fracture. Biomechanically it's a bimalleolar. These are inherently unstable and typically treated surgically.
The Maisonneuve fracture is the one that gets missed. You twist your ankle, your ankle hurts, and nobody X-rays your knee — where the fibula actually broke. If the inside of your ankle is tender and the X-ray shows no fibula fracture at the ankle, I squeeze the whole length of your fibula up to the knee. Always.

Symptoms: What You'll Notice
Immediately:
- A crack or pop, often heard or felt
- Immediate severe pain
- Inability to bear weight (though not always — some people walk on these)
- Rapid swelling
- Bruising that appears over hours to days and often tracks into the foot and toes
- Visible deformity if the ankle is dislocated
Warning signs that mean go to the ER now, not tomorrow:
- Obvious deformity — the foot is pointing the wrong way. This needs urgent reduction.
- Bone through the skin or any open wound over the fracture — this is an open fracture and it is a surgical emergency.
- Numbness or the foot turning pale or cold
- Skin that is tented white and stretched over a bone edge — the skin is about to die
- Rapidly increasing, unrelenting pain out of proportion, particularly with a tense, hard leg
A useful clinical point: being able to walk does not mean it isn't broken. I see patients weekly who walked on a fractured ankle for days. The Ottawa ankle rules exist precisely because you can't tell a bad sprain from a fracture by pain level alone.

How I Diagnose It
The exam. I'm looking at soft tissues first — swelling, blisters, abrasions, skin condition — because that determines when surgery can happen. Then:
- Where exactly is the tenderness? Medial tenderness with a lateral fracture raises suspicion for a deltoid injury.
- Squeeze the whole fibula to the knee — looking for Maisonneuve.
- Palpate the syndesmosis just above the joint line.
- Palpate the base of the fifth metatarsal and the navicular — these get injured together and get missed together. See Jones Fracture.
- Check the midfoot — a Lisfranc injury can accompany or masquerade as an ankle injury.
- Neurovascular exam — pulses, sensation, motor function.
X-rays: three views, and one of them is the one that matters.
- AP — general alignment
- Lateral — the posterior malleolus and any talar shift front-to-back
- Mortise — the ankle rotated inward about 15°, giving a clean look at the joint space
On the mortise view I measure the medial clear space — the gap between the medial malleolus and the talus. If it's widened, the talus has shifted and the deltoid is torn. That measurement changes the treatment plan more than almost anything else on the study.
The weight-bearing X-ray — the most useful test most patients never get.
Here's the problem with the ER X-ray: you were lying on a stretcher. Gravity wasn't loading the joint. An unstable ankle can look perfectly aligned when it isn't being asked to do anything.
Current expert consensus is explicit on this point: for stable, non- or minimally displaced unimalleolar fractures being considered for nonoperative treatment, stability should be verified by bilateral, weight-bearing radiography.
Practically, this means standing on it — which patients find alarming and which is safe under supervision — and comparing to the other side. If the talus stays centered under load, it's stable and you're going in a boot. If it shifts, you need surgery. This single test is the difference between correct treatment and a slowly failing ankle.
Some surgeons use a gravity stress view instead — lying on your side with the leg hanging. It's easier when patients are in too much pain to stand.
CT scan — when I want to see the architecture.
I order CT for:
- Posterior malleolus fractures — to see how big the fragment is and whether it involves the joint surface. This directly determines whether I fix it.
- Suspected articular impaction — particularly in supination-adduction patterns, where the medial tibial plafond and talar body can be crushed. Articular impaction is present in 73% of these injuries. You will miss it on plain films.
- Pilon fractures — always.
- Syndesmotic malreduction concerns
- Preoperative planning in comminuted patterns
MRI — occasionally.
Not routine. Useful when I suspect a deltoid or syndesmotic injury that isn't clear otherwise, when I'm worried about an osteochondral lesion of the talus, or when there's suspicion of an occult stress fracture rather than an acute break. It's also the study for a suspected peroneal tendon injury alongside the fracture.

Nonoperative Treatment: Who Doesn't Need Surgery
A lot of people. This is worth saying loudly, because patients arrive convinced that "broken" means "surgery."
The criteria: stable, non-displaced or minimally displaced unimalleolar fractures — AO 44A and 44B patterns — can be treated non-operatively with an early return to function, provided stability is confirmed on weight-bearing films.
How it's done:
- A walking boot (CAM boot) in most cases, sometimes a cast initially if swelling and pain are severe
- Weight-bearing as tolerated in most stable patterns
- Boot for roughly 6 weeks, with X-rays at intervals to confirm nothing shifts
- Transition to a supportive shoe with an ankle brace
- Physical therapy for motion, strength, and balance
For nonoperatively treated fractures, the Cochrane review found neither a removable nor non-removable ankle support superior in terms of function or quality of life in the first six months.
The one non-negotiable: repeat X-rays. A fracture that looks stable at week one occasionally displaces at week two. That's exactly why you come back.
There's good evidence supporting this restraint. The CROSSBAT trial randomized patients with isolated Weber B ankle fractures with minimal talar shift to surgery versus a walking boot. At a minimum 5-year follow-up (mean 7.3 years), surgery showed no clinically or statistically significant advantage in patient-reported ankle function or physical component scores — and the surgical group had a higher rate of adverse events (odds ratio 3.7).
That's a meaningful result. For the right fracture, surgery adds risk without adding benefit. Which is why I spend so much time on the stability question rather than reflexively operating.

Surgical Treatment: Who Does Need Surgery
The indications:
- Unstable or displaced fractures — this is the core indication
- Bimalleolar and bimalleolar-equivalent fractures — inherently unstable, typically treated surgically
- Trimalleolar fractures
- Fracture-dislocations
- Open fractures — urgent
- Syndesmotic instability
- Talar shift on weight-bearing or stress views
- Articular impaction requiring elevation
Current consensus adds an important nuance: active individuals appear to benefit from anatomic reduction and stabilization of all fractures and unstable syndesmotic injuries — sometimes described as "360° treatment," meaning addressing every injured structure rather than just the obvious ones.
Timing — and why this matters more than patients expect.
Skin condition is the principal factor determining when surgery happens.
- Mild swelling → operate early. Most early swelling is fracture hematoma, not tissue edema.
- Abrasions → often benefit from early ORIF, because abrasions become colonized with bacteria within 12–24 hours.
- Significant swelling and fracture blisters → wait. Operating through compromised skin is how you get a wound catastrophe.
- Open fractures → debridement and fixation as soon as possible.
Anatomic reduction remains achievable within about two weeks of injury but becomes progressively harder after that.
There's genuine disagreement in the literature here: some studies find early ORIF equivalent or better and recommend fixation within 24 hours, while others consider delay beyond seven days a poor prognostic factor. I make this call based on the individual soft tissue envelope in front of me, not a rule.
Temporary external fixation — an "ex-fix," a frame with pins above and below — is used when swelling, blistering, or infection prohibits immediate internal fixation. It holds length and alignment while the skin recovers. It's a bridge, not the destination. Patients find it alarming to look at; it does its job.

What Actually Happens in Surgery
Lateral malleolus (fibula).
The standard approach compresses the fracture with a lag screw plus a neutralization plate, or a compression plate alone. A posterior antiglide plate is an alternative with similar clinical outcomes — it reduces soft tissue complications but causes more peroneal tendon irritation. Bridging plates are used for comminuted fractures, common in osteoporotic bone.
Intramedullary fibular nailing is gaining ground, particularly for patients who can't tolerate extensive soft tissue dissection — thin skin, elderly, diabetic, vascular disease — with largely positive results. This has genuinely changed how I approach frail patients.
Medial malleolus.
Usually lag screws or a tension band. For vertical fracture patterns — the supination-adduction type — a buttress plate is used, because screws alone don't resist the shearing force that created the fracture.
Posterior malleolus.
Lag screws or posterior buttress plating. Whether to fix it depends on fragment size, joint surface involvement, and syndesmotic stability. This is where CT earns its keep.
Syndesmosis.
Screws of various configurations, or suture-button (flexible) fixation. Both are in wide use. Accurate reduction matters far more than which device is used — a malreduced syndesmosis is one of the more reliable ways to produce a bad long-term result.
Articular impaction.
If the joint surface is crushed, it gets elevated and supported, often with bone graft. This is not optional. Malreduction of articular impaction — a gap or step greater than 2 mm — is significantly associated with development of early post-traumatic arthrosis.
That 2 mm number is the one I think about most in the operating room.

Recovery: The Real Timeline
This is where the field has genuinely changed, and most of what patients have been told is out of date.
The traditional regimen was six weeks in a cast, non-weight-bearing. That approach has now been called into question by a large number of randomized controlled trials, and current expert consensus states that early weight-bearing and mobilization improve early functional outcomes without increasing complication rates.
The WAX trial — a multicentre randomized non-inferiority trial — tested exactly this. Participants were non-weight-bearing for the first 2 weeks after surgery (standard UK practice), then at the 2-week visit were randomized either to weight-bear as tolerated or to continue non-weight-bearing for another 4 weeks.
The Cochrane review's conclusion: early weight-bearing within three weeks of surgery may improve outcomes in the first six months after injury, though the pooled functional improvement was small and possibly below the threshold of clinical importance. Critically, neither early nor delayed weight-bearing appears to increase the risk of re-operation.
Cochrane also found that a removable ankle support — which lets you take it off to move the ankle gently — may provide better function than a non-removable cast after surgery, with no difference in re-operation risk.
A typical post-operative course for a stable fixation:
Timeframe | What's happening |
Days 0–14 | Splint, strict elevation ("toes above nose"), non-weight-bearing, wound care. Elevation is the whole job in these two weeks. |
Week 2 | Sutures out, wound checked, transition to a boot. Weight-bearing decision made here. |
Weeks 2–6 | Progressive weight-bearing in the boot for most patients. Begin gentle ankle motion out of the boot. |
Week 6 | X-rays. Most fractures showing good healing. Begin weaning from the boot. |
Weeks 6–12 | Transition to shoe with a brace. Formal physical therapy: motion, strength, balance, gait retraining. |
Months 3–4 | Walking normally, back to most daily activity. Swelling still present at day's end. |
Months 4–6 | Impact activity, running progression, return to sport for many. |
Months 6–12 | Continued improvement. Stiffness and swelling gradually resolve. |
Year 1+ | Final result. Some swelling with weather changes and long days can persist beyond this. |
Things I tell every patient:
1. Elevation is not a suggestion. For the first two weeks, your ankle should be above your heart most of the day. Swelling is the enemy of wound healing and the main driver of stiffness later.
2. Ankle swelling lasts a year. Often longer. This is normal and does not mean something is wrong. It's worse at the end of the day, in heat — which in North Texas means most of the year — and after activity.
3. The scar will be numb in spots. Small sensory nerve branches get cut. This usually improves but may not fully.
4. You will be stiff. Getting motion back takes deliberate work. Therapy is where the outcome is determined.
5. Do not skip follow-up X-rays. Fixation can fail silently, especially in poor bone.
Special situations that change the plan:
- Diabetes. Both operatively and nonoperatively managed ankle fractures in patients with diabetes should remain non-weight-bearing for an extended period. This is one place where the early weight-bearing evidence does not apply.
- Osteoporotic bone. Fixation may be less secure; protection is often prolonged.
- Syndesmotic fixation with a screw. Some surgeons protect weight-bearing longer, though practice varies considerably.

Return to Work
Job type | Typical return |
Desk work, able to elevate | 1–2 weeks (often work from home sooner) |
Desk work, commuting/office | 2–4 weeks |
Driving (right ankle) | Typically once out of the boot, off narcotics, and able to brake reflexively — often 6–9 weeks |
Driving (left ankle, automatic) | Often much sooner, once off narcotics |
Light standing/retail | 6–12 weeks |
Nursing, teaching, restaurant work | 3–4 months |
Construction, ladders, uneven ground | 4–6 months |
Firefighter, police, military | 5–6+ months, with functional testing |
Surgical repair of an ankle fracture may require up to 3 months of lost work-hours for one patient, with estimated costs of $8,000–$20,000. Plan for the disruption. Arrange help at home before surgery, not after.

Return to Sport
Let me start with the honest numbers, because they're sobering and patients deserve them upfront.
In a prospective UK population study of sport-related ankle fractures, the overall return rate to sport was 94%, but the mean time to return was 26 weeks and 42% had persisting symptoms.
Broken down by treatment:
- Nonoperative group: 100% returned to sport, mean 20 weeks, 17% with persisting symptoms
- Operative group: 87% returned, mean 35 weeks, 71% with persisting symptoms
Those groups aren't comparable — the surgical patients had far worse injuries. But the message is real: the more severe the fracture, the longer the return and the more likely you are to have some lingering symptoms.
Another study of unstable malleolar fractures found 69.7% returned to physical activity without limitation, 21.75% returned with limitations, and 8.7% did not return. The factors predicting a worse result: bimalleolar or trimalleolar patterns, associated dislocation, and osteochondral injury.
And a large series found that at one year, 88% of recreational athletes had returned to sport but only 11.6% of competitive athletes had — with younger age, male sex, and absence of significant medical comorbidity predicting earlier return.
On the encouraging side, in a series of young athletes treated with ORIF followed by early motion and early weight-bearing, patients returned to their pre-injury level of competition within 2 to 4 months with minimal functional morbidity. Isolated lateral malleolar fractures returned soonest at 6.8 ± 2.4 weeks; isolated medial malleolar fractures took longest at 17.0 ± 9.9 weeks.
The lesson I take from that spread: the fracture pattern, not the calendar, sets the timeline.
My clearance criteria — before anyone returns to cutting or impact:
- Radiographic union
- Full or near-full symmetric range of motion
- 25 pain-free single-leg heel raises
- Single-leg balance for 30 seconds, eyes closed
- Pain-free hopping, then bounding, then cutting
- Completion of a graded running progression without swelling flare
- Confidence — which is not a soft criterion. Athletes who don't trust the ankle get hurt again.
Sport by sport:
Soccer. The single most common sport-related ankle fracture. Cutting, planting, and contact. Nondisplaced fractures treated in a boot: often 3–5 months. Post-ORIF: typically 5–8 months for competitive play. Cleats on firm ground load the ankle hard — I stage the return through grass, then turf, then cleats.
Basketball. Landing and lateral movement. Frequent inversion mechanisms. Post-ORIF: typically 5–8 months. Plyometric progression must be completed before clearance. Bracing for the first season back is reasonable.
Football. Position-dependent. Linemen often return earlier than skill positions; the cutting demands differ enormously. Typically 5–9 months post-ORIF. Turf and cleat interface matters. See A Pro Sports Team Physician's Guide to Foot and Ankle Sports Injuries.
Baseball and softball. Lower rotational demand than field sports. Hitting and throwing return early. Sliding and base running are the limiters — an ankle that gets caught on a slide is exactly the mechanism that broke it. Typically 4–6 months.
Running. Straight-line running is actually forgiving compared to cutting sports. Walk-run progression usually starts around 3–4 months after surgery, on flat, even surfaces. The limiter is usually swelling, not pain. Trails and uneven ground come last.
Pickleball. Enormous in DFW, and the ankle fracture population here is largely middle-aged players who lunged for a dink. Return is often 4–6 months. The lateral shuffle and the sudden forward lunge are the movements I test before clearance. Court shoes with lateral support — not running shoes — matter here.
Golf. Among the earliest returns. Putting and chipping can start early. The trail ankle takes rotational load in the backswing and the lead ankle in the follow-through, so which side you broke matters. Walking 18 holes is usually the limiting factor. Typically 3–4 months, sooner with a cart.
Tennis. Higher intensity than pickleball, with serving load and more court coverage. Typically 5–7 months. Hard courts are less forgiving than clay.
Volleyball. Repetitive jumping and landing, plus the notorious under-the-net foot contact. Typically 5–8 months. Blocking is the last thing cleared.
Dance. Demands extreme range of motion, particularly plantar flexion for pointe and dorsiflexion for plié — and post-fracture stiffness hits both. Dancers need the longest, most individualized rehab. Hardware over a bony prominence can be a genuine problem in a dancer, and I discuss removal more readily in this group. Often 6–12 months to full class.
Gymnastics. Landing forces are extraordinary. Requires full motion, full strength, and full confidence. Realistically 8–12 months for competitive tumbling and vault.
CrossFit. Rowing, upper body, and lifting return early. Box jumps, double-unders, and running are the last things cleared — and box jumps in particular are a common re-injury mechanism. Typically 5–8 months with movement-specific scaling throughout.

Common Mistakes I See
1. Assuming you can walk on it so it isn't broken. Plenty of people walk on fractured ankles. Get the X-ray.
2. Skipping the follow-up visit because the ER said it was "just a small fracture." The weight-bearing X-ray at the one-week visit is where instability gets discovered. This is the single most valuable appointment in the whole process.
3. Not elevating. Patients who sit upright with the leg down for the first two weeks get more swelling, more wound problems, more stiffness, and a slower recovery. This is the highest-yield thing you personally control.
4. Nicotine. Smoking is a significant risk factor for surgical site infection after ankle fracture ORIF. It also impairs bone healing. Vaping, patches, and chew count. If you're having elective surgery on your ankle, stop.
5. Ignoring blood sugar. More on this below, but uncontrolled diabetes is the highest-impact modifiable risk factor in this entire condition.
6. Getting out of the boot too early because it feels fine. Fixation holds the bone while the bone heals. It doesn't replace healed bone. Hardware fails under load.
7. Skipping physical therapy. Surgery restores the anatomy. Therapy restores the function. I've seen technically excellent fixations produce mediocre results because nobody did the rehab.
8. Assuming all the swelling means something is wrong. Twelve months of intermittent swelling is normal.
9. Rushing back to sport on the calendar. Milestones, not dates.
10. Not mentioning that the inside of the ankle hurt too. That's the deltoid. That's the difference between a stable and an unstable injury.

Complications
Honest numbers, from a nationwide registry of 83,666 operatively treated ankle fractures in Finland over 23 years:
- Overall short-term complication rate: 7.2%
- Infection: 4.4%
- Thromboembolic complications (blood clots): 1.6%
- Mechanical complications: 0.4%
- Mortality in the first 4 months: 0.6%
- Complications significantly more common over age 75 (OR 1.53 vs. ages 51–75), and in patients with diabetes, chronic pulmonary, kidney, or liver disease, or peripheral vascular disease
In the American NSQIP database of 4,412 ORIF patients, 5% had any adverse event, with the strongest predictors being insulin-dependent diabetes (OR 2.05), age ≥60 (OR 1.97), ASA class ≥3 (OR 1.69), and bimalleolar fracture (OR 1.6). Notably, insulin-dependent diabetes was associated with increased adverse events while non-insulin-dependent diabetes was not.
The complications in detail:
- Wound healing problems and infection — the most consequential. Meta-analysis identifies diabetes, open fractures, high-energy injuries, smoking, and BMI over 30 as significant risk factors, with antibiotic prophylaxis protective.
- Post-traumatic arthritis — the big one long-term. Covered below.
- Hardware irritation — extremely common, and the most frequent reason for a second operation. The cumulative incidence of fixation device removal was 17% within the first 3 years, higher in younger patients and in bi/trimalleolar fractures.
- Nonunion — uncommon in healthy patients, much more common with diabetes.
- Malunion and loss of reduction
- Blood clots (DVT/PE) — 1.6% short-term. I discuss prophylaxis individually.
- Nerve injury — the superficial peroneal and sural nerves are near standard incisions. Usually a patch of numbness.
- Stiffness — near-universal early, improves with work.
- Complex regional pain syndrome (CRPS) — uncommon but real, and better outcomes come from recognizing it early.
Diabetes deserves its own paragraph. Patients with diabetes are at higher risk after surgical fixation due to impaired neurovascular function and wound healing, and patients with uncontrolled diabetes have higher complication rates than those with controlled diabetes. One study found nonunion odds increased 6.5-fold and Charcot arthropathy odds 7.6-fold in diabetics versus non-diabetics.
But — and this matters — despite the higher complication rates, operative fixation of unstable ankle fractures in diabetic patients reliably leads to a functional lower extremity, with an overall lower rate of complications than nonoperative management. Diabetes is a reason for meticulous technique, extended protection, and frank conversation. It is not a reason to accept an unstable ankle.
If you have diabetes and an unstable ankle fracture, I will explicitly discuss with you and your family the risks of deep infection, loss of reduction, return to the operating room, and — in the worst case — fusion or amputation. That conversation is uncomfortable. It's also the standard of care.

Post-Traumatic Arthritis: The Long Game
This is the reason I care so much about millimeters.
The ankle rarely develops primary osteoarthritis the way hips and knees do. Ankle arthritis generally develops only after trauma — and its impact is severe, with impairment comparable to end-stage kidney disease or congestive heart failure.
The Complete Guide to Ankle Fractures: Symptoms, Treatment, Surgery & Recovery
Post-Traumatic Arthritis: The Long Game (continued)
How often? In patients under 50 followed at least 5 years after malleolar fracture fixation, radiographic arthritis is common — but here is the important nuance patients rarely hear: radiographic arthritis and symptomatic arthritis are not the same thing. Many people have joint space narrowing on X-ray and walk, work, and play without limitation. I treat patients, not films.
What raises the risk:
- Residual talar shift. Even 1–2 mm of lateral displacement dramatically reduces contact area and concentrates load.
- Articular step-off or gap greater than 2 mm. Significantly associated with early post-traumatic arthrosis.
- Malreduced syndesmosis. One of the more reliable predictors of a poor long-term result.
- Initial cartilage damage at the time of injury. Sometimes the cartilage is bruised or fractured in the split second of the injury, and no amount of perfect surgery undoes that. This is why some anatomically fixed ankles still develop arthritis — and it is not a failure of the operation.
- Fracture-dislocation, bimalleolar and trimalleolar patterns, and associated osteochondral lesions of the talus.
If it does develop, it is usually years to decades later, and the treatment ladder starts conservatively — activity modification, bracing, a stiff-soled shoe or rocker sole, anti-inflammatories, and targeted physical therapy. The 2026 AAOS guideline on ankle osteoarthritis is worth reading if you're in that situation, particularly its recommendations against routine PRP and against hyaluronic acid injections used alone: Ankle Arthritis Treatment in Dallas–Fort Worth: What the 2026 AAOS Guidelines Mean for You.
When nonoperative care runs out, the conversation becomes joint-preserving surgery, ankle fusion, or total ankle replacement — decisions the AAOS guideline explicitly frames as shared decision-making rather than one-size-fits-all.
Prognosis in one paragraph: most people who break an ankle do well. Stable fractures treated in a boot generally return to normal function. Unstable fractures fixed anatomically usually do well too, with the caveats that swelling lingers for a year, stiffness takes deliberate work, and severe patterns carry a real rate of persisting symptoms. The strongest predictors of a good outcome are an anatomic reduction, a well-managed soft tissue envelope, controlled blood sugar, no nicotine, and a patient who does the rehab.

Hardware Removal: Should the Plate Come Out?
This comes up in nearly every ankle fracture follow-up, so it deserves a real answer.
The default is that hardware stays. It is not "supposed" to come out. It doesn't set off airport security in any meaningful way, it doesn't attract lightning, it doesn't rust, and it doesn't need to be removed before an MRI.
Reasons I do remove it:
- Symptomatic prominence. The lateral plate sits right under thin skin. In slim patients, dancers, and anyone in boots or skates, it can be genuinely painful against footwear.
- Medial screw heads irritating against the other ankle.
- Syndesmotic screws in some patients, though many are left alone or allowed to loosen or break without consequence.
- Infection or hardware failure.
The realistic numbers: the cumulative incidence of fixation device removal is 17% within the first 3 years, and it's higher in younger patients and in bimalleolar/trimalleolar fractures.
Timing: I wait until the fracture is solidly healed — generally at least 9–12 months. It's a smaller operation than the original, usually outpatient, with a shorter recovery. But it is still an operation with anesthesia, infection risk, and nerve risk, and there is a period of protected activity afterward because the screw holes are temporary stress risers in the bone. Don't remove hardware that isn't bothering you.

Prevention
Some ankle fractures are pure bad luck. Others aren't.
For athletes:
- Treat ankle instability before it breaks something. Repeated sprains that never rehabilitated properly leave you with a joint that gives way — and a giving-way ankle is how fractures happen. See Chronic Ankle Instability Surgery: A Foot and Ankle Surgeon's Complete Guide.
- Balance and proprioceptive training. This is the single best-supported intervention for reducing ankle injury in cutting sports.
- Bracing or taping in high-risk sports, particularly with a history of prior sprain.
- Sport-appropriate footwear. Court shoes for pickleball and tennis, not running shoes. Running shoes have no lateral support and roll.
- Manage training load. Fatigue at the end of a match is when the mechanism happens.
For adults over 50:
- Get bone density assessed if you break an ankle from a low-energy fall. A fracture from standing height is a fragility fracture until proven otherwise, and it's a warning about the hip fracture you haven't had yet.
- Vitamin D and calcium, guided by labs.
- Strength and balance training — genuinely reduces falls.
- Fall-proof the house. Rugs, cords, dark stairs, and the last step off a curb.
- Review medications that cause dizziness or orthostatic drops.
For everyone:
- Control diabetes. It changes both your fracture risk and, dramatically, your complication risk.
- Stop nicotine.
- Don't walk on uneven ground in the dark. Unglamorous, but a large share of my practice.

Frequently Asked Questions
1. Can you walk on a broken ankle?
Often, yes — which is exactly why fractures get missed. Some stable fractures allow near-normal walking with a limp. Being able to bear weight does not rule out a break. If you can't take four steps, that alone warrants an X-ray under the Ottawa rules.
2. How do I know if it's broken or just sprained?
You frequently can't tell from symptoms. Bony tenderness directly over the malleolus, inability to bear weight, and rapid severe swelling all raise suspicion — but an X-ray is the only way to know. A severe sprain can hurt more than a small fracture.
3. How long does an ankle fracture take to heal?
The bone typically unites in about 6–12 weeks. Full recovery — normal walking, no swelling, back to sport — is usually 4–12 months depending on severity. Bone healing and functional recovery are two different timelines, and patients consistently underestimate the second one.
4. Will I definitely need surgery?
No. Roughly 70% of ankle fractures are isolated malleolar fractures, and many of those are stable and treated in a boot. The determining factor is stability, not whether a bone is broken.
5. What is a weight-bearing X-ray and why do I need one?
You stand on the injured ankle while the X-ray is taken. Gravity loads the joint and reveals instability that a lying-down ER film hides. Expert consensus specifically recommends verifying stability with bilateral weight-bearing radiographs before committing to nonoperative treatment. It's the most important test in this whole process.
6. Isn't standing on a broken ankle dangerous?
It's uncomfortable, not dangerous, when done under supervision for a fracture pattern being considered for nonoperative care. It will not "make it worse." It will tell us whether the ankle is stable, which is the information that determines your entire treatment.
7. Why does the inside of my ankle hurt if I broke the outside?
That usually means the deltoid ligament is injured. Functionally that's a two-sided injury — a "bimalleolar-equivalent" — and those are typically unstable and treated surgically. Always mention inner-ankle pain.
8. What is a trimalleolar fracture?
All three malleoli broken — medial, lateral, and posterior. About 7% of ankle fractures. These are unstable and essentially always surgical.
9. What is a Maisonneuve fracture?
A fracture of the fibula up near the knee combined with a syndesmotic injury at the ankle. It's the classically missed pattern, because nobody X-rays the knee when the ankle hurts. If your inner ankle is tender and the ankle films look normal, the whole fibula needs to be examined.
10. What is the syndesmosis?
The fibrous connection binding the tibia and fibula just above the ankle joint — the "high ankle" structure. If it's torn, the two bones separate and the talus loses its socket. Accurate reduction of the syndesmosis matters more for outcome than which device is used to hold it.
11. When should I go to the ER instead of an office?
Obvious deformity, bone through skin, numbness, a pale or cold foot, tented white skin, or severe unrelenting pain. Those need immediate care. Otherwise, an ER X-ray followed by an office visit within a week is reasonable.
12. Do I need surgery urgently, or can it wait?
Open fractures and dislocations are urgent. Most closed fractures are timed to the soft tissues. Mild swelling favors operating early; significant swelling and fracture blisters mean waiting until the skin recovers. Anatomic reduction remains achievable within about two weeks but gets harder after that. There's honest disagreement in the literature about optimal timing, and I make the call based on your skin.
13. Why did they put an external fixator on instead of fixing it?
Because the swelling or skin condition made internal fixation unsafe right then. The frame holds alignment while the soft tissues recover, then the definitive surgery happens. It's a bridge, and it's the right call when the skin can't tolerate an incision.
14. What is the surgery actually like?
An incision over the broken bone, the fragments realigned anatomically, and a plate and screws applied to hold them. Usually outpatient or one night. Often done under regional block plus sedation. Most patients need narcotics only for a few days.
15. How long am I non-weight-bearing?
This has changed. Traditional practice was 6 weeks; the evidence no longer supports that for most patients. Cochrane found that early weight-bearing within three weeks of surgery may improve outcomes in the first six months without increasing re-operation risk. A common approach is non-weight-bearing for the first 2 weeks while the wound heals, then progressive weight-bearing. Diabetics are the major exception and stay non-weight-bearing longer.
16. Cast or boot?
For nonoperative fractures, Cochrane found no clear superiority of either. After surgery, a removable support may provide better function than a non-removable cast, with no difference in re-operation risk. I use a boot in most cases because it allows wound checks and gentle early motion.
17. When can I drive?
Left ankle with an automatic transmission: often within a couple of weeks, once off narcotics. Right ankle: typically once out of the boot, off narcotics, and able to brake reflexively — often around 6–9 weeks. Never drive in a boot on the right foot.
18. When can I shower?
Once the wound is sealed and sutures are out — usually around 2 weeks. Before that, waterproof covers. No submerging, no baths, no pools, no lakes until fully healed.
19. Why is my ankle still swollen after six months?
Because that's normal. Ankle swelling routinely persists for a year, sometimes longer, and is worse at day's end, in heat, and after activity. In North Texas summers this is nearly universal. Compression socks help. It is not a sign of failure.
20. Part of my incision is numb. Will that come back?
Small sensory nerve branches — usually superficial peroneal or sural — are crossed by the incision. A patch of numbness is common. It typically shrinks over 6–18 months but may not fully resolve. It's a cosmetic and sensory issue, not a functional one.
21. Will the hardware need to come out?
Usually not. About 17% of patients have hardware removed within 3 years, most often for symptomatic prominence against footwear. If it doesn't bother you, leave it.
22. Will metal set off airport security or prevent an MRI?
Modern titanium and stainless implants rarely trigger detectors, and no letter is required. MRI is safe with standard orthopedic implants, though there's some image distortion near the metal.
23. Can I get arthritis from this?
It's the main long-term concern. The ankle rarely gets primary arthritis — it gets post-traumatic arthritis. Risk rises with residual talar shift, articular step-off over 2 mm, malreduced syndesmosis, cartilage damage at the moment of injury, and severe fracture patterns. Anatomic reduction is the best protection available.
24. How risky is the surgery?
In a registry of 83,666 operatively treated ankle fractures, the overall short-term complication rate was 7.2% — infection 4.4%, blood clots 1.6%, mechanical complications 0.4%. Risk is significantly higher over age 75 and with diabetes, lung, kidney, liver, or vascular disease.
25. I'm diabetic. Should I still have surgery?
Usually yes, if the ankle is unstable. Diabetics have higher complication rates — nonunion odds roughly 6.5-fold higher and Charcot odds 7.6-fold higher — but operative fixation of unstable ankle fractures in diabetics reliably produces a functional limb with an overall lower complication rate than nonoperative management. Insulin-dependent diabetes carries the higher risk; non-insulin-dependent diabetes was not associated with increased adverse events in the NSQIP data. Control the glucose, extend the protection, and go in with eyes open.
26. Does smoking really matter?
Yes. Smoking is an established risk factor for surgical site infection after ankle fracture fixation and impairs bone healing. This is the single most impactful thing you can change in the weeks around surgery.
27. Do I need a blood thinner?
Thromboembolic complications occur in about 1.6% of operatively treated ankle fractures. Whether you need prophylaxis depends on your personal risk — prior clot, cancer, hormone therapy, obesity, immobility. It's an individual decision, not automatic.
28. Do I really need physical therapy?
Yes. Surgery restores the anatomy; therapy restores the function. Motion, calf strength, single-leg balance, and gait retraining are where the final result is determined. I've seen textbook-perfect fixations produce mediocre outcomes because the rehab never happened.
29. When can I run again?
Typically 3–4 months after surgery for a walk-run progression on flat even ground, later for severe patterns. The limiter is usually swelling rather than pain. Trails and uneven surfaces come last.
30. When can I play pickleball again?
Often 4–6 months. Before clearance I want a pain-free lateral shuffle and forward lunge, since those are the two movements that produce the injury. Wear court shoes with lateral support, not running shoes.
31. Will I get back to my sport?
Most people do. In a prospective study of sport-related ankle fractures the overall return rate was 94% at a mean of 26 weeks — but 42% had persisting symptoms. Nonoperative patients returned at 20 weeks with 17% persisting symptoms; operative patients at 35 weeks with 71%. Those groups had very different injuries, but the pattern is real: worse fracture, longer return, more likely to have something lingering.
32. Will I be as good as before?
For stable fractures, usually yes. For unstable fractures, most patients return to full activity — one series found 69.7% returned without limitation, 21.75% with limitations, and 8.7% didn't return, with bimalleolar/trimalleolar patterns, dislocation, and osteochondral injury predicting worse results. Competitive athletes take substantially longer than recreational ones.
33. My child broke their ankle. Is it different?
Yes, meaningfully. Children have open growth plates, and a fracture through the physis can affect growth. Pediatric patterns like triplane and Tillaux fractures are specific to adolescence and often need CT and precise treatment. A child with ankle pain and growth plate tenderness after an injury needs proper evaluation even with normal-looking films.
34. I'm 70 and broke my ankle from a simple fall. What does that mean?
Two things. First, the fracture needs treating. Second — and often more important — a fracture from standing height is a fragility fracture and a signal about your bone health. It warrants a bone density scan and osteoporosis evaluation, because the next fracture may be a hip.
35. Is it too late to fix it if it healed crooked?
Not necessarily. Malunions can be corrected with osteotomy and realignment, though it's a bigger operation than the original would have been. If the ankle is painful, unstable, or visibly deformed after healing, it's worth an evaluation rather than accepting it.
36. I was told it was "just a sprain" and it's still bad three months later. What now?
Get re-evaluated. Possibilities include a missed fracture, an osteochondral lesion of the talus, a peroneal tendon tear, a syndesmotic injury, a Lisfranc injury, or chronic ankle instability. Three months of ongoing symptoms after an "ankle sprain" is not normal and deserves a second look.
37. Should I get a second opinion?
If you've been told surgery is your only option and no one has explained the stability question or shown you a weight-bearing X-ray — yes. And if you've been told to just live with an ankle that hurts a year later, also yes.

The Bottom Line
- Stability is the whole question. Not whether a bone is broken, but whether the talus stays centered.
- The weight-bearing X-ray is the test that answers it, and it's the one most patients never get.
- Many ankle fractures don't need surgery. The CROSSBAT trial found no advantage to surgery over a boot for minimally displaced Weber B fractures at 5+ years, with more adverse events in the surgical group.
- When surgery is needed, millimeters matter. An articular step-off greater than 2 mm is significantly associated with early arthritis.
- Get moving earlier than you've been told. Early weight-bearing and mobilization improve early function without increasing complications — with diabetics as the major exception.
- Elevation, no nicotine, controlled glucose, and doing the rehab are the four things entirely within your control, and they matter enormously.
- Swelling for a year is normal. Ongoing pain and instability at a year are not.
