Quick Answer:
Quick Answer: Ankle fractures range from isolated stable fibular avulsion fractures that heal in a boot to complex trimalleolar fracture-dislocations requiring urgent surgical reduction and fixation. Proper classification — Weber A/B/C for fibular fractures, and Lauge-Hansen for injury mechanism — guides treatment decisions. Stable ankle fractures (Weber A, stable Weber B) are managed with removable boot or cast immobilization for 4–6 weeks with progressive weight-bearing. Unstable fractures (displaced Weber B, Weber C, bimalleolar/trimalleolar patterns, syndesmotic injury, medial-sided ligament involvement) typically require open reduction internal fixation (ORIF) with plates and screws for anatomic restoration of the ankle mortise. Dr. Biernacki performs the full spectrum of ankle fracture treatment — from initial evaluation and casting in the office to outpatient surgical fixation for complex patterns.
Ankle fractures are among the most common skeletal injuries, accounting for approximately 10% of all fractures. At Balance Foot & Ankle, Dr. Biernacki provides comprehensive ankle fracture care — from acute evaluation and splinting through weight-bearing casting, surgical fixation when indicated, and complete post-operative rehabilitation. The critical initial decision — operative vs. non-operative management — depends on fracture pattern, stability, alignment, and patient factors including bone quality, activity level, and medical comorbidities.
Ankle Fracture Classification
Dr. Biernacki uses both the Weber (Danis-Weber) classification for fibular fractures and the Lauge-Hansen classification for injury mechanism to guide treatment. Weber A (below the level of the ankle joint, below the syndesmosis): typically stable, managed non-operatively. Weber B (at the level of the joint, involving the syndesmosis): stability depends on medial-sided integrity — stress views or MRI assess syndesmotic stability; unstable patterns require fixation. Weber C (above the syndesmosis, with obligate syndesmotic injury): typically unstable, requires ORIF with syndesmotic fixation. Special patterns: bimalleolar (fibula + medial malleolus) — unstable, requires ORIF; trimalleolar (fibula + medial malleolus + posterior malleolus) — high instability, typically requires ORIF including posterior malleolus fixation if fragment >25% of articular surface; Maisonneuve fracture (proximal fibula fracture with deltoid ligament injury) — proximal fibula fracture with ankle instability, requires syndesmotic fixation.
Non-Operative Management
Stable ankle fractures — isolated Weber A injuries and stable isolated fibular fractures without medial-sided involvement — are managed non-operatively. Initial management: posterior short-leg splint with elevation and ice for 48–72 hours until swelling subsides, followed by transition to a removable pneumatic walking boot. Weight-bearing as tolerated is permitted for most stable fractures. Serial radiographs at 1 week and 3 weeks confirm maintained alignment. Transition to supportive footwear with physical therapy begins at 6 weeks with confirmed healing on X-ray. Return to full unrestricted activity: typically 3–4 months from injury for stable fractures.
Surgical Fixation (ORIF)
Unstable ankle fractures are treated with open reduction internal fixation (ORIF) to restore the anatomic ankle mortise and allow early functional rehabilitation. The fibula is fixed with an intramedullary nail or lateral plate and screws; the medial malleolus with partially threaded cancellous screws or tension band construct; the posterior malleolus with posterior-to-anterior lag screws for large fragments. Syndesmotic disruption is addressed with suture-button devices or temporary syndesmotic screws. Dr. Biernacki performs ankle ORIF at accredited surgical facilities; patients are splinted post-operatively with transition to non-weight-bearing cast/boot for 6 weeks, then progressive weight-bearing with physical therapy. Most patients return to full activity 4–6 months post-operatively.
Special Considerations: Diabetic Ankle Fractures
Ankle fractures in diabetic patients — particularly those with peripheral neuropathy — carry significantly higher complication rates: delayed union, non-union, hardware failure, infection, and Charcot neuroarthropathy development. Non-operative management in neuropathic patients requires extended immobilization (12+ weeks) and strict non-weight-bearing. Surgical fixation uses augmented constructs with additional fixation points and extended weight-bearing restrictions. Dr. Biernacki applies specialized diabetic fracture protocols to this high-risk population, with frequent follow-up and aggressive monitoring for complications.

Dr. Tom Biernacki’s Recommendation
Ankle fractures are one of those injuries where the initial evaluation really matters. Missing a syndesmotic injury on a Weber B fracture because you didn’t do stress views — and then treating it non-operatively — results in a chronic unstable ankle mortise and early arthritis. My practice is to classify every ankle fracture completely, get appropriate stress imaging when stability is uncertain, and make a definitive operative vs. non-operative decision at the first visit. Patients deserve a clear plan from day one, not weeks of ‘wait and see.’

Frequently Asked Questions
How do I know if my ankle is broken or just sprained?
A high-impact injury with significant immediate swelling, inability to bear weight, and point tenderness directly over the bone (not just the ligaments) warrants X-ray evaluation. The Ottawa Ankle Rules are a validated clinical tool — tenderness over the medial or lateral malleolus, or inability to bear weight, has high sensitivity for fracture. When in doubt, get X-rays.
Can a broken ankle heal without surgery?
Yes — many stable isolated fibular fractures heal excellently with boot or cast immobilization. Operative treatment is reserved for unstable patterns where non-operative management carries high risk of malunion, chronic instability, or arthritis. The fracture classification determines which treatment is appropriate.
How long does a broken ankle take to heal?
Stable fractures managed non-operatively: 4–6 weeks to fracture union, 3–4 months to full activity. Surgical ORIF cases: 6 weeks non-weight-bearing, then 4–6 months total to full unrestricted activity. Diabetic patients and elderly patients with osteoporosis typically require extended healing times.
When can I go back to sports after an ankle fracture?
Return-to-sport criteria include: radiographic evidence of fracture union, full or near-full range of motion, symmetric strength compared to the uninjured side, and functional testing (single-leg balance, jumping, cutting). For most ankle fractures, return to sport occurs 3–5 months after injury with appropriate rehabilitation.

Frequently Asked Questions
How long does treatment take to work?
Most patients see improvement in 4-8 weeks with consistent conservative care. Persistent symptoms after 8 weeks need imaging and escalation.
When is surgery needed?
Surgery is reserved for cases that fail 3-6 months of conservative care, structural deformities, or fractures requiring stabilization.
Is this covered by insurance?
Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Custom orthotics often require diabetic or post-surgical justification.
