Overview
The talus is the central bone of the hindfoot and articulates with the tibia above, the calcaneus below, and the navicular in front. It has a precarious blood supply and no direct muscular attachments. Displaced talus fractures carry a high risk of avascular necrosis and post-traumatic arthritis.
Operative fixation is indicated for essentially all displaced fractures and is typically performed urgently to minimize the risk of skin compromise and to protect the remaining blood supply to the talar body.
Why it's done
Talus fracture fixation is typically considered when imaging and the clinical picture together indicate that the fracture will not reliably heal or function without surgical stabilization. Common indications include:
Displaced talar neck or body fracture
Restoring alignment protects the blood supply.
Subtalar, ankle, or talonavicular joint subluxation or dislocation
Urgent reduction is required.
Open fracture
Immediate debridement and stabilization.
Lateral process fracture with displacement
Often mistaken for an ankle sprain; warrants fixation when displaced.
How it works
Dual anteromedial and anterolateral incisions typically give the needed exposure while preserving skin bridges. The fracture is reduced and fixed with small screws, and a mini-plate is added along the medial or lateral column for comminuted patterns.
For severely displaced patterns, an associated medial malleolar osteotomy is sometimes needed to visualize the joint surface. Fluoroscopy and direct inspection confirm anatomic reduction.
Recovery
Strict non-weight-bearing during early healing is typical. Early ankle and subtalar motion are encouraged once the wound is stable. Serial X-rays monitor for the Hawkins sign — subchondral radiolucency indicating preserved blood supply — at follow-up visits. Avascular necrosis, subtalar stiffness, and post-traumatic arthritis are known long-term complications. Later subtalar or ankle fusion may be considered if arthritis becomes symptomatic.

Weight-Bearing After Repair
Controlled load is part of how bone heals. Once the fracture is stabilized with hardware, gentle weight through the limb stimulates the biology that builds callus and remodels bone — completely offloading a fixed fracture for too long can actually slow healing and stiffen the joint above and below. Full body weight right away, however, can overload the construct before bone has caught up. The right answer sits in between: a partial weight-bearing progression decided by your surgeon based on your fracture pattern, the strength of the fixation, your bone quality, and how the repair looks on post-op imaging. We tell you exactly how much weight the limb can take, when to advance, and what to watch for.
Risks & Why We Still Recommend It
Every operation carries risk. The reason we offer this procedure is that the condition, left untreated, causes avascular necrosis, non-union, and a talar body that progressively collapses and destroys the ankle and subtalar joints. That is the trade we are managing — not eliminating risk, but choosing the smaller of two unfavorable trajectories.
The risks we discuss with patients before talus fracture fixation include:
- bleeding and infection
- anesthesia risk
- avascular necrosis (the talus has a tenuous blood supply and this is the defining risk)
- post-traumatic arthritis of the ankle and subtalar joints
- non-union or mal-union
- hardware irritation
- stiffness
- blood clot (DVT/PE)
The indication to proceed is a displaced talus fracture — these are urgent and the quality of reduction matters enormously. Patients who don't need this operation don't get it.
