Indications
- Displaced talar neck fractures, Hawkins II to IV
- Urgent reduction of dislocated fragments to protect skin
- Undisplaced fractures confirmed on CT can be treated in a cast
- Open fractures need urgent debridement and stabilisation
Position
- Supine, bump under the hip
- Image intensifier positioned for lateral, AP and Canale views
- Thigh tourniquet
Operative Steps
- Dual anteromedial and anterolateral approaches show comminution and prevent varus malreduction
- Protect the deltoid branch of the posterior tibial artery
- Reduce the neck, checking length on both sides
- Two screws, posterior to anterior screws are biomechanically stronger
- Lateral mini fragment plate across comminution to hold length
- Check with Canale view
- Medial malleolar osteotomy for body extension or a dislocated body
- Avoid stripping the dorsal neck and the sinus tarsi to preserve blood supply
- Temporary external fixation if soft tissues are poor
Postoperative Care
- Non weight bearing for 8 to 12 weeks
- Hawkins sign at 6 to 8 weeks, subchondral lucency, means the dome is revascularising
- Early ankle and subtalar motion once the wound has healed
- Radiographs at 2, 6 and 12 weeks
Complications
- Avascular necrosis
- Varus malunion
- Subtalar and ankle arthritis
- Wound breakdown and infection
- Nonunion is less common than AVN
