II. Mechanism
- Acute Trauma (rare in sports)
- High energy foot injury
- Severe foot dislocations (associated with talar neck Fracture)
- Snowboarder's Fracture
- Lateral process Talus Fracture
- Often misdiagnosed as Lateral Ankle Sprain
- Occurs with acute dorsiflexion and foot inversion under axial load
- Stress Fracture (rare)
III. Imaging
- Initial imaging
- Foot XRay
- Ankle XRay
- CT Imaging Indications
- High index of suspicion for Talus Fracture despite negative XRay
IV. Complications
- Subtalar Dislocation
- Avascular Necrosis
V. Management
- Talar body Fractures
- Talar neck Fractures
- Emergent orthopedic Consultation if displaced talar neck Fracture
- Lateral Process Talar Fracture (Snowboarder's Fracture)
- Talar Stress Fracture
- Relative rest, support shoe, walking boot (CAM Boot), or non-weight bearing
- Resolution may require up to 6 months
- Progressive return to weight bearing
- Use Ankle Brace after return to activity
