Background
- Almost always associated with other injuries, often misdiagnosed as ankle sprains
- Talar neck fracture most common (~50%)
- Dorsiflexion with axial loading, snowboarders
- Talar body fracture (~20%)
- Hindfoot in either supination or pronation, high energy trauma
- Lateral process fracture (~10%)
- Dorsiflexion with axial loading
- Posterior process, medial or lateral tubercle very commonly misdiagnosed as ankle sprains
- Talar head fracture least common
Clinical Features
Differential Diagnosis
Foot and Toe Fracture Types
Hindfoot
Midfoot
Forefoot
Diagnosis
- CT often required for accurate diagnosis
- AP, lateral, possibly Canale view
Management & Disposition
- Major fracture (talar neck and head)
- Immediate ortho consultation required (high rate of avascular necrosis)
- Minor fracture
- Posterior Ankle Splint
- Non-weight bearing, short leg cast if minimally displaced fracture
- Ortho referral
