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