Background
- Usually high-energy trauma
- 80% medial dislocations
- 25% open, with lateral more likely
- Associated with fractures ~50%
Clinical Features
Medial
- Foot displaced to supination
Lateral
- Foot displaced to pronation
Differential Diagnosis
Foot diagnoses
Acute
- Foot and toe fractures
- Subtalar dislocation
- Metatarsophalangeal joint sprain (turf toe)
- Acute arterial ischemia
- Calcaneal bursitis
Subacute/Chronic
- Diabetic foot infection
- Peripheral artery disease
- Plantar fasciitis
- Trench foot
- Ingrown toenail
- Paronychia

Evaluation
- Xrays
Medial
- Talar head superior to navicular on lateral XR
Lateral
- Talar head inferior to navicular on lateral XR
Management
- Closed reduction and short leg NWB cast first-line, with ortho consult
