II. Epidemiology
- Represents 15% of all Calcaneal Fractures
III. Description
IV. Types
- Avulsion Fracture
- Associated with recurrent Lateral Ankle Sprain
- Mechanism
- Ankle inversion and
- Plantar flexion
- Compression Fracture
- High energy injury (e.g. Motor Vehicle Accident)
- Often associated with other Fractures
- Mechanism: Forced dorsiflexion
- Intra-articular Fracture
- High energy injury (e.g. Motor Vehicle Accident)
V. Symptoms
- Provocative: Walking (but not necessarily standing)
VI. Signs
- Point tenderness at calcaneocuboid joint
- Anterior to lateral malleolus by 3 cm
VII. Differential Diagnosis
VIII. Radiology: Foot XRay
- Best seen on lateral Calcaneus view
- Accessory ossicle at anterior process is normal variant
- Consider foot CT or MRI
IX. Management
- Nondisplaced Fracture
- Short Leg Cast and non-weight bearing for 4-6 weeks
- Large, displaced Fracture or non-union
- Surgery
