Talus
- Neck
- High risk of avscular necrosis
- Body
- Delay in dx/tx can lead to non-union or subtalar osteoarthritis
Calcaneus
- If suspect fx order an axial view
- Types
- Intra-articular (75%)
- Sclerotic line may be only e/o impacted fracture
- May only be apparent based on decreased Bohler's angle (<30degrees)
- Draw line from highest posterior to highest point of calcaneus
- Draw line from highest anterior to highest point of calcaneus
- Extra-articular (25%)
- Anterior process fx is most common (lateral radiograph)
- Intra-articular (75%)
5th Metatarsal
- Avulsion fracture of the tuberosity
- Due to inversion injury
- Occurs at insertion of peroneus brevis tendon
- Do not confuse unfused apophysis with a fracture!
- Jones' Fracture
- 5th MT fx that occurs within 1.5cm of the tuberosity
- Lies distal to both the tarso-metatarsal joint and joint between 4th and 5th MTs
- Often confused with a fracture of the tuberosity
- Non-union is common; tx with NWB cast
- 5th MT fx that occurs within 1.5cm of the tuberosity
