Background
- Results from external rotation force applied to foot
- Leg equivalent of Galeazzi fracture
- Components:
- 1. Fibula fracture (anywhere from head or as far down as 6cm above ankle joint)
- 2. Deltoid ligament rupture or medial malleolus fracture
- 3. Injury then directed upward and laterally tearing interosseous membrane and anterior inferior tibiofibular ligament
Diagnosis
- Long leg film that includes ankle
- Increase in medial clear space of ankle joint
- Tibiofibular clear space widened >5mm
- High fibular fracture
- Signs of syndesmotic injury
Differential Diagnosis
Distal Leg Fracture Types
- Tibial plateau fracture
- Tibial shaft fracture
- Pilon fracture
- Maisonneuve fracture
- Tibia fracture (peds)
- Ankle fracture
- Foot and toe fractures
Treatment
- Usually requires surgical intervention
- Long leg posterior splint until further f/u
