  Purpose
A one third of all ankle fractures are bi- or trimalleolar. Traditionally these fractures are treated by both medial and lateral osteosynthesis, sometimes accompanied by osteosynthesis of the posterior malleolus. There is significant evidence that fractures of the lateral malleolus can be treated conservatively if the medial side is stable. However, there isn't a single study comparing standard bi- or trimalleolar fixation with only medial side osteosynthesis and postoperative immobilization with a cast.

Condition Intervention
Trauma Procedure: Talocrural joint is stable after fixation of medial malleolus. Patient is then randomized

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Unimalleolar Versus Bimalleolar Fixation in Bi- or Trimalleolar Ankle Fracture - A Randomized Clinical Trial
