Outcome Measures

Primary Outcomes (1)

union of lateral malleolar fracture
Serial radiographs will be obtained at 2, 6, and 12 weeks postoperatively to assess union and screw position. Union will be confirmed by the presence of bridging trabeculae across the fracture site and resolution of fracture lines.
12 weeks postoperative

Secondary Outcomes (2)

absence of pain
12 weeks postoperative
foot function and range of motion
12 weeks postoperative

EXPERIMENTAL

Procedure: Double Compression Screw Fixation for Symptomatic Non-union of Lateral Malleolar Ankle Fractures

Interventions

Double Compression Screw Fixation for Symptomatic Non-union of Lateral Malleolar Ankle FracturesProcedure

A lateral approach to the distal fibula will be made, centered over the non-union site. Dissection will be carried down through the subcutaneous tissue with care to protect the superficial peroneal nerve. Minimal soft tissue striping will be performed to preserve vascularity. The fibular non-union site will be exposed, and fibrous tissue interposed at the fracture line will be carefully debrided using curettes and rongeurs, the sclerotic edges of the non-union will be freshened until punctate bleeding bone (the "Paprika sign") will be observed. The fracture will be anatomically reduced under direct visualization and temporarily held with reduction clamps, under fluoroscopic guidance, insert appropriate guide wire then 6.5 mm Double compression screws will be inserted across the fracture site in perpendicular orientation, from distal to proximal, traversing the non-union zone. Screw trajectory will be chosen to maximize bone purchase while avoiding joint penetration or screw collision.
