Axial and Rotational Malreduction (Golf Club Deformity) in Distal Femur Fractures

Objectives: To describe malreduction of supracondylar distal femur fractures stabilized with lateral femoral locking plates and determine whether a mismatch in axial lateral distal femur anatomy and lateral distal femoral plate design contributes to supracondylar distal femoral fracture malreduction. Materials and Methods: OTA/AO 33A were simulated in 7 cadaver femurs and fixed with a lateral distal locking femoral plate placed flush to the lateral femoral condyle (group 1). In group 2, the anterior flange of the plate was externally rotated 10 degrees in relation to the lateral condyle. A motion capture system measured translation and rotation of the articular segment as shaft screws were applied, reducing plate to femoral diaphysis. Articular segment movement was compared between groups using paired Student t test, P
