Posterior Buttress Plate for Fractures of Posterior Condyle in Knee Joint (Hoffa Fracture)

Abstract

Posterior condyle fractures of the femur (Hoffa fractures) are generally treated by anterior to posterior-directed screw fixation. However, such screw fixation sometimes failes because of poor bone quality. To enhance the fixation strength, posterior buttress plate was used, and the clinical results including union time, ROM of the knee joint and gait ability were estimated. Although all cases were geriatric fractures, the reduction position was maintained without any displacement. Therefore, the posterior buttress plating method appears to be advantageous in this setting.
