Gerdy's tubercle osteotomy for the treatment of coronal fractures of the lateral femoral condyle.

Coronal fractures of the femoral condyle (Hoffa fractures) are intraarticular fractures that are commonly treated surgically by open reduction and internal fixation. Surgical fixation is demanding because anatomic reduction is mandatory and adequate exposure is often difficult. Herein we describe a new technique that permits excellent visualization and fixation of lateral Hoffa fractures based on osteotomy of Gerdy's tubercle and reflection of the attached iliotibial band.
