Treatment of coxa brevis.

Coxa brevis of the hip results in a morphologic change of the proximal femur creating pain and fatigue, leg-length discrepancy, and altered gait. The most common cause is a growth alteration of the proximal femoral physis secondary to ischemic necrosis of the proximal femoral epiphysis. This article describes the Morscher osteotomy-a unique femoral neck-lengthening technique. The outcomes of this successful and predictable technique are resolution of symptoms of fatigue and hip discomfort; the absence of nonunion, infection, or hardware failure; and restoration of normal proximal femoral morphology and biomechanics.
