Transtrochanteric anterior rotational osteotomy for slipped capital femoral epiphysis: a report of five cases.

We have performed a transtrochanteric anterior rotational osteotomy on five patients with severe chronic slipped capital femoral epiphysis. Four patients were free from clinical symptoms, whereas one patient continued to feel a dull pain in the hip. Radiographic evaluation indicated that the osteotomy was able to correct even a severe slip without any deformity around the trochanteric region. There were complications in two cases: a posteromedial tilt at the osteotomy site and a focal avascular necrosis in the anterolateral epiphysis.
