CUNEIFORM OSTEOTOMY OF THE FEMORAL-NECK IN THE TREATMENT OF SLIPPED CAPITAL FEMORAL EPIPHYSIS - A FOLLOW-UP NOTE

The long-term clinical and roentgenographic results of cuneiform osteotomy of the femoral neck at the level of the physis in sixty-one patients (sixty-six hips) who had a slipped capital femoral epiphysis of more than 30 degrees were reviewed. The result was excellent in fifty-five hips, good in six hips, fair in two hips, and poor in three hips. The results in thirty-eight of these hips were reported in 1984. Osteoarthrosis developed in six patients; it was mild in four patients, moderate in one, and severe in one. Two patients had evidence of chondrolysis. The pin was found to have penetrated into the joint in all six of the patients who had osteoarthrosis and in one patient who had chondrolysis. Complete avascular necrosis of the femoral head developed in two patients and segmental avascular necrosis in one; all three patients had an acute-on-chronic slip.
