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.
