Abstract

The functional and radiographic results of closed reduction in 152 congenitally dislocated hips of 119 patients who had been managed between 1938 and 1969 were reviewed retrospectively. The average age of the patients at the time of the reduction was twenty-one months (range, one to ninety-six months). At the time of the latest follow-up evaluation, the average age was thirty-one years (range, sixteen to fifty-six years). The average duration of follow-up was thirty years (range, fifteen to fifty-three years). At the latest follow-up evaluation, the Iowa hip rating averaged 91 points (range, 38 to 100 points) and the Harris hip score averaged 90 points (range, 33 to 100 points). Thirty-five hips were rated Severin Class I; thirty-five, Class II; twenty-eight, Class III; fifty-three, Class IV; and one, Class VI. Disturbance of growth in the proximal end of the femur occurred in ninety-one hips (60 per cent). Eight contralateral hips that had appeared normal also demonstrated disturbance of proximal femoral growth. In many hips, partial physeal arrest could not be determined for ten to twelve years after the reduction. Seventeen hips (twelve patients) had a total replacement when the patients were an average age of thirty-six years (range, nineteen to fifty-three years). Sixty-five hips (43 per cent) had radiographic evidence of degenerative joint disease. Patients who did not have a growth disturbance of the proximal end of the femur or evidence of subluxation tended to function extremely well for many years despite a radiographic result that was less than anatomical. Function tended to deteriorate with time, even in the absence of disturbance of growth in the proximal end of the femur. Despite generally good function at the latest follow-up evaluation, the prognosis for these patients remained guarded.
