Summary

Nine patients with chondrolysis secondary to slipped capital femoral epiphysis of the hip were followed up from a minimum of 7 to a maximum of 19 years (average, 13.7 years) after the onest of the disease. The degree of slipping of the proximal epiphysis of the femur was severe in five patients and moderately severe in four patients. The nine patients were treated with non-weight bearing, anti-inflammatory drugs, and physical therapy. The disease had a good resolution, with gradual regression of pain, and radiographs showed restoration of the joint space in an average of 10 months. At follow-up, mild coxalgia after prolonged activity was present in five patients, whereas in the one patient with concomitant avascular necrosis, pain was much more intense. All patients had some limitation of range of motion of the hip. It was most restricted in two patients, one with associated avascular necrosis and one with a severe slip. In all patients, radiographs showed restoration of the joint space. In the group with severe degrees of slipping, there were marginal osteophytes of the femoral head and the acetabulum. Significant arthrosis was present in the patient treated conservaticely and in the patient with associated ischemic necrosis. In this long-term study of chondrolysis secondary to slipped capital femoral epiphysis, the overall prognosis was benign and was determined by the degree of slipping of the proximal epiphysis of the femur and concomitant aseptic necrosis. However, the authors believe that the patients with radiographic signs of degenerative joint disease may have a poor long-term prognosis.
