1. We reviewed the cases of all patients with slipped capital femoral epiphysis at the University Hospital of West Indies. Forty-seven hips in thirty-six black patients were evaluated, and in 40 per cent of these hips chondrolysis developed.
2. The appearance of roentgenographic changes of chondrolysis was predictable. There was a very high percentage occurring within one year of diagnosis of slipped epiphysis and within six months of closure of the proxinial femoral growth plate.
3. The persistent absence of motion in all planes following slipping of the capital femoral epiphysis was a constant finding in patients with chondrolysis. This loss of motion can be diagnostic of impending chondrolysis and is usually present before the appearance of the roentgenographic changes.
4. The microscopic changes suggest that the primary lesion is not necrosis of cartilage but a replacement of articular cartilage by pannus formation.
