[Lamellar coxitis. Apropos of 30 cases].

The authors have studied 30 cases of acute necrosis of articular cartilage complicating slipped capital femoral epiphysis. They recall the main features of this condition: stiffness and narrowing of the joint space. They analyse the importance of the degree of slipping and of the type of treatment in the aetiology of this complication. Weight bearing should be suppressed as early as possible, for a long period of time. However early signs of degenerative arthrosis were found in most of the hips.
