At upper right is the start of Perthes disease with avascular necrosis (bone tissue death, black area) of the femoral head. At lower left is a femoral head deformity, with a flattened femoral head. At lower right is slipped capital femoral epiphysis (SCFE), where the femoral head slips off its shaft. The joint tissues include cartilage (pink), the synovial membrane (blue), and the joint capsule (red). For the individual images, see C029/0657-60.
