Overview

X Ray

X-Rays of the hip joint are absolutely necessary. Diagnosis is made predominantly by X-ray study, together with physical examination (MRIs have also been found useful for judging the extent of the deformity). Sufferers typically have limited range of motion in their hip, particularly when rotating the joint.

Early signs

  • Small femoral epiphysis (96%)
  • Sclerosis of the femoral head with sequestration and collapse (82%)

Late signs

  • Radiolucent crescent line representing a subchondral fracture
  • Femoral head fragmentation and femoral neck cysts from intramedullary hemorrhage or extension of physeal cartilage into metaphysis, loose bodies, and coxa plana.
  • Coxa magna or remodeling of the femoral head, which becomes wider and flatter and similar in appearance to a mushroom.
