X-Rays of the hip joint are absolutely necessary. X-rays will show a small, flattened and fragmented head of femur. A bone scan may be useful in helping determine the extent of the avascular changes. A hip aspiration may be performed if there is suspicion of a septic arthritis. The diagnostic finding will show patchy areas of avascular necrosis and eventually fragmentation and flattenning in the femoral head.
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.
