3. The severity of symptoms with avascular necrosis is usually related to the degree of articular surface disruption.
4. Symptoms similar to hip OA: groin pain with weight-bearing, pain on internal rotation, flexion, adduction.
5. Radiographs: sclerosis of femoral head or collapse. MRI/CT is the inx of choice.
