Presentation
Chronic bilateral hip pain, for more than seven years.
Patient Data
Severe joint space narrowing, significant osteophytosis with subchondral sclerosis, and cysts formation in the bilateral hip joints, mainly in the anterosuperior aspect of the joints. Cam morphology of the bilateral femoral head-neck junction.
Case Discussion
Cam morphology is one of the causes of femoroacetabular impingement and is associated with early-onset osteoarthritis as in this middle-aged man who presented with chronic hip pain. The morphology is most prominent in the anterosuperior position of the femoral head-neck junction, which was demonstrated in this case.
