Cam morphology

Case contributed by Dr Naim Qaqish

Presentation

Long-standing pelvic pain.

Patient Data

Age: 30 years
Gender: Male
X-ray

HIP X-RAY:

Loss of femoral head sphericity with abnormal morphology of the femoral head-neck junction, indicating bilateral CAM deformity with mild degenerative changes.

Bone island is seen in the left femoral neck.

Artefacts are seen projected over the pelvis.

Metallic clips are also seen in the right lower abdomen.

Case Discussion

A 30-year-old gentleman with long-standing pelvic pain and no history of trauma, initially evaluated by hip x-ray. Typical findings of CAM morphology is depicted by osseous bump on the superior femoral neck obliterating the femoro-acetabular sulcus, as a pistol grip appearance of the proximal femur. It is the most common cause of femoro-acetabular impingement in men.

Normally the head-neck junction should be concave superiorly, in cases of CAM morphology, it appears flat or convex and even "bumpy" in appearance.
