Femoroacetabular impingement: Cam type

Case contributed by Dr Alborz Jahangiri


Bilateral chronic hip pain.

Patient Data

Age: 54
Gender: Female

There is cam deformity of both femoral necks that predisposes to impingement on hip flexion.There is severe joint space narrowing and established marginal osteophytes of the acetabular roof, more prominent on the left side.

Case Discussion

Two types of joint deformities have been described as causes of early degenerative joint disease. Pincer type (over-coverage of the femoral head) and cam type (bump formation at the femoral neck and asphericity) deformity which can also co-occur.

They can lead to femoro-acetabular impingement and acetabular damage and predispose to early osteoarthritis.
