Femoroacetabular impingement - cam lesion

Case contributed by Alborz Jahangiri
Diagnosis certain

Presentation

Bilateral chronic hip pain.

Patient Data

Age: 55 years
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 morphology (overcoverage of the femoral head) and cam morphology (bump formation at the femoral neck and asphericity) can also cooccur.

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