Left hip pain, evaluate for femoral acetabular impingement. The examination is somewhat limited by metallic artifact from metallic pin within the femoral head and neck.ACETABULAR LABRUM: Within the limitations described above, the acetabular labrum is grossly intact.ARTICULAR CARTILAGE AND BONE: A single pin traverses the left femoral head and neck consistent with treatment for slipped femoral capital diaphysis. There is abnormal prominence of the anterior femoral head neck junction with an alpha angle measuring approximately 68 degrees compatible with a cam deformity. The visualized bone marrow signal intensity is within normal limits.SOFT TISSUES: The visualized soft tissues and musculature are grossly within normal limits. ADDITIONAL
1.Exam somewhat limited by metallic artifact from SCFE fixation. 2.Cam deformity of the left hip. No gross labral tear is evident.
