Which finding constitutes a positive hip impingement sign?

• A. Pain in the hip joint
• B. Sharp anterior catching pain
• C. Abduction of the hip
• D. Contracture of the hip flexor

Answer: (B)

A positive hip impingement sign shows a sharp anterior catching pain when the hip is moved into positions that compress the front part of the joint, typically flexion with adduction and internal rotation. This mechanical pain reflects contact between the femoral neck and the acetabular rim or labrum, which is the hallmark of impingement. Simple joint pain, abduction-related movements, or a tight hip flexor don’t produce that distinctive anterior catching during the impingement maneuver, so they’re not the expected finding.
