Which test for suspected hip labral tears involves supine hip flexion with adduction and abduction while applying downward force, with a positive sign of clicking, grinding, or pain?

• A. Ober's test
• B. Scour test
• C. Faber's test
• D. Trendelenburg's test

Answer: (B)

The Scour test uses a joint-loading maneuver to reveal intra-articular hip pathology, such as a labral tear. In this test the hip is placed in flexion with the knee bent, and downward axial force is applied through the femur while the examiner moves the hip through adduction and abduction. This “scouring” action compresses the femoral head into the acetabulum and sweeps the joint surfaces against each other. If the labrum is torn or there’s degenerative change, this can provoke grinding, clicking, or deep joint pain, giving a positive sign.

Other tests assess different aspects of the hip. Ober’s test checks iliotibial band tightness, Faber’s test (flexion, abduction, external rotation) helps evaluate hip joint or sacroiliac involvement but does not reproduce the intra-articular grinding, and Trendelenburg’s test looks for hip abductor weakness rather than joint pathology.
