Description[edit | edit source]
The McCarthy Test is a clinical test used to aid in the diagnosis of a hip labral tear. Painful popping, clicking, or catching while performing the test indicates a possible hip labrum tear.[1]
Clinically Relevant Anatomy[edit | edit source]
The acetabulofemoral (hip) joint is the largest and most stable joint in the human body. The joint is surrounded by ligaments that work to keep this articulation intact. Movements of this joint are facilitated by the proximal head of the femur articulating in the acetabulum of the pelvic girdle. The acetabular labrum is a soft-tissue structure which lines the acetabular rim of the hip joint.[3]In normal hip joint biomechanics, the labrum is crucial in retaining a layer of pressurized intra-articular fluid for joint lubrication and load support/distribution.[3] Its seal around the femoral head is further regarded as a contributing to hip stability through its suction effect.[3]

Technique[edit | edit source]
Step 1: The patient should be laying supine with their head supported and with both arms rested to their side in a comfortable position.
Step 2: The examiner should then passively flex the affected hip to end range.
Step 3: The clinician should then externally rotate the hip as the leg is moved back into extension.
Step 4: Repeat steps 1 and 2 but internally rotate the hip as the leg is moved back into extension.

Evidence[edit | edit source]
The McCarthy Test has never been subject as the single form of diagnostic studies, which is why the clinical value remains questionable.[4]
