Acetabular labrum tear | Pathologies

The acetabular labrum is a band of connective tissue that is located along the rim of the acetabulum, forming a ring around the head of the femur. It acts to increase the surface area of the articular part of the acetabulum, and as a protective layer within the joint complex.

Five causes of labral tears have been identified, including trauma, femoroacetabular impingement, capsular laxity, displasia, and degeneration.

This animation demonstrates a degenerative labral tear, which develops as a result of wear and tear to the hip joint. Labral tears can often be associated with pain and limited mobility of the joint.
