Definition/Description
[edit | edit source]
An acetabular labral tear can cause pain if the labrum is torn, frayed, or damaged. Labral tears cause groin pain or pain in the anterior side of the hip, and less commonly buttock pain . This mechanically induced pathology is thought to result from excessive forces at the hip joint for example: A tear could decrease the acetabular contact area and increase stress, which would result in articular damage, and destabilize the hip joint .[1]
Anterior labral tears: the pain is more consistent and is situated on the anterior hip (anterosuperior quadrant) or at the groin. They frequently occur in European countries and the United States.
Posterior labral tears: are situated in the lateral region or deep in the posterior buttocks. They are less frequently in European Countries and United states but are frequent in Japan.
Clinically Relevant Anatomy[edit | edit source]
The acetabular labrum is a fibrocartilaginous rim, which encompasses the circumference of the acetabulum. It helps to keep the head of the femur inside the acetabulum, and varies greatly in form and thickness.
The labrum has 3 surfaces: aninternal articular surface next to the joint (avascular), external articular surface(vascular) contacting the joint capsule, and a basal surface that is attached to the acetabular bone and ligaments. The transverse ligaments surround the hip and help hold it in place while moving.
On the anterior side the labrum is triangular in the radial section and posterior side it is dimensionally square but with a rounded distal surface.
The functions of the acetabularlabrum are: joint stability, sensitive shock absorber, joint lubricator, and pressure distributor; decreasing contact stress between the acetabular and the femoral cartilage
