In the United States acetabular labrum tears usually occur in the anterior or anterior-superior area, possibly due to a sudden change from labrum to acetabular cartilage. [2] The most common labrum tears in Japan are in the posterior region, likely due to the customary practice of sitting on the floor.
The labrum plays an important role in maintaining the biomechanical stability of the hip joint. Studies [6] have shown that damage to the labral tissue can result in disruption of the labral suction-seal, a fluid force paramount in maintaining hip joint integrity. An intact labrum also helps to buttress the hip joint to distraction forces. [7]

The acetabular labrum (glenoidal labrum of the hip joint or cotyloid ligament in older texts) is a fibrocartilaginous ring [1] [2] [3] which surrounds the circumference of the acetabulum of the hip, deepening the acetabulum. The labrum is attached onto the bony rim and transverse acetabular ligament. It is triangular in cross-section (with the ...
