Acetabular labrum
Acetabular Labrum (pronunciation: a-se-ta-bu-lar la-brum) is a ring of cartilage that surrounds the acetabulum of the hip joint. The primary function of the acetabular labrum is to deepen the acetabulum and provide stability to the hip joint.
Etymology
The term "Acetabular" is derived from the Latin word "acetabulum," which means "little vinegar cup." The term "Labrum" is also derived from Latin, meaning "lip" or "edge."
Function
The acetabular labrum contributes to hip stability by deepening the acetabulum, maintaining a vacuum within the joint, and providing proprioceptive feedback. It also acts as a shock absorber, lubricant, and distributes the forces applied to the hip joint.
