labrums

Labrums is a term that can refer to two distinct anatomical structures, both found in the human body. The glenoid labrum is a ring of fibrocartilage that surrounds the rim of the glenoid cavity, which is part of the shoulder joint. This structure deepens the socket and increases the stability of the glenohumeral joint, providing a crucial surface for the head of the humerus to articulate with. Tears of the glenoid labrum are common sports injuries and can cause pain, instability, and clicking in the shoulder.

The acetabular labrum is similarly a ring of fibrocartilage located around the rim of the acetabulum, the socket of the hip joint. It enhances the stability and congruity of the hip joint by deepening the socket and creating a seal that helps maintain intra-articular pressure. Like the glenoid labrum, the acetabular labrum can also be torn, leading to hip pain, clicking, and reduced range of motion. These tears are often associated with conditions like femoroacetabular impingement. Both types of labrums play a vital role in the proper function and stability of their respective joints.
