Labrum Anatomy

It coats the surface of the socket area with a soft cartilage enabling the shoulder to move more freely and painlessly. Circumferentially orientated layer with radial reinforcing filaments.

Labral Tears Of The Shoulder Anatomy And Causes Video

A labral tear occurs when the cartilage is torn.

Labrum anatomy. The anterior portion is most vulnerable when the labrum tears. Keeping joint fluid inside the hip joint capsule joint fluid. Glenoid labrum gross anatomy.

Anatomy of the shoulder featuring the humerus upper arm bone and the labrum. It acts and looks almost like a washer sealing the two sides of the joint together. The term labrum is used in anatomy to designate a lip edge or brim.

The labrum serves several purposes including. In medicine a ring of fibrocartilage fibrous cartilage around the edge of the articular joint surface of a bone. The glenoid labrum glenoid ligament is a fibrocartilaginous structure not a fibrocartilage as previously thought rim attached around the margin of the glenoid cavity in the shoulder blade.

Allowing for a significant range of motion. Deepening the joint and increasing the surface area of the hip socket by 21 1. The outer glenoid is vascular and the inner glenoid is avascular 4.

In anatomy and physiology the term labrum is used to refer to an edge or a brim. The shoulder joint is considered a ball and socket joint. Blood supply and innervation.

It contributes to shoulder stability and when torn can lead to partial or complete shoulder dislocation. The term labrum is used in anatomy to designate a lip edge or brim. The acetabular labrum is a ring of cartilage that surrounds the acetabulum of the hip.

The labrum is thickest posterosuperiorly and widest anterosuperiorly. The glenoid labrum is similar to the meniscus of the knee. It provides an articulating surface for the acetabulum allowing the head of the femur to articulate with the pelvis.

The labrum surrounding the shoulder socket is called the the glenoid labrum. One arm of the biceps tendon long head also attaches to the shoulder labrum at its top. Helping maintain alignment between the hips ball and socket.

The labrum is the attachment site for the ligaments and supports the ball and socket joint along with the rotator cuff tendons and muscles. It helps provide stability to the shoulder by deepening the socket and serving as a firm attachment point for the ligaments that connect the humerus to the glenoid. It is a fibro cartilaginous rubbery structure which encircles the glenoid cavity deepening the socket providing static stability to the glenohumeral joint.

It is triangular in cross section. The fibrocartilage is is arranged in three distinct layers. The glenoid labrum is approximately 4 mm thick and is round or triangular in cross section.

The labrum is a thick fibrous ring that surrounds the glenoid.
