Glenoid labrum
Glenoid Labrum
The Glenoid Labrum (pronounced: /ˈɡliː.nɔɪd ˈlæ.brʊm/) is a fibrocartilaginous structure in the shoulder joint. The term "glenoid" is derived from the Greek word "glenoeides", meaning socket-like, and "labrum" is Latin for lip or edge.
Anatomy
The Glenoid Labrum is a ring of fibrocartilage that surrounds the Glenoid cavity, deepening it and providing stability to the Shoulder joint. It is continuous with the Articular cartilage of the glenoid cavity and blends with the shoulder joint capsule and the tendon of the long head of the biceps brachii.
Function
The primary function of the Glenoid Labrum is to deepen the glenoid cavity, increasing the surface area and thus the stability of the Shoulder joint. It also serves as an attachment site for the shoulder joint capsule and the Glenohumeral ligaments.
Clinical Significance
Injury to the Glenoid Labrum, often through trauma or repetitive shoulder motion, can lead to a condition known as a Labral tear. Symptoms of a labral tear can include pain, decreased range of motion, and instability in the shoulder. Treatment options can range from physical therapy to surgery, depending on the severity of the tear.
