The glenoid is a shallow, curved socket that is part of the shoulder blade (scapula). It is located on the lateral side of the scapula and articulates with the head of the upper arm bone (humerus) to form the shoulder joint. The glenoid is covered with a layer of smooth cartilage, which allows for smooth and painless movement of the shoulder joint.
The glenoid is an important structure in the shoulder joint, as it provides stability and support for the arm. It is also involved in a number of shoulder movements, including abduction (lifting the arm away from the body), flexion (bringing the arm forward), and rotation.
Disorders or injuries that affect the glenoid or the surrounding structures of the shoulder joint can cause pain, stiffness, and difficulty with movement. Treatment for these conditions may include physical therapy, medications, or surgery. If you are experiencing shoulder pain or discomfort, it is important to speak with a healthcare professional for proper diagnosis and treatment.« Back to Glossary Index
