What is a gllenoid cavity?

Glenoid cavity, also known as gluenoid fossa shoulder blades, is depression in the bone of the shoulder blade or shoulder blade in which the upper part of the upper arm or humerus is set. The shoulder has three joints. One of these joints, called the glenohumeral joint, is the ball in the joint and the glueid cavity is part of the drawer of this joint. Its function is to allow the humerus head to rotate widely around the shoulder point. Bones, tendons and muscles in combination with the joint also allow the upper body to pull, push and lift objects, and without this drawer, the arm would have limited mobility.

While the joints of the balls and sleeves, such as the hip joint, can carry and maintain the joint of the shoulder victim part of its stability for a greater range of motion. Increased flexibility of the shoulder joint is caused by finer tendons and ligaments in this area. In addition, the head of the humerus is much larger than the glenoid cavity, which makes it prone to jumping.

How GlenidnThe cavity, so the humerus is covered with cartilage to allow practically without friction in the joint. The cartilage also helps to make a shallow cavity of the glueid cavity somewhat stronger. In the glenohumeral joint, the cartilage is surrounding the head of the humerus at the point where it hits the center of the cavity. On the other hand, the Glenoid cavity has a cartilage collar surrounding it called a labrum. Labrum watches around the thickened part of the cartilage on the humerus head, which makes this cursory drawer medium stronger.

The most common injury involving this cavity are fracture, Labrum damage or joint dislocation. Glenoid fracture is a glenoid socket turning, resulting in pain and swelling that prevents the injured person to pick up or extend it throughout the body. This type of fracture is treated with mobilization during healing or surgically bone screws.

Labrum damage or tear causes a reduced range of movement in the shoulder, intense pain and even clicking on sound during shoulder rotation. To repair the cartilage to reduceThe swelling uses rest and anti -inflammatory drugs, followed by physical therapy. If damage is serious, arthroscopic surgery may be necessary to repair tears.

pain and often uselessness after dislocation is often obvious. The dislocated arm must be moved by a healthcare worker and the arm should be maintained as deepened as possible until the doctor can be achieved. As soon as the joint appears back, the shoulder is immobilized while tendons and muscles are treated.
