OPS-Code 5-805.2:

You have had an operation on your shoulder joint.

The shoulder joint is the joint between the shoulder blade and the humerus.There is a flat recess to the side of the shoulder blade. This is the glenoid cavity. In the glenoid cavity is the spherical upper end of the humerus. This is the head of the humerus.The edge of the glenoid cavity is encircled by a thin layer of cartilage which slightly enlarges the surface of the joint. This stabilizes the shoulder joint.The shoulder has a muscle group made up of 4 muscles. The muscles begin to the front and rear of the shoulder blade. Tendons attach them to the humerus at the top. These muscles stabilize the shoulder joint and are involved in various arm movements.

The shoulder joint is surrounded by a joint capsule that protects and stabilizes it. The thin layer of cartilage around the glenoid cavity (shoulder socket) is connected to the joint capsule and tendons in this area. If muscles, tendons, the cartilage layer or the joint capsule are damaged, the shoulder joint can become unstable. The humeral head may then no longer be held firmly in the glenoid cavity.

The layer of cartilage around your glenoid cavity was reattached to the front of your shoulder blade. Typically, the front part of the joint capsule is also tightened during this procedure. Tendons and ligaments can also be reattached in the correct position.The body’s ligaments consist of tough connective tissue. Ligaments hold the joints together and ensure that we can move our joints normally.
