Shoulder joint anatomy

The shoulder: a complex joint

The shoulder is a very complex joint. Strictly speaking, it consists of several joints that act together. This way, they ensure the large range of movement of the arm. Other parts of the shoulder are three bones (bone of the upper arm, shoulder blade and collarbone), three muscle groups as well as numerous tendons and ligaments for the joint capsule.

In frozen shoulder, for example, the capsule and the synovial membrane of the shoulder joint are affected. In concrete terms, it involves a hardening and shrinkage of the connective tissue structures that form the joint capsule.

In comparison to the other joints, the shoulder can be dislocated relatively easily. The joint's socket is small in relation to the head of the humerus. Although this makes the joint enormously mobile, it also makes it unstable.

Dislocated shoulder

A dislocated shoulder may only be reduced by a doctor – and as quickly as possible The shoulder is then usually immobilised for eight to ten days using elastic supports, splints, slings or a plaster cast. The shoulder immobilisation orthosis medi Arm fix and the shoulder support Omomed from medi are particularly easy for the patient to put on without help from others.
