The shoulder joints are the most movable joints in the body. These joints help to position your hand and major tasks like stretching the arm to get hold of an object, pulling a door, lifting heavy loads and such. The shoulder joints mainly consist of two joints that help to perform major functions, shoulder joint and glenohumeral joint. There is also another important part of shoulder joint called the acromioclavicular joint that links the extreme top of the shoulder joint to the back of the rib cage or the thorax.
The shoulder joint is made up of three types of bones, clavicle or the collar bone, scapula or the shoulder blade and the humerus or the upper arm bone. You may check out the following details of the three major joints of the shoulder.
Glenohumeral Joint – The glenohumeral joint is the main part of the shoulder joint. It is actually a ball and socket joint that allows the hand to rotation in a circular motion and also to stretch out and up from the body. The ball is the rounded head of the humerus and the part of the lateral scapula. The dish shaped part of the lateral scapula that forms the socket is called the glenoid fossa. The capsule consists of soft tissues that envelope the entire joint and is attached to the scapula, humerus and the head of the biceps. The capsule is covered by a thin and smooth membrane called the synovial membrane.
Acromioclavicular Joint – The acrominocular joint is in between the highest point of the scapula and the end of the clavicle. The joint is toughened by a ligament called coracoclavicular ligament which is present at the point of articulation of the joint.
Sternoclavicular joint – This joint is present at the end of the medial clavicle along the highest point of the sternum. The joint is formed by the articulation of two bones, the triangular shaped and rounded clavicle and the convex shaped manubrium. The joint is supported by the intra-articular disc and a compact capsule.
The movement of the shoulder joints takes place with the aid of the thick band of tissues, muscles, tendons and ligaments. Shoulder joints can develop disorders that can be caused due to the wear and tear of the muscles or tissues attached to the joints. Dislocation of the ball of the humerus from the socket of the scapula may also cause shoulder joints disorder. Even with the progress of age the bones of the joints become weak and tend to be brittle in nature. There are several medicines available in the market that would help you to restore and recover from the shoulder joint pains.
