Its acromion process articulates with clavicle at lateral end of clavicle to form acromioclavicular Following diagram would explain the relation of the scapula to the thorax. . I would advice you to see a physician so that your problem can be. The coracoid process is a bone which serves as the connection point for the ligaments that connect the shoulder blade to the collarbone. Most collarbone fractures do not require surgery (particularly, if the fractured area My doctor says that I don't need surgery and that I will be fine in a couple of months. The collarbone attaches the sternum to the scapula (shoulder blade). . In most states, you can seek physical therapy advice without a.
Shoulder pain is common in our community. In younger people, shoulder pain is more likely to be due to an accident or injury. However, as you get older, natural wear and tear occurs in the shoulder joint and the rotator cuff tendon.
Over time, this may become persistent pain. The good news is that with appropriate treatment shoulder pain will improve so you can get back to doing the things you enjoy. The shoulder The shoulder is a complex, highly mobile structure made up of several components. There are two joints in the shoulder: Strong connective tissue forms the shoulder capsule. This keeps the head of the humerus in place in the joint socket. The joint capsule is lined with a synovial membrane.
It produces synovial fluid which lubricates and nourishes the joint. Strong tendons, ligaments and muscles also support your shoulder and make it stable. What causes shoulder pain? There are many causes of shoulder pain and not all of these are due to problems of the shoulder joints or associated structures. Osteoarthritis Cartilage is a smooth, cushiony tissue that covers the ends of bones where they meet in a joint.
Healthy cartilage helps your joints move smoothly.

Over time cartilage can become worn, or it may become damaged due to injury or an accident, leading to the development of osteoarthritis. Inflammation of the shoulder capsule The synovial membrane of the shoulder may become inflamed — this is called 'synovitis'.
Synovitis may occur as a result of another condition for example, rheumatoid arthritis or it may happen as a result of an injury, or the cause may be unknown. Frozen shoulder 'adhesive capsulitis' is a condition that occurs when the shoulder capsule thickens and becomes inflamed and tight. There may also be less synovial fluid to lubricate the joint. As a result, the shoulder becomes difficult to move.
Frozen shoulder may occur as a result of another condition if the shoulder has been immobilised for example, due to surgery or injury. Sometimes the cause of shoulder pain may not be known. Inflamed bursa Pain associated with an inflamed bursa is also common in the shoulder.
A bursa is a small fluid-filled sac that reduces friction between two structures, such as bone, muscle and tendons. In the shoulder, the bursa that sits between the rotator cuff tendon and the bony tip of the shoulder acromion can become inflamed, most commonly with repetitive movements.
Injuries and sprains Ligaments are soft tissues that connect bones to bones. If ligaments are injured or sprained, it can cause short term pain. This may be the result of the humerus coming partially out of the joint socket subluxation or if the humerus comes completely out dislocation. Triceps The long head of the triceps arises from the infraglenoid tubercle. Teres Minor Teres minor arises from the upper two-thirds of the rough strip on the dorsal surface along the lateral border.
Teres Major It arises from the lower one-third of the rough strip on the lateral aspect of the lateral border. Levator Scapulae is inserted along the dorsal aspect of the medial border, from the superior angle up to the root of the spine. Rhomboideus Minor It is inserted into the medial border dorsal aspect opposite the root of the spine of the scapula.
Rhomboideus Major Rhomboideus major is inserted into the medial border dorsal aspect between the root of the spine and the inferior angle. Omohyoid The inferior belly of the omohyoid arises from the upper border near the suprascapular notch. Ligaments of Scapula Capsule The margin of the glenoid cavity gives attachment to the capsule of the shoulder joint and to the glenoid labrum.
The margin of the facet on the medial aspect of the acromion gives attachment to the capsule of the acromioclavicular joint. Coracoacromial Ligament The coracoacromial ligament extends between the coracoid process and the acromion.
This ligament protects the head of the humerus from dislocating during motion. Coracohumeral ligament It is attached to the root of the coracoid process. Coracoclavicular ligament It is attached to the coracoid process.

The trapezoid part attaches to the superior aspect and the conoid part near the root. The suprascapular nerve passes through the foramen and the suprascapular artery is above the ligament. Suprscapular nerve course, Image Credit: The suprascapular vessels and nerve pass deep to it.
In shoulder abductionthe scapulohumeral movement is in the ratio of 2:
