Glossary of Shoulder Pain
Acromioclavicular joint The acromioclavicular joint is an articulation between the acromion (part of the shoulder blade) and clavicle. Between this there are a number of ligaments such as the coracoclavicular, coracoacromial ligament and conoid ligament.
Acromioclavicular (AC) dislocation The clavicle (collarbone) is forced out of position. Usually resulting from a fall on an outstretched hand.
Calcific tendinitis This is where the tendon of the rotator cuff becomes calcified due to a prolonged period of abrasion.
Frozen shoulder - also known as adhesive capsulitis. Frozen shoulder is where the joint capsule of the shoulder usually hardens in response to trauma or surgery. The result is a generalized stiffening of the shoulder.Capsule Another term you may hear related to the anatomy of the shoulder joint is the capsule. A capsule is a membrane or sac in the body, that surrounds a joint such as the shoulder. The joint capsule of the shoulder goes around the entire shoulder.
The shoulder is a very complex assembly with a wide range of movement produced by many different bones, muscles and tendons acting together. Unfortunately this flexibility also makes it more unstable and therefore susceptible to injury. Some of these are detailed below.
Tear of the labrum Here the edge of the shoulder joint is torn during trauma. Most common in contact sports such as rugby.
Magnetic resonance imaging or MRI MRI stands for Magnetic Resonance Imaging and is a common procedure for medical diagnosis today. MRI is especially useful to show the soft tissues of the body and can therefore be of great help in the diagnosis of your shoulder pain or rotator cuff injury. MRI uses a magnetic field to reveal neurological problems, musculoskeletal, cardiovascular and oncological issues.
The rotator cuff The rotator cuff is another important part of your shoulder and one often heard associated with shoulder pain. It consists of a number of tendons and related muscles . The rotator cuff helps stabilize the shoulder, but can also be easily damaged due to a tear or an impingement of the shoulder to give a rotator cuff injury.
Tear of the rotator cuff This is where one of the muscles of the rotator cuff tears. You can have a full thickness tear or a partial thickness tear. Arthritis of the shoulder Arthritis of the shoulder is caused by wear and tear changes in the acromion of the shoulder, giving rise to shoulder impingement syndrome.
Shoulder Bursa A bursa is a fluid-filled sac located between bones and tendons or muscles around joints such as the shoulder. These enable smooth movement but can become inflamed. If this happens your doctor will tell you that you have bursitis.
Dislocated shoulder Shoulder dislocation occurs when the arm bone (humerus) is forced out of the shoulder joint, usually through trauma.
Shoulder Impingement This occurs when the tendons of the rotator cuff are pinched in the subacromial space. (This is the space below the acromion part of the scapula).
Shoulder Muscles Another important part of the anatomy of the shoulder is the shoulder muscles. These muscles connect to the three bones of the shoulder and are responsible for different functions. Some of these muscles include the serratus subclavius, pectoralis minor, sternocleidomastoid, levator scapulae, trapezius and deltoid.
Shoulder X-Ray If you land heavily on your shoulder then you may have fractured one of the bones that make up the shoulder joint. X-rays can help to determine this. X-rays do not show soft tissue like muscles and tendons but they can be used to eliminate the possibility of a fracture. Other forms of radiography such as X-ray contrast dyes or ultrasound may also help to show up more information.
Supraspinatus tendinitis This is tendinitis of the supraspinatus muscle, one of the muscles of the rotator cuff . Most often caused by abrasion under the Acromioclavicular joint.
Whiplash and Whiplash Associated Disorder Whiplash Associated Disorder (WAD). Whiplash is a medical condition that occurs when due to a sudden force, the head moves forward and then backward, very quickly. Due to the sudden slamming of the head, neck and shoulder injuries are common in patients with whiplash. Whiplash injuries occur frequently in car accidents.
