What does capsular hypertrophy mean?

Capsular hypertrophy may reflect the increased amount of stress associated with joint incongruity and instability. To perform MRI solely to detect disorders of the acromioclavicular joint would not be efficient. However, standard MRI sequences of the shoulder regularly include the acromioclavicular joint.

What is acromioclavicular hypertrophic change?

Acromioclavicular osteoarthritis is a type of shoulder arthritis that involves degenerative changes to the cartilage and other structures in the acromioclavicular joint—leading to pain, stiffness, and weakness in the front of the shoulder.

How do you treat acromioclavicular disease?

Treatment is typically an arm sling, bed rest, ice and heat therapy, and anti-inflammatory drugs. Most people recover full motion of the shoulder and arm within 6 to 8 weeks, often with the assistance of physiotherapy. Type III – Both acromioclavicular and coracoclavicular ligaments are torn.

What is capsule of acromioclavicular joint?

The acromioclavicular joint is completely enclosed by a fibrous capsule. Its inner surface is lined with a synovial membrane, bounding the synovial cavity of the joint. The capsule is externally supported by the acromioclavicular ligament and trapezius muscle on its superior aspect.

What does mild acromioclavicular degenerative changes mean?

Osteoarthritis of the acromioclavicular (AC) joint is a common condition causing anterior or superior shoulder pain, especially with overhead and cross-body activities. This most commonly occurs in middle-aged individuals because of degeneration to the fibrocartilaginous disk that cushions the articulations.

What does acromioclavicular mean?

The acromioclavicular, or AC, joint is a joint in the shoulder where two bones meet. One of these bones is the collarbone, or clavicle. The second bone is actually part of the shoulder blade (scapula), which is the big bone behind the shoulder that also forms part of the shoulder joint.

What is mild degenerative changes acromioclavicular joint?

What movement does acromioclavicular joint allow?

The AC joint is a plane type synovial joint, which under normal physiological conditions allows only gliding movement. As it attaches the scapula to the thorax, it allows an additional range of motion to the scapula and assists in arm movement such as shoulder abduction and flexion.

What is acromioclavicular degeneration?

ACJ degeneration is a progressive problem where there is localised pain in the ACJ area. Tenderness is localised to the tip of the shoulder and a swelling may develop. It is usually painful to lie on the shoulder or perform activities which compress the ACJ.
