Surgery may be done arthroscopically or as open surgery. The impinging structures may be removed in surgery, and the subacromial space may be widened by resection of the distal clavicle and excision of osteophytes on the under-surface of the acromioclavicular joint. [4] Damaged rotator cuff muscles can be surgically repaired.
Exercise increases blood flow to the muscles affected which enhances blood flow. Regular exercise is a crucial part of the healing stages of adhesive capsulitis. Specific exercises are highlighted to enhance recovery. Another useful tool can be anti-inflammatory medications. These provide temporary relief which aid in exercise exertion.
Subacromial bursitis is a condition caused by inflammation of the bursa that separates the superior surface of the supraspinatus tendon (one of the four tendons of the rotator cuff) from the overlying coraco-acromial ligament, acromion, and coracoid (the acromial arch) and from the deep surface of the deltoid muscle.

A separated shoulder, also known as acromioclavicular joint injury, is a common injury to the acromioclavicular joint. [2] The AC joint is located at the outer end of the clavicle where it attaches to the acromion of the scapula. [2] Symptoms include non-radiating pain which may make it difficult to move the shoulder.
Grade I is slight displacement of the joint, and a badly stretched or partially torn AC ligament. It has the normal separation of <4 mm. Grade II is a partial dislocation of the AC joint with a complete disruption tear of the AC joint and a partial disruption of coracoclavicular ligament. The AC gap is >5 mm. Grades I and II never require ...
The acromioclavicular joint and sternoclavicular joint also play a role in shoulder movements. [3] White hyaline cartilage on the ends of the bones (called articular cartilage) allows the bones to glide and move on each other, and the joint space is surrounded by a synovial membrane. Around the joint space are muscles - the rotator cuff, which ...

The coracoclavicular ligament is a strong stabilizer of the acromioclavicular joint. [2] It is also important in the transmission of weight of the upper limb to the axial skeleton. There is very little movement at the AC joint. [citation needed]
