There is currently no "gold standard" surgery to repair acromioclavicular separations, and many surgeries have been created. However, this is one of the more common fixes. The original surgery is described as follows. Resection of the distal 2 cm of distal clavicle; Detaching the acromial end of the coracoacromial ligament, and possibly ...
The coracoacromial ligament may impinge and compress rotator cuff muscle or tendon. [3] It may be damaged during a shoulder injury. [4]The attachment of the coracoacromial ligament may be moved from acromion to the end of the clavicle when reconstructing the acromioclavicular joint.
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.
Those suffering from osteoarthritis in the acromioclavicular joint can opt for this procedure when non-surgical alternatives (e.g., cortisone injection) are unsuccessful. [1] The surgery can be performed through an open or arthroscopic procedure.
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]
[1] [3] Pain can be managed during the procedures either by procedural sedation and analgesia or injected lidocaine into the shoulder joint. [20] Injecting lidocaine into the joint may be less expensive and faster. [4] If a shoulder cannot be relocated in the emergency room, relocation in the operating room may be required. [1]
When performing the Neer impingement test, the elbow should be extended, humerus in internal rotation and the forearm pronated. When the examiner is passively flexing the arm forward, it is causing compression of the structures between the greater tuberosity, inferior acromion process and the acromioclavicular joint. [1]
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.
