Acromioclavicular joint injury, acromioclavicular separation, AC joint separation, AC separation: An Xray showing a separated shoulder. Notice the separation between the end of the collarbone and the scapula. Specialty: Orthopedics, emergency medicine: Symptoms: Pain, deformity, decreased range of motion [1] [2] Types: Type I, II, III, IV, V ...
The surgery can be performed through an open or arthroscopic procedure. A regimen of physical therapy following surgery is prescribed and most patients experience full recovery within 8 to 10 weeks post-surgery. [1] The procedure was created by, and named for, orthopedic surgeon Eugene Bishop Mumford in 1941. [2] [3]
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 recovery depends upon many factors, including where the tear was located, how severe it was, and how good the surgical repair was. [ citation needed ] It is believed that it takes at least four to six weeks for the labrum to re-attach itself to the scapula bone (shoulder blade), and probably another four to six weeks to get strong.
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 ...
Shoulder pain or tenderness and, occasionally, a bump in the middle of the top of the shoulder (over the AC joint) are signs that a separation may have occurred. Sometimes the severity of a separation can be detected by taking X-rays while the patient holds a light weight that pulls on the muscles, making a separation more pronounced.
Another problem with pain management is that pain is the body's natural way of communicating a problem. [6] Pain is supposed to resolve as the body heals itself with time and pain management. [6] Sometimes pain management covers a problem, and the patient might be less aware that they need treatment for a deeper problem. [6]
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.
