Brief Summary:
The purpose of this study is to determine whether distal clavicle resection is effective treatments in patients with acromioclavicular joint pain accompanied by rotator cuff tear.

Condition or disease Intervention/treatment
Acromioclavicular Joint Arthritis Procedure: distal clavicle resection

Detailed Description:
Today, acromioclavicular joint syndrome is itself rarely a cause for hospital visit, and the need for its treatment is even rarer. In comparison, patients who suffer rotator cuff tear accompanied by shoulder impingement syndrome often complain of acromioclavicular joint pain. However, often patients who complain of severe pain have no positive findings on X-ray or MRI, or any sign of impingement. On the other hand, there are patients with positive findings on X-ray or MRI who have only little pain. Even a patient who in the out-patient-department complained of acromioclavicular joint pain on pressure may feel pain on pressure in the physical exam performed for rotator cuff tear surgery. The opposite is very frequent as well, so it is often different depending on the time and the performer. In the literature, there are some authors who maintain that a distal clavicular resection must be done when surgery is used to treat the impingement syndrome, while on the other hand, there are those who endorse only complaining (an operation to trim the distal clavicle and the protruding part of adjust the plane acromion in order to level their plane), and also those who propose an all or none approach to either perform a distal clavicular resection or not at all. Thus, there are varying opinions depending on the authors; moreover, these are all observational studies, and none report on the rotator cuff tear injury. The authors of this study hypothesize and will prove that since the osteoarthritic change and pain of the acromioclavicular joint is secondary to impingement syndrome, distal clavicular resection on rotator cuff repair surgery will have no long term effect.
