Although acromioclavicular joint separations are fairly common, the occurrence of high-grade acromioclavicular separations that require surgery is low. Various modifications of the Weaver-Dunn procedure have been popular and fairly successful methods to treat severe acromioclavicular separations, despite the fact that reconstructions have been done a number of ways. We report on the results of ...

Although nonoperative treatment is considered the standard of care for the treatment of Grade I and II acromioclavicular (AC) joint injuries, the treatment of Grade III injuries is controversial. There are as many methods of nonoperative treatment as there are for operative stabilization. Most of the literature represents Level IV evidence with very few Level II and III studies upon which to ba...

Fracture of the coracoid process is a rare injury. It can be easily missed when associated with other injuries to the shoulder girdle, for instance, acromioclavicular joint (ACJ) dislocation. Clinical attention is easily drawn to the more obvious ACJ dislocation, hence, the need for further radiological evaluation. We report an unusual case of fracture of the base of coracoid process associated...

The goal of this study was to evaluate the midterm radiologic, clinical, and functional results of the early reconstruction of the severe acromioclavicular joint dislocation using the flipptack fixation button technique. Between December 2006 and December 2009, one hundred thirty-five consecutive patients with acromioclavicular joint separations were admitted to the authors' institution. Fifty ...

The purpose of this study was to assess outcomes following open distal clavicle resection for acromioclavicular joint arthritis or distal clavicle osteolysis, with and without associated acromioplasty. Patients with painful clinical findings limited to the acromioclavicular joint had isolated distal clavicle excision (23 shoulders). Patients with acromioclavicular joint abnormalities and rotato...

Septic pyogenic arthritis of the acromioclavicular joint is a rare entity that occurs in immunosuppressed patients or those with discontinuity of defense barriers. There are only 15 cases described in the literature. The diagnosis is based on clinical features and the isolation of a microorganism in synovial fluid or blood cultures. The evidence of arthritis by imaging (MRI, ultrasound or scint...

A sample of 207 men from the construction industry was studied using an epidemiological technique of cross-sectional design to investigate if sport activities involving the arms increase the risk of developing shoulder tendinitis or osteoarthrosis of the acromioclavicular joint. The relative risk for shoulder tendinitis was estimated to be 9.5 on the right side, and 4.9 on the left side for a l...

Acromioclavicular joint (ACJ) dissociation is one of the common injuries affecting adults. The stability of ACJ largely depends on the integrity of acromioclavicular ligament, coracoclavicular ligament, capsule, trapezius muscle and deltoid muscle. The injury has been classified by Rockwood into six types and treatment options can be guided by the classification. TightRope fixation is one of th...
