The acromioclavicular joint is commonly affected by trauma to the shoulder girdle due to its subcutaneous position. Athletes who participate in contact sports, such as hockey, football, rugby, and soccer, are particularly susceptible to such injuries. These injuries, however, also occur during noncontact sports such as baseball, skiing, and cycling. The majority of acromioclavicular injuries oc...

A type VI acromioclavicular joint injury with a supracoracoid location of the distal end of the clavicle (VIa) may be associated with low energy injuries and, in association with a clavicle fracture, can successfully be treated with reduction of the dislocation, fixation of the clavicle, and may not require reconstruction of the acromioclavicular ligaments. An infracoracoid location (VIb) is hi...

We describe the technical aspects of an arthroscopy-assisted procedure indicated for the management of acute unstable acromioclavicular joint injuries, consisting of a synthetic augmentation of both the coracoclavicular and acromioclavicular ligaments, that anatomically reproduces the coracoclavicular biomechanics and offers fixation that keeps the torn ends of the ligaments facing one another,...

BACKGROUND Joint injections and aspirations are used to reduce joint pain and decrease inflammation. The efficacy of these injections is diminished when they are placed inadvertently in the wrong location or compartment. The purpose of this study was to determine whether the use of varying sites or imaging techniques affects the rate of accurate needle placement in aspiration and injection in t...

BACKGROUND Surgical treatments for acromioclavicular (AC) joint dislocation present with some complications. The present study was designed to evaluate the double-button fixation system in the management of acute acromioclavicular joint dislocation. METHODS This cross sectional study, done between February 2011 to June 2014, consisted of 28 patients who underwent surgical management by the do...

A 53-year old man presented with chronic left shoulder pain, unresponsive to anti-inflammatory treatment. There was no history of injury or chronic overuse. Radiography showed degenerative changes of the acromioclavicular joint, an acromion type 1, and the presence of coracoclavicular joint. CT scan confirmed the presence of a joint between the clavicle and the coracoid process with degenerativ...

The treatment of the sports related dislocation of the acromioclavicular joint remains controversial. This study was carried out to determine whether or not a combined surgical procedure consisting of repair and polydioxanone (PDS)-cord augmentation of the coracoclavicular ligaments, fixation of the acromioclavicular joint with a single Kirschner wire as well as the repair of the acromioclavicu...

BACKGROUND Although it has been established that surgical treatment for acromioclavicular joint disruption (types IV-VI and type III in overhead throwing athletes and heavy laborers) is preferred, the literature is inconclusive about the best type of surgery. PURPOSE With the goal of avoiding the potential complications of hardware use, the authors present a coracoclavicular functional stabil...
