PURPOSE To review the functional and radiological results of patients after coracoclavicular ligament reconstruction. METHODS Five patients aged 21 to 50 (mean, 37) years with acute Rockwood type-III acromioclavicular dislocation underwent coracoclavicular ligament reconstruction with autogenous gracilis tendon grafts. Patients were either active in sports or heavy manual workers. Assessments...

BACKGROUND Our purpose was to investigate the clinical efficacy of arthroscope-assisted acromioclavicular ligament reconstruction in combination with double endobutton coracoclavicular ligament reconstruction for the treatment of complete acromioclavicular joint dislocation. METHODS During the period from February 2010 to October 2012, ten patients with Rockwood types IV and V acromioclavicul...

Background & Aims: Acute acromioclavicular (AC) joint dislocation is common in shoulder injuries. Considering the biomechanics of this joint, the use of a treatment method, which can restore joint physiology and biomechanics to the extent possible, is important. This study aimed to compare the treatment of acute AC joint dislocation by screw fixation with and without ligament reconstruction. Me...

Operative intervention is recommended for complete acromioclavicular (AC) joint dislocation to restore AC stability, but the best operative technique is still controversial. Twelve fresh-frozen male cadaveric shoulders (average age, 62.8 7.8 years) were equally divided into endobutton versus the modified Weaver-Dunn groups. Each potted scapula and clavicle was fixed in a custom made jig to allo...

Methods to reconstruct the coracoclavicular ligaments anatomically have been described. No clear advantage of 1 technique has been elucidated. The authors' hypothesis was that the biomechanical properties of a modified knot fixation technique would be similar to the anatomical double-bundle technique. Sixteen matched cadaveric shoulders were used for this study, and 1 additional shoulder was us...

BACKGROUND Numerous surgical techniques have been described to address injuries to the coracoclavicular ligaments. PURPOSE To compare the biomechanical properties of tendon graft reconstructions with those of the native coracoclavicular ligaments and various other repair methods. STUDY DESIGN Controlled laboratory study. METHODS Eleven fresh-frozen human cadaveric shoulders were tensile t...

The Ligament Augmentation and Reconstruction System® (LARS®) represents a popular synthetic anatomical reduction method for acromioclavicular joint dislocation by means of coracoclavicular ligament reconstruction. To our knowledge, no early failure has been documented in the literature. We present two unusual cases of LARS failure, one at four months after implant and the other at three weeks, ...

Injury of the acromioclavicular (AC) joint can occur as the result of direct or indirect trauma. The treatment of these injuries has remained controversial. The first reported surgical procedure for internal fixation of AC dislocation was performed by Cooper in 1861 using silver wire to secure the AC joint. Since then, a wide variety of techniques have been used. In 1972, Weaver and Dunn descri...

Acromioclavicular (AC) joint injuries are common and often seen in contact athletes, resulting from a fall on the shouldertip with adducted arm. This joint is stabilized by both static and dynamic structures including the coracoclavicular (CC)ligament. Most reconstruction techniques focus on CC ligament augmentation as the primary stabilizer of the AC joint.The best surgical technique for some ...
