The current study compared tunnel diameter as an independent risk factor for fixation failure from the coracoid after transcoracoid coracoclavicular reconstruction. The effect of variation in coracoid size and scapular bone density on fixation failure was also studied. Sixty-two cadaveric scapulae were randomized into 1 of 4 groups: a control group with no coracoid hole, a group with a 4-mm tra...

Background: Lateral end clavicle fractures require operative management because of significant displacing forces trapezius, sternocleidomastoid and weight the arm. Coracoclavicular ligaments are usually torn hampering vertical stability. Currently used implants for osteosynthesis associated with implant impingement on acromion, poor purchase lateral fragment cut-out. There is a lack consensus r...

INTRODUCTION: Many acromioclavicular joint injuries involve damage to the coracoclavicular (CC) ligaments. Some current techniques for CC ligament reconstruction utilize a hole drilled in the coracoid process for placement of a fixation device. Such a hole may increase the probability of coracoid fracture; however, there are no studies in literature that have attempted to evaluate the effects o...

PURPOSE The purpose of this study was to report the clinical and structural outcomes after anatomic coracoclavicular ligament reconstruction (ACCR) with free tendon allografts in patients with grade III and grade V acromioclavicular (AC) joint dislocations. METHODS Thirty-one shoulders underwent primary ACCR with tendon allografts for Rockwood grade III and grade V AC joint dislocations. Preo...

Acromioclavicular (AC) joint instability is a fairly common and particularly limiting injury that may result in persistent pain and reduced quality of life. In most cases, conservative management is successful. However, in the case of a severe AC joint dislocation, surgical intervention may be warranted. Previous surgical techniques for treatment of AC joint instability include screw fixation b...

BACKGROUND Treatment of acute complete acromioclavicular (AC) dislocation is still controversial. Both non-surgical and surgical methods have been reported with similar results. In addition, once surgical treatment is chosen, a satisfactory surgical technique has not been developed yet. METHODS Sixty consecutive patients who sustained 60 acute complete AC dislocations were treated using corac...

INTRODUCTION Acromioclavicular (AC) joint separations are common injuries seen in athletes or laborers in which the AC capsule and coracoclavicular (CC) ligaments are both ruptured [1]. Both surgical and conservative treatments have similar outcomes [2], with both treatments having no guidelines for rehabilitation. The CC ligaments, trapezoid and conoid, have greater structural properties than ...
