PURPOSE To assess the anatomic association of acromioclavicular joint degeneration to supraspinatus outlet impingement and the acromion shape. METHODS Sagittal oblique magnetic resonance images of 49 shoulders in 49 patients were reviewed. 29 of them (mean age, 59 years) underwent surgery for impingement with or without rotator cuff tear (group 1), whereas the 20 controls (mean age, 27 years)...

OBJECTIVE To establish the anatomical relationship of the suprascapular nerve (SSN) located in the suprascapular notch, to the medial border of the base of the coracoid process, the acromial joint surface of the acromioclavicular joint and the anterolateral border of the acromion. METHODS We dissected 16 shoulders of 16 cadavers (9 males and 7 females). The distances from the suprascapular ne...

A 26-year-old Olympic wrestling athlete presented with a pectoralis major muscle injury, glenohumeral instability and acromioclavicular joint dislocation separately. The patient underwent surgical treatment to repair these injuries. The pectoralis major muscle was reconstructed with a semitendinosus tendon graft using the endobutton technique, as described by Pochini et al. Treatment of the tra...

Excessive posterior translation of the residual clavicle after distal clavicle resection can be associated with significant postoperative pain. Although the acromioclavicular capsule has been identified as the primary restraint to translation of the clavicle along this axis, the individual contributions of the anterior, posterior, superior, and inferior components of the capsular ligament have ...

PURPOSE To evaluate the operative findings and postoperative results of one-stage repair on patients with acromioclavicular joint dislocation complicated by rotator cuff tear. METHODS Between 1992 and 1999, one-stage repair was performed on 5 patients with acromioclavicular joint dislocation complicated by rotator cuff tears. Modified Cadenat procedure for acromioclavicular joint dislocation,...

INTRODUCTION Injuries around shoulder and clavicle are quite common. Injuries involving lateral end of clavicle involving acromioclavicular joints are commoner injuries. In this rare injury, we report about a case involving clavicle and scapular spine fracture with acromioclavicular disruption which has never been described in English literature as per our knowledge. CASE REPORT A patient wit...

Objective This study aims to describe the surgical approach to such injuries and to present the clinical and functional outcomes obtained in a cohort of patients. Methods This is an observational retrospective study that included 153 patients with acute acromioclavicular joint dislocation, operated between 1999 and 2015. Clinical evaluation included the following outcomes: Constant functional...
