Subscapularis tendon tears present a technical challenge because both diagnosis and arthroscopic treatment can be difficult. One difficulty is the limited visualization and working space of the anterior shoulder. Although most tears of the subscapularis are partial- or full-thickness tears of the upper third of the tendon, occasionally, larger or more retracted tears are encountered. Various te...

OBJECTIVES To seek evidence of the danger molecule, high-mobility group protein B1 (HMGB1) expression in human tendinopathy and thereafter, to explore mechanisms where HMGB1 may regulate inflammatory mediators and matrix regulation in human tendinopathy. METHODS Torn supraspinatus tendon (established pathology) and matched intact subscapularis tendon (representing 'early pathology') biopsies ...

BACKGROUND Subcoracoid impingement has been implicated as a cause of anterior shoulder pain and subscapularis tendon tears. PURPOSE/HYPOTHESIS The purpose of this study was to evaluate the bony anatomy of the coracoid process and the subcoracoid space. We hypothesized that age-related changes that may contribute to subcoracoid impingement occur in the subcoracoid space. STUDY DESIGN Descrip...

Clinical appearance of isolated traumatic rupture of the subscapularis tendon confirmed with sonography, double contrast CT and intraoperatively in two patients has been presented. The mechanism of the injury--forceful external rotation and hyperextension of the arm, increased passive external rotation and positive "lifft of test" may lead to the correct diagnosis.

The rotator interval of the shoulder joint is located between the distal edges of the supraspinatus and subscapularis tendons and contains the insertions of the coracohumeral and superior glenohumeral ligaments. These structures form a complex pulley system that stabilizes the long head of the biceps tendon as it enters the bicipital groove of the humeral head. The rotator interval is the site ...

BACKGROUND The bicipital tunnel is the extra-articular, fibro-osseous structure that encloses the long head of the biceps tendon. METHODS Twelve cadaveric shoulder specimens underwent in situ casting of the bicipital tunnel with methyl methacrylate cement to demonstrate structural competence (n = 6) and en bloc harvest with gross and histologic evaluation (n = 6). The percentage of empty tunn...

Accepted for publication 1 1 February 1994 Abstract Objectives-To analyse the collagen composition of normal adult human supraspinatus tendon and to compare with: (1) a flexor tendon (the common biceps tendon) which is rarely involved in any degenerative pathology; (2) degenerate tendons from patients with chronic rotator cuff tendinitis. Methods-Total collagen content, collagen solubility and ...

BACKGROUND Pathology of the long head of the biceps tendon (LHB) is commonly associated with rotator cuff tears (RCTs). Superior labral anterior-posterior (SLAP) lesions can also occur with RCTs. The purpose of this study was to include SLAP lesions as part of LHB pathology in surgical cases of RCT and define the role of SLAP lesions in RCTs. METHODS We retrospectively evaluated clinical data...

OBJECTIVES The aim of this study was to evaluate the results from arthroscopic tenodesis of the long head of the biceps brachii (LHBB) on the tendon of the subscapularis muscle, with regard to the presence of pain, subscapularis lesion, presence of Popeye's sign and patient satisfaction. METHODS A prospective cohort study was conducted on 32 patients with LHBB lesions, through preoperative in...
