Shoulder dislocations are a common injury, with anterior shoulder dislocation among male patients being the most common presentation. A patient with recurrent shoulder instability, anterior-superior escape, and chronic subscapularis tendon rupture following multiple shoulder stabilization surgeries presents the surgeon with a complex and challenging case. This report describes a 40-year-old man...

BACKGROUND There has been much controversy over specific tests for diagnosis of supraspinatus tendon tear. The aim of this study was to evaluate the metabolic activity of the deltoid and rotator cuff muscles while maintaining the full-can and empty-can testing positions using 2-deoxy-2-[18 F]fluoro-D-glucose (18 F-FDG) positron emission tomography (PET)/computed tomography (CT). METHODS Ten h...

The histopathological changes associated with rotator cuff tears include thinning and disorganization of collagen fibers, the presence of granulation tissue, increased levels of glycosaminoglycans, fibrocartilaginous metaplasia, calcification, fatty infiltration, and necrosis of the tendon margin with cell apoptosis. The biochemical changes include an increase in the expression of matrix metall...

BACKGROUND This study used a chronic rotator cuff (RC) tear model to investigate the effect of microfracture as a bone marrow-stimulating (BMS) technique for RC healing. METHODS A chronic retracted RC tendon tear model was created bilaterally in the subscapularis tendons of 20 New Zealand rabbits. The tendons were repaired after 8 weeks using a single-row configuration. Tendons in the right s...

INTRODUCTION: Subscapularis (SSC) tendon tear is detected in about 20-40% of the patients with rotator cuff tear during surgery. Magnetic resonance imaging (MRI) scans have been used as a diagnostic tool for predicting the presence of SSC tear. But it is difficult to diagnose the SSC tear correctly. The purpose of this study is to evaluate the significance of various preoperative MRI findings t...

Methods: Two pediatric, skeletally immature patients were identified with complete subscapularis tendon tears resulting from athletic participation. Extent of rotator cuff pathology was evaluated through physical examination, X-rays, magnetic resonance imaging (MRI), and diagnostic arthroscopy. Two different suture anchor systems were utilized for repair of the tendon tear in Case 1 and Case 2:...
