Tears of the subscapularis tendon have been significantly recognized as a source of shoulder pain and dysfunction in the past decade, thanks to arthroscopic evaluation of the shoulder and biomechanical and anatomical studies of the tendon. Current classification of subscapularis tendon tear is based on insertion site of the tendon. Recently, a classification for non-insertional types of subsc...

abstract   background: despite being the largest rotator cuff tendon of the shoulder, the function and clinical relevance of subscapularis pathology has been largely ignored in the literature. although many studies have focused on subscapularis tears recently, majority of them reported techniques for open repair. the advent of arthroscopy and arthroscopic repair techniques has opened new fronti...

Isolated ruptures of the subscapularis and anterosuperior rotator cuff lesions are encountered more rarely than supraspinatus or anteroposterior rotator cuff tears. In certain circumstances, reconstruction of the tendon may not be possible due to fatty degeneration and atrophy of the subscapularis muscle or poor tendon quality. Tendon transfer may represent the only surgical option for treatmen...

With the advent of arthroscopy and arthroscopic repair techniques, the diagnosis and treatment of subscapularis tears have been significantly advanced. The precise etiologic factors related to subscapularis tears remain unclear. We propose that subcoracoid stenosis and subcoracoid impingement cause a "roller-wringer effect" on the subscapularis tendon. This effect increases the tensile loads on...

OBJECTIVE The objective of our study was to retrospectively evaluate the association between abnormalities of the lesser tuberosity and subscapularis tendon lesions. MATERIALS AND METHODS Cortical irregularities and cysts of the lesser tuberosity were evaluated on radiographs and MR images in 70 patients: 31 with normal subscapularis tendons and 39 with subscapularis tendon tears. These imagi...

Subscapularis tendon tears are a well-established cause of shoulder pain. The objective of the current study was to evaluate the associated shoulder pathology in patients with full-thickness subscapularis tendon tears using magnetic resonance imaging. Forty-seven magnetic resonance imaging studies taken between 2008 and 2009 with a diagnosis of full-thickness subscapularis tendon tears were rev...

The subscapularis tendon, coracohumeral ligament, and transverse humeral ligament are all believed to contribute to biceps tendon stability within the bicipital groove. In order to examine the relative contribution of these soft tissue structures to proximal biceps tendon stability, 11 fresh frozen cadaveric shoulder specimens were prepared and mounted onto a custom jig. A three-dimensional dig...

The purpose of this study was to examine the accuracy of physical examination in the detection of subscapularis tendon tears and compare it with the gold standard of arthroscopy to determine whether clinical examination can reliably predict the presence of subscapularis tendon tears. This was a retrospective analysis of 52 patients (52 shoulders) who underwent arthroscopic subscapularis tendon ...
