OBJECTIVE The purpose of this study was to determine whether occult bony injuries or other characteristic MR abnormalities are frequent in patients suspected of having traumatic tears of the rotator cuff. SUBJECTS AND METHODS MR arthrography of the shoulder was performed in 24 consecutive patients with suspected traumatic tears of the rotator cuff. MR findings were analyzed with regard to abn...

Partial-thickness rotator cuff tears are not a single entity; rather, they represent a spectrum of disease states. Although often asymptomatic, they can be significantly disabling. Overhead throwing athletes with partial-thickness rotator cuff tears differ with respect to etiology, goals, and treatment from older, nonathlete patients with degenerative tears. Pathogenesis of degenerative partial...

Objective: Few investigators have evaluated whether ultrasonography operated by a surgeon during a patient’s clinic visit is capable of obtaining a similar degree of accuracy as magnetic resonance imaging in regard to the diagnosis of rotator cuff tears and lesions of the biceps tendon. The purpose of this study was to clarify the accuracy of in-office ultrasonography for the diagnosis of rotat...

Overuse injuries of the rotator cuff are a significant source of pain and morbidity.1 Despite an aging population and documented associations between rotator cuff tears and increasing age, the pathogenesis of rotator cuff tendinopathy remains poorly understood.1-9 The natural history of rotator cuff tears is unfavorable, as these lesions fail to spontaneously heal and progress in size over time...

BACKGROUND The study aimed to evaluate of the role of high-resolution ultrasound and magnetic resonance imaging in patients with shoulder pain. MATERIAL/METHODS This prospective study included 50 patients referred for ultrasound and MRI because of shoulder pain. All patients were examined clinically, followed by radiography of the affected shoulder. High-resolution ultrasound examination of t...

Background Many patients with rotator cuff tears suffer from nocturnal shoulder pain, resulting in sleep disturbance. Purpose To determine whether rotator cuff tear size correlated with sleep disturbance in patients with full-thickness rotator cuff tears. Study Design Cross-sectional study; Level of evidence, 3. Methods Patients with a diagnosis of unilateral full-thickness rotator cuff t...

Anatomic factors, such as a hooked acromion, have been associated with rotator cuff disorders. Orientation of the glenoid relative to the scapula has been implicated in shoulder instability, but it has not been linked to rotator cuff disorders. The purpose of the current study was to test the hypothesis that superior inclination of the glenoid is associated with full-thickness rotator cuff tear...

The time-course covered by the original definition of scapulo-humeral periarthritis suggested by Duplay through the more recent term of subacromial impingement syndrome coined by Neer, follows the identification of the pathogenetic mechanisms leading to chronic subacromial impingement and degenerative tears of the rotator cuff. The Authors recall the functional-anatomic development evolution of...

We have studied cellular and vascular changes in different stages of full thickness tears of the rotator cuff. We examined biopsies from the supraspinatus tendon in 40 patients with chronic rotator cuff tears who were undergoing surgery and compared them with biopsies from four uninjured subscapularis tendons. Morphological and immunocytochemical methods using monoclonal antibodies directed aga...

OBJECTIVE To assess the diagnostic performance of MR arthrography in the diagnosis of the various types of partial-thickness rotator cuff tears by comparing the MR imaging findings with the arthroscopic findings. MATERIALS AND METHODS The series of MR arthrography studies included 202 patients consisting of 100 patients with partial-thickness rotator cuff tears proved by arthroscopy and a con...
