BACKGROUND Magnetic resonance imaging (MRI) is considered to be a valuable tool for the diagnosis of rotator cuff tears in patients with severe glenohumeral osteoarthritis who are indicated for total shoulder arthroplasty (TSA). We determined the sensitivity, specificity, and positive predictive value of MRI in diagnosing rotator cuff tears in such patients. METHODS MRI reports of 100 patient...

The goal of rotator cuff repairs is to achieve high initial fixation strength, minimize gap formation, maintain mechanical stability under cyclic loading, and optimize the biology of the tendon-bone interface until the cuff heals biologically to the bone. We have seen an evolution in our approaches to fixing rotator cuff tears from open to mini-open to all arthroscopic. In our arthroscopic tech...

This is the second of a two-part article describing the various tests that have been used to examine the shoulder to find and treat problems in that area. Part I of this article (January/February 2003, pages 154-160) focused on tests used to examine rotator cuff abnormalities. This article attempts to clarify the tests of laxity, instability, and the superior labral anterior and posterior (SLAP...

Rotator cuff disease is one of the most prevalent musculoskeletal disorders treated by orthopaedic surgeons. Despite its prevalence, the natural history of the disease is not completely understood, which is critical to consider when making decisions on surgical and nonsurgical treatment of rotator cuff tears. This article reviews the most recent studies on the natural history of rotator cuff di...

this presentation features, modalities: plain radiographs, ct, mri, and ultrasound; arthroplasty; hardware loosening; suture anchor migration; avn, collapse, arthritis; rotator cuff repair; labral repair.

HYPOTHESIS We hypothesized that the prevalence of rotator cuff tears would be higher among individuals with poor posture, regardless of the presence of symptoms. METHODS The study initially comprised 525 residents of a mountain village who participated in an annual health check. Participants completed a background questionnaire, and physical examinations were performed to evaluate shoulder fu...

OBJECTIVE The purpose of the present study was to compare self-report and interview administration methods using the Western Ontario Rotator Cuff Index (WORC) and Disabilities of the Arm, Shoulder and Hand Questionnaire (DASH) in patients with rotator cuff disorders. METHODS Thirty male and female patients over 18 years of age with rotator cuff disorders (tendinopathy or rotator cuff tear) an...

Background Limited literature exists regarding the influence of rotator cuff tear morphology on patient outcomes. Purpose To determine the effect of rotator cuff tear pattern (crescent, U-shape, L-shape) on patient-reported outcomes after rotator cuff repair. Study Design Cohort study; Level of evidence, 3. Methods Patients undergoing arthroscopic repair of known full-thickness rotator cu...

Rotator cuff repairs are the most common procedures in shoulder surgery, but still show long-term retear rates of up to 70%. Nonanatomic reconstruction is one possible cause of repair failure. The rotator cuff histologically consists of 5 separate layers of which 2 are macroscopically identifiable: the superior or tendinous layer and the inferior or capsule-ligamentous layer. In case of rotator...

INTRODUCTION: Rotator cuff tears are a very common source of pain and loss of function of the shoulder. As arthroscopic instrumentation and repair techniques have evolved, many studies have demonstrated success in repairing rotator cuff tears using these arthroscopic techniques alone compared with an open repair method. Despite these successful clinical outcomes, both open and arthroscopic rota...
