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...

BACKGROUND AND PURPOSE We describe the structural abnormalities in the painful shoulder of stroke survivors and their relationships to clinical characteristics. Method- Eighty-nine chronic stroke survivors with poststroke shoulder pain underwent T1- and T2-weighted multiplanar, multisequence MRI of the painful paretic shoulder. All scans were reviewed by one radiologist for the following abnorm...

BACKGROUND Six classification systems have been proposed for describing rotator cuff tears designed to help understand their natural history and make treatment decisions. PURPOSE To assess the interobserver variation for these classification systems and identify the method with the best interobserver agreement. STUDY DESIGN Cohort study (diagnosis); Level of evidence, 2. METHODS Six rotat...

Partial thickness rotator cuff tears are a common cause of pain in the adult shoulder. Despite their high prevalence, the diagnosis and treatment of partial thickness rotator cuff tears remains controversial. While recent studies have helped to elucidate the anatomy and natural history of disease progression, the optimal treatment, both nonoperative and operative, is unclear. Although the adven...

The goal of this study was to compare the accuracy of abduction-external rotation magnetic resonance arthrography (ABERMRA) with standard MRA in the diagnosis of intra-articular shoulder pathology.One hundred three consecutive patients undergoing preoperative direct MRA and subsequent arthroscopic examination were included in the study. Seventy-eight patients underwent standard MRA and 25 under...

BACKGROUND A familial predisposition to the development of rotator cuff tearing has been previously reported. Very little information exists on the development of global tendon dysfunction in patients with rotator cuff tears. The purpose of the current study was to determine the incidence of global tendon dysfunction as well as the need for surgery for tendon dysfunction in patients with rotato...

INTRODUCTION: Rotator cuff tears are a common condition, affecting approximately 50% of the population over the age of 60 [1]. The etiology of rotator cuff tears is not well understood, but it is widely believed that abnormal glenohumeral joint (GHJ) motion leads to subacromial impingement and the development of rotator cuff tears [2]. The treatment of rotator cuff tears is based implicitly on ...

The high retear rates after surgery for irreparable rotator cuff tears can be explained by the healing capacity potential of tendons and the native rotator cuff enthesis characterised by complex morphological structures, called direct insertion. Many experimental researches have focused on biologically augmenting the rotator cuff reconstruction and improving tendon-bone healing of the rotator c...

OBJECTIVE To describe shoulder disorders in patients evaluated by two shoulder and elbow surgeons. METHODS This cross-sectional study analyzed patients evaluated by two authors, excluding acute fractures and dislocations and patients with symptoms not involving the shoulder. Age and sex distribution was determined for the different diagnoses. RESULTS We evaluated 1001 patients. Mean age was...

BACKGROUND Long head biceps (LHB) degeneration in combination with rotator cuff tears can be a source of chronic shoulder pain. LHB tenotomy is an approved surgical procedure for pain reduction and improvement of joint function, however, the pathophysiology of LHB degeneration is not fully understood. In the literature, neoangiogenesis in tendon tissue has previously been shown to be associated...
