Rotator cuff tears are common, especially in the fifth and sixth decades of life, but can also occur in the competitive athlete. Genetic differences may contribute to overall injury risk. Identifying genetic loci associated with rotator cuff injury could shed light on the etiology of this injury. We performed a genome-wide association screen using publically available data from the Research Pro...

PURPOSE To examine the prognostic indicators associated with outcome following rotator cuff surgery. METHODS A retrospective evaluation of records on 1120 shoulders (1067 patients) with rotator cuff tear treated by surgery was performed. Preoperative, intra-operative and postoperative factors were analysed by Kendall's Tau-b correlation analysis and logistic regression analysis. RESULTS Pos...

s everal intrinsic and extrinsic factors have been advoated in the pathogenesis of rotator cuff tears, but it is till unclear whether the origin of the tear is related to endon degeneration itself or induced by several morhologic changes. The purpose of this study is to deermine the relationship between the acromial coverge of the humeral head and the presence of a cuff ear. We evaluated 148 sh...

BACKGROUND There has been no report to date regarding retraction patterns of delaminated rotator cuff tears. The purpose of this study was to evaluate the incidence and tearing patterns of delamination and repair integrity after the dual-layer repair of delaminated cuff tears. METHODS/DESIGN A consecutive series of 64 patients with posterosuperior rotator cuff tears underwent arthroscopic rot...

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...

Suprascapular nerve and rotator cuff function are intimately connected. The incidence of suprascapular neuropathy has been increasing due to improved understanding of the disease entity and detection methods. The nerve dysfunction often results from a traction injury or compression, and a common cause is increased tension on the nerve from retracted rotator cuff tears. Suprascapular neuropathy ...

Introduction The long head of the biceps (LHB) tendon has different loading patterns in its intraand extra-articular regions. The intra-articular region is exposed to complex loads including tension, compression, shear, and frictional forces, while the extra-articular portion is subjected primarily to tensional loads. Previous studies have also shown that the intra-articular region has a more d...

Abstract Shoulder pain accounts for 16% of the musculoskeletal complaints and represents an important cause absenteeism work. Abnormalities rotator cuff, including tears, are frequently seen on imaging studies. Unfortunately, asymptomatic tears frequent, up to 60% in patients older than 60 years old; therefore clinical correlation is essential. New anatomical concepts new surgical techniques ha...

OBJECTIVE to evaluate the functional result from arthroscopic repair of rotator cuff injuries in patients with pseudoparalysis, defined as incapacity to actively raise the arm above 90°, while complete passive elevation was possible. METHODS we reevaluated 38 patients with a mean follow-up of 51 months (minimum of 24). We analyzed the pseudoparalysis reversion rate and the functional result o...

INTRODUCTION: Rotator cuff tears are a common cause of shoulder pain and disability. Surgical repair of the rotator cuff tears is effective for improvement of shoulder function. The long head of the biceps brachii (LHB) tendon has an important mechanism for humeral head stability and glenohumeral articulation. 1) Several lesions around the LHB tendon associated with rotator cuff tears are repor...
