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...

In an effort to increase the immediate strength of a rotator cuff repair and to simulate the standard open reconstruction with its effective suture fixation, we have developed a novel technique for suture anchor reconstruction of the rotator cuff. The technique, termed mattress double anchor (MDA), is simple and adaptable. It makes use of 2 suture anchors that are placed independently and then ...

The diagnosis of chronic lesions of the rotator cuff is challenging. We have developed a new index to improve the sonographic diagnosis of chronic tears of the cuff. In a pilot study, we examined 50 asymptomatic healthy volunteers by ultrasound to establish the diameter of the rotator cuff in relation to the tendon of the long head of biceps. Subsequently, the index was calculated in 64 patient...

PURPOSE A review was conducted to synthesise the available research literature on the pathogenesis of rotator cuff tendinopathy. RELEVANCE Musculoskeletal disorders of the shoulder are extremely common, with reports of prevalence ranging from one in three people experiencing shoulder pain at some stage of their lives to approximately half the population experiencing at least one episode of sh...

BACKGROUND/AIMS The rate of healing failure after surgical repair of chronic rotator cuff tears is considerably high. The aim of this study was to investigate the function of the zinc finger transcription factor early growth response 1 (EGR1) in the differentiation of tendon stem cells (TSCs) and in tendon formation, healing, and tendon tear repair using an animal model of rotator cuff repair. ...

PURPOSE The aim of the present study was to investigate whether coracoacromial arch angle is a predisposing factor for rotator cuff tears. METHODS Shoulder magnetic resonance imaging (MRI) examinations of 40 patients having shoulder arthroscopy due to rotator cuff tears and 28 patients with normal MRI findings were evaluated retrospectively. Acromio-humeral distance, coraco-humeral distance, ...

QUESTION During isometric shoulder adduction in normal subjects, do the rotator cuff muscles activate more than other shoulder muscles? Are the activation patterns influenced by shoulder abduction angle or load? DESIGN A within-participant, repeated measures experimental study. PARTICIPANTS 15 healthy adults. INTERVENTION Participants performed an isometric adduction exercise at 30°, 60°,...

PURPOSE The purpose of this report is to describe a new full-thickness tear pattern of the posterosuperior rotator cuff with reversal healing. We describe the specific radiologic signs associated with this tear pattern and the arthroscopic rotator cuff repair technique. MATERIALS AND METHODS A prospective radiologic and clinical study collected all patients with a magnetic resonance imaging a...
