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...

Anterosuperior rotator cuff tears involve the subscapularis tendon, supraspinatus tendon, and rotator interval. The long head of the biceps is usually affected and unstable in these complex lesions. Arthroscopic repair of anterosuperior rotator cuff tears often consists of 2 different procedures. Whereas the subscapularis tendon is reconstructed under intra-articular visualization, the supraspi...

BACKGROUND Rotator-cuff pathology is the most common cause of pain and disability in the shoulder. Examining the combined effect of biological and societal factors on disability would potentially identify existing differences between men and women with rotator cuff pathology which would help to provide suggestions for better models of care. Purpose of this study was to determine the overall dif...

Magnetic resonance imaging (MRI) has been playing an increasingly important role in the spinal trauma patients due to high sensitivity for detection of acute soft tissue and cord injuries. More and more patients are undergoing MRI for spinal trauma in the emergency settings, thus necessitating the interpreting physicians to be familiar with MRI findings in spinal trauma. In this pictorial revie...
