Background: For surgical treatment of symptomatic partial rotator cuff tears, 2 repair techniques, i.e., arthroscopic trans-tendon repair and arthroscopic repair after conversion to full thickness tear, were widely used and satisfactory clinical outcomes have been reported. However, no study has seen for the direct evaluation of repair integrity after arthroscopic rotator cuff repair using seco...

Full-thickness rotator cuff tear associated with gleno-humeral anterior dislocation is a rare injury in patients younger than 40 years of age. We here report a case of recurrent anterior shoulder dislocation with glenoid bone loss and concurrent irreparable rotator cuff tear in a young patient. This is, to the best of our knowledge, the first such case reported in the literature. We also discus...

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...

PURPOSE Rotator cuff tear is the most common shoulder disease in patients with shoulder problems, but its prevalence is not well known. METHODS We performed a health care check-up of locomotive organs in 664 residents (21.3% of the population) in one village. Ultrasonography on bilateral shoulders was performed in all the participants. RESULTS One hundred and forty seven out of 664 subjects...

BACKGROUND It has been theorized that degenerative rotator cuff tears most commonly involve the supraspinatus tendon, initiating at the anterior portion of the supraspinatus insertion and propagating posteriorly. The purposes of this study were to determine the most common location of degenerative rotator cuff tears and to examine tear location patterns associated with various tear sizes. MET...

INTRODUCTION: Rotator cuff tear is one of the common shoulder disorders and surgical repair is very effective for the improvement of shoulder functions. Current surgical technique for rotator cuff tear is an arthroscopical repair or a mini-open repair. Selection of surgical technique should be determined by the appropriate patient’s selection based on the pathology of the rotator cuff tear. Mag...

Background/objective Rotator cuff tears are common shoulder injuries. Various forms of rotator cuff tears are observed by arthroscopy. Inverted flap tears of the rotator cuff, however, also occur. The aim of the present study was to determine the preoperative characteristics of inverted torn cuffs and clinical outcomes after arthroscopic repair. Methods Seventeen patients (10 men, 7 women; me...

Background and purpose - There is a need to understand the reasons why a high proportion of rotator cuff repairs fail to heal. Using data from a large randomized clinical trial, we evaluated age and tear size as risk factors for failure of rotator cuff repair. Patients and methods - Between 2007 and 2014, 65 surgeons from 47 hospitals in the National Health Service (NHS) recruited 447 patients ...

Massive rotator cuff tears are particularly challenging to treat and severely limit the function of the shoulder. Compared with a small rotator cuff tear, massive tears are more unpredictable and usually present with low tendon quality. When performing an anatomical repair of the rotator cuff, the surgical treatment is often associated with failure of the construct. An alternative procedure tha...
