Subscapularis is the most powerful muscle in the rotator cuff. A steep learning curve and constrained space anteriorly make the repair difficult. In massive tears of the rotator cuff, repair of the subscapularis initially makes the massive supraspinatus tear repairable. We present our technique to repair subscapularis and supraspinatus tear by double-row anchors in a knotless and tension-free m...

background: this study was done to determine the prevalence of publication misconduct among iranian authors. methods: data were collected through an email survey of corresponding authors of papers published in iranian journals indexed in scopus during 2009-2011. using the double list experiment, these individuals were indirectly questioned about committing one of the five misconducts including ...

Rotator cuff tears are common and are expected to present with increasing frequency as the population ages. Various techniques in surgical repair have been described to improve clinical outcomes. A arthroscopic transosseous-equivalent double row repair is believed to be superior, with improved tendon to bone contact area and reduced gap formation. In our series of 143 patients, with 76 undergoi...

INTRODUCTION Although various techniques can be used to repair gluteal tendon tears, the long-term outcome is unclear and published studies typically involve only a small number of patients. The goals of this study were to determine (1) if functional improvement can be obtained, (2) if the repairs are continuous based on MRI, and (3) which factors determine success. HYPOTHESIS Gluteus medius ...

When revising failed double-row and suture-bridge rotator cuff repairs medial failures represent a potential feature. In the presence of a compromised healing environment, patch augmentation becomes a logical adjunct from a mechanical and biological point of view. A reproducible step-by-step revision technique is described that reinforces the weak central cuff area with an absorbable synthetic ...

in order to find the most appropriate planting patter and cultivar of grain corn, an experiment was conducted in agriculture research station of jiroft and kahnooj, iran for two years in 2007 and 2008 as a split-plot experiment based on a randomized complete blocks design with three replications. the main plot was planting patter at four levels of normal planting (single-row on one furrow), dou...

BACKGROUND The reported rate of failure after arthroscopic rotator cuff repair has varied widely. The influence of the repair technique on the failure rates and functional outcomes after open or arthroscopic rotator cuff repair remains controversial. The purpose of the present study was to evaluate the functional and anatomic results of arthroscopic rotator cuff repairs performed with the doubl...

Single-row versus double-row repair of rotator cuff tears is currently a controversial topic. In this Level V article, we articulate why we believe that second-generation double-row repair techniques, which use bridging sutures to link the 2 rows of suture anchors together in a self-reinforcing manner, are producing superior clinical and biomechanical results.

The results of experimental studies free-convective heat transfer single-, double- and four-row bundles finned tubes without with an exhaust shaft are presented. It is shown that the inter-tube spacing significantly affects energy efficiency bundle. optimum 61 mm for single-row, about 70 double-row, over bundles. With increase number rows in bundle specific capacity increases, but rate its decr...
