BACKGROUND It has been indicated that rotator cuff tears, especially large or massive ones, can cause suprascapular neuropathy. When such a diagnosis has been established, it is still unknown whether an arthroscopic release of the superior transverse scapular ligament during cuff repair can change the course of this neuropathy. METHODS/DESIGN This is a single-center, double-blinded randomized...

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 In the case of rotator cuff tears, the biceps pulley can be stressed by the unstable biceps tendon, and this can subsequently affect the stability of the subscapularis tendon. Therefore, it is important to distinguish between normal variations and lesions of the biceps pulley that affect anterosuperior lesions in cases of rotator cuff tears. METHODS From January 2002 through Novemb...

PURPOSE To compare preoperative non-contrast magnetic resonance imaging (MRI) with arthroscopy findings in diagnosing labral and rotator cuff tears. METHODS 86 men and 60 women aged 21 to 70 (mean, 52) years underwent non-contrast MRI before arthroscopic operations on the glenohumeral joint. Slices were made in a transverse, parasagittal, and paracoronar orientation. The sequences used were T...

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...

The management of irreparable rotator cuff tears remains challenging. Since its introduction by Mihata in 2012, superiorcapsule reconstruction (SCR) has grown in popularity at an astonishingly rapid rate. The aim of this article is to providea comprehensive review of the available literature, in order to highlight what has so far been published on SCR,covering all aspects including biomechanica...

Full-thickness tears to the rotator cuff can cause severe pain and disability. Untreated tears progress in size and are associated with muscle atrophy and an infiltration of fat to the area, a condition known as "fatty degeneration." To improve the treatment of rotator cuff tears, a greater understanding of the changes in the contractile properties of muscle fibers and the molecular regulation ...

028 Clinical results of arthroscopic repair for incomplete rotator cuff tear Takayuki Sugihara, Tokyo Medical and Dental University Hospital To clear the merits of arthroscopic surgery, we investigated the clinical outcome of the arthroscopic repair on incomplete rotator cuff tears. Thirteen shoulders with incomplete rotator cuff tears were treated by arthroscopy from 2000 to 2005. There were 9...

The purpose of this study was to investigate the characteristics of rotator cuff tears and the clinical outcome of rotator cuff repair in patients under 50 years of age. Sixty-eight patients (72 shoulders) aged < 50 years, who underwent repair of rotator cuff tears were evaluated. We analyzed the cause of injury, tear size, time from symptom onset to surgery, and rate that patients returned to ...

INTRODUCTION: Rotator cuff tears (RCT) are the most common tendon injury seen in orthopedic patients. Although small tears are amenable to arthroscopic repair, massive RCT repairs can result in re-tears and poor clinical outcomes. Muscle atrophy and fatty infiltration in rotator cuff muscles are major complications of chronic massive RCT and are thought to be among the factors responsible for t...
