We have undertaken a prospective clinical and radiological analysis of 124 shoulder arthroplasties (113 patients) carried out for osteoarthritis. The clinical results showed improvement in the absolute Constant score and the American Shoulder and Elbow Surgeons score of 22 and 43, respectively. Both were statistically significant (p < 0.001). There was no significant difference in the scores af...

Background: Successful repair of a torn rotator cuff may prevent progression to rotator cuff arthropathy. However,previous studies have shown a substantial rate of failure after rotator cuff repair and characteristics of surgicallyrepaired rotator cuffs that go on to shoulder arthroplasty have not been fully elucidated. The purpose of this study wasto determine the patient cha...

Infection in the setting of shoulder arthroplasty can result in significant pain, loss of function, and the need for additional surgery. As the use of shoulder arthroplasty increases, the medical and economic burdens of periprosthetic joint infection increase as well. The ideal management of infected shoulder prostheses has not been established. This report describes 9 patients from a single in...

 Abstract  Background: In the recent decade, many primary total knee arthroplasties have  been carried out in Iran and the number of revision cases is expected to rise with the  aging population. The aim of this study was to report the outcome of revision surgery  in the country and make a comparison between the outcome of revision and that of  the primary arthroplasty.  Methods: Retrospectivel...

The results of anatomic total shoulder arthroplasty and reverse shoulder arthroplasty have previously been reported separately. Although the indications differ, scenarios exist in which a patient may have a total shoulder arthroplasty on 1 shoulder and a reverse shoulder arthroplasty on the contralateral shoulder.Between 1992 and 2009, twelve patients underwent bilateral sequential primary shou...

The shoulder is a fascinating joint. The combination of mobility and stability of the shoulder allows us to position the upper extremity in space so that we may accomplish a large variety of functions. A wide array of pathological entities affect the shoulder, ranging from arthritis to instability and including the rotator cuff, scapular muscles and other joints in addition to the glenohumeral ...
