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...

BACKGROUND AND AIM OF THE WORK Cuff tear arthropathy (CTA) is a well-defined  degenerative pathology  of the shoulder. When conservative treatments are unable to permit a good quality of life, the reverse shoulder arthroplasty (RSA) can guarantee a good restitution of range of motion, function and strength of the shoulder without pain. In this paper we show our clinical, functional and radiolog...

Shoulder replacement surgery has evolved dramatically since first attempted by P ean and Gluck and modernized by Neer. Interest in shoulder replacement surgery is growing globally and, in many countries, is the fastest growing market in joint arthroplasty surgery. In the coming year, over 57,000 replacements will be undertaken in the United States and over 4,000 in Australia. To a large extent,...

An anterior glenohumeral dislocation is a serious condition which can lead to soft tissue damage and substantial defects of the humeral head and glenoid. Disturbance of shoulder joint congruency and soft tissue balancing can lead to poor function and severe impairment in these patients [1]. Little is known about the results of shoulder arthroplasty for the treatment of fixed glenohumeral disloc...

Patient Specific Instruments (PSIs) are increasingly being used to improve the accuracy of surgical procedures, especially arthroplasty, where precise bone preparation and implant placement are critical in the procedure’s success (Farron et al., 2006; Favre et al., 2008). To the authors’ knowledge, arthroplasty PSIs have only been applied to traditional, highlyinvasive surgical approaches, such...

BACKGROUND AND PURPOSE Different results after shoulder arthroplasty have been found for different diagnostic groups. We evaluated function, pain, and quality of life after shoulder arthroplasty in 4 diagnostic groups. PATIENTS AND METHODS Patients with shoulder arthroplasties registered in the Norwegian Arthroplasty Register from 1994 through 2008 were posted a questionnaire in 2010. 1,107 p...

A painful shoulder presents challenges in examination, diagnosis and intervention for the physical therapist because of the complexity of the structures involved. A common cause of shoulder pain is shoulder impingement syndrome. This was first described as a condition in which the soft tissues of the subacromial space were chronically entrapped and compressed between the humeral head and the su...

The Comprehensive® Shoulder Solutions’ Modular Hybrid Glenoid from Biomet is a revolutionary design for replacement of the glenoid in total shoulder arthroplasty. It provides three outer pegs and three central peg options for surgical implantation. In vitro testing of the Modular Hybrid Glenoid resulted in mean axial pull-out peak loads ranging from 209 to 303 lbf, mean inferior/superior shear ...

OBJECTIVE The purpose of this article is to provide a review of the indications for shoulder arthroplasty, describe preoperative imaging assessment, present new and modified designs of shoulder arthroplasty, illustrate normal and abnormal postoperative imaging findings, and review key radiographic measurements. CONCLUSION Knowledge of the physiologic purpose, orthopedic trends, imaging findin...
