We describe the results of Copeland surface replacement shoulder arthroplasty using the mark III prosthesis in patients over 80 years of age. End-stage arthritis of the shoulder is a source of significant pain and debilitating functional loss in the elderly. An arthroplasty offers good relief of pain and may allow the patient to maintain independence. The risk-benefit ratio of shoulder replacem...

Successful total shoulder arthroplasty is, in part, dependent on anatomic reconstruction of the glenohumeral joint. The purpose of this study was to evaluate the post-operative anatomy of total shoulder arthroplasty with an anatomic implant design in patients with primary glenohumeral osteoarthritis and compare it to published normative anatomic measurements. Fifty-one patients (56 shoulders) w...

Glenoid component failure is the most common complication of total shoulder arthroplasty. Glenoid components fail as a result of their inability to replicate essential properties of the normal glenoid articular surface to achieve durable fixation to the underlying bone, to withstand repeated eccentric loads and glenohumeral translation, and to resist wear and deformation. The possibility of gle...

In the more than century-long history of shoulder arthroplasty, scientists have gone from primitive ivory designs to high-tech implants made rare metal alloys. Along way, surgeons and inventors faced challenges, mistakes, succeeded. This literature review reflects trends in development evolutionary changes endoprosthesis principles surgical treatment pathology, late 19th century present. paper ...

There are few reports in the literature of the diagnosis and treatment of the infected shoulder arthroplasty. Most deal with resection arthroplasty and two-stage exchange surgery. We present our results of one-stage exchange operation as treatment for the infected shoulder arthroplasty. Our group comprised 16 patients (ten men, six women) with 16 infected arthroplasties. By the time of follow-u...

BACKGROUND The aim of this study was to determine if agreement could be obtained on guidelines regarding the ideal minimum age for a reverse shoulder replacement, as well as on post-operative rehabilitation and restrictions imposed on patients having undergone this procedure. MATERIAL AND METHODS A two-round Web-based Delphi consensus study was undertaken. An international group of experts in...

Despite improvements in glenoid prosthesis design, materials and surgical techniques, complications related to the glenoid component continue to be a leading cause of failure after total shoulder arthroplasty. Although previously felt to be of little clinical significance, radiolucent lines around the glenoid prosthesis are now recognized as a sign of impending mid and long term fixation proble...
