In this article, we document the history of the shoulder prosthesis in cases of gleno-humeral arthropathy with severely damaged peri-articular structures, in particular, the rotator cuff. Charles Neer was the fi rst to search for a solution to this diffi cult problem and his work encouraged others including Paul Grammont to develop his revolutionary principles applied to the reverse shoulder pr...

Background Shoulder arthroplasty, in its different forms (hemiarthroplasty, total shoulder arthroplasty and reverse total shoulder arthroplasty) has transformed the clinical outcomes of shoulder disorders. Improvement of general clinical outcome is the result of stronger adequacy of the treatment to the diagnosis, enhanced surgical techniques, specific implanted materials, and more accurate fol...

BACKGROUND Proximal humeral fractures in elderly patients present with severe comminution and osteoporotic bone quality. Reverse shoulder arthroplasty has lately been proven beneficial in treating patients with complex proximal humeral fractures. The above technique is recommended and has better results in elderly than in younger individuals. METHODS We performed a literature search in the da...

The reverse shoulder prosthesis is designed for the treatment of glenohumeral arthritis with irreparable cuff arthropathy. Although it has given good short term results the prosthesis is not free of complications. In this case report we describe an implant-related complication.

Shoulder replacement surgery is a reliable procedure that provides predictable results in patients with all types of glenohumeral arthritis. When performed by an experienced surgeon for the right indications, and with appropriate physical therapy, dramatic improvements in pain and function are seen in the majority of patients. With the recent availability of the reverse prosthesis, even patient...

Total Shoulder Arthroplasty (TSA) is the process of replacing damaged ball and socket joint in shoulder with a prosthesis made polyethylene metal components. After this procedure, intervention may be required as result damage to prosthesis, except for need an examination regarding at certain periods. If patient does not have information about model manufacturer treatment delayed. Artificial int...

We present a case of a postradiation soft tissue sarcoma of the shoulder in a patient with a hemiarthroplasty of the shoulder. Initially the patient was treated for an infection of the hemiarthroplasty but subsequent removal of the loose prosthesis and biopsy revealed the presence of a malignant tumour.

Current reverse total shoulder arthroplasty prosthesis designs do not permit offset of the humerus in the sagittal plane. Posteriorly shifting the humerus has the theoretical benefit of lengthening the infraspinatus and teres minor muscles and their external rotation moment arms, thereby improving the tension and efficiency of each external rotator and subsequently requiring each muscle to prod...

TEACHING OBJECTIVES: To review the current concepts of shoulder arthroplasty. To review the normal post-operative appearance of shoulder arthroplasty including materials, design, and function. To review the imaging appearance of common complications. CONTENTS: Prosthesis material, design, and terminology Preoperative imaging assessment Normal post-operative imaging appearance Imaging findings o...

BACKGROUND Patients with disabling pain and loss of shoulder function with associated proximal humeral bone loss following shoulder arthroplasty have limited reliable treatment options. Our objective was to report the results, obtained as part of a prospective outcomes study, of the use of a reverse shoulder prosthesis-allograft composite in these patients. METHODS Between 2002 and 2005, 353 ...
