INTRODUCTION The literature review revealed that nowadays only about 15 cases of bilateral shoulder dislocation associated with the fracture of the upper end of the humerus have been published. The triad of lesional mechanism designated by the triple syndrome E composed of epilepsy, electrocution, and external trauma was the circumstances noted in which these fractures dislocations occur with m...

Periprosthetic joint infection (PJI) is one of the most frequent reasons for painful shoulder arthroplasties and revision surgery of shoulder arthroplasties. Cutibacterium acnes (Propionibacterium acnes) is one of the microorganisms that most often causes the infection. However, this slow growing microorganism is difficult to detect. This paper presents an overview of different diagnostic test ...

Primary hemiarthroplasty of the shoulder is an accepted procedure to treat complex proximal humeral fractures. The goal of this study was to assess the functional outcome in patients treated with hemiarthroplasty using a custom offset shoulder prosthesis, either for an acute four-part fracture of the proximal humerus or following failed primary treatment of a complex humeral fracture. Thirty se...

BACKGROUND The latest generation of shoulder arthroplasty includes canal-sparing respectively stemless designs that have been developed to allow restoration of the glenohumeral center of rotation independently from the shaft, and to avoid stem-related complications. The stemless prosthesis design has also recently been introduced for use in reverse arthroplasty systems. METHODS We systematica...

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...

BACKGROUND The Zweymüller stem design has proven long-term stability with a 20-year survival rate of over 90 %. Primary stability necessitates implant-bone micromotions below 150 μm, otherwise bony ingrowth is negatively influenced. METHODS Using fresh paired human femurs, we investigated a modification of the Zweymüller-type stem design with reduced proximal lateral shoulder in reference to ...

Limb salvage procedures in primary bone tumours of the scapula offer attractive prospects regarding function and aesthetics. What procedure depends mainly on the site/extension, stage/diagnosis. In scapular resections the glenoid plays the key role. This retrospective study shows single centre Results regarding outcome. Methods: From October 1983–February 1998 thirty-three patients presenting w...

Only in Japan, there are about 82,000 upper limb amputees (Ministry of Health, Labour and Welfare, 2005). Using upper limb prostheses could restore the function for them, thus improve significantly the quality of their activities of daily living [ADL]. Compared with below-elbow prostheses, shoulder prostheses are left behind in their development, due to high degrees of freedom [DOF] required, w...

The combination of an irreparable tear of the rotator cuff and destructive arthritis of the shoulder joint may cause severe pain, disability and loss of independence in the aged. Standard anatomical shoulder replacements depend on a functioning rotator cuff, and hence may fail in the presence of tears in the cuff. Many designs of non-anatomical constrained or semi-constrained prostheses have be...
