The treatment of complex humeral fractures or fracture-dislocations presents several challenges. Late complications such as malunion, avascular necrosis, or nonunion are frequent and often lead to articular incongruence. Patients can be severely handicapped, presenting with considerable pain, stiffness, and important functional impairment. Stiff shoulders(More)
Auch ausgeprägte extrinsische Ellenbogengelenksteifen sind mit einer offenen Arthrolyse effektiv und mit zufriedenstellenden Ergebnissen zu behandeln. Eine sorgfältige präoperative Planung zur Beurteilung einer möglichen Gelenkbeteiligung und Entscheidung hinsichtlich des zu wählenden Zugangswegs ist von entscheidender Bedeutung. In den meisten Fällen ist(More)
INTRODUCTION Our purpose was to evaluate if, in case of aseptic glenoid loosening and failure in anatomical total shoulder arthroplasty (TSA), revision by a reverse shoulder arthroplasty (RSA) is a reliable therapeutic option. METHODS Retrospective multicenter cohort study of 37 consecutive anatomical TSA revised by RSA for aseptic glenoid loosening or(More)
We retrospectively analysed the clinical results of 30 patients with injuries of the sternoclavicular joint at a minimum of 12 months' follow-up. A closed reduction was attempted in 14 cases. It was successful in only five of ten dislocations, and failed in all four epiphyseal disruptions. A total of 25 patients underwent surgical reduction, in 18 cases in(More)
Radial head prostheses are indicated for treatment of complex radial head fractures not amenable for fixation. After the initial experience with silastic implants, metallic or pyrocarbon arthroplasty have been used for 20 years. Little is known about complications related to these implants. Main complications are related to loosening whether they are(More)
INTRODUCTION The aim of our study was to evaluate the results of surgical treatment of clavicle non-union after failure of conservative treatment. Our hypothesis was that stable fixation with bone graft derived from local bone stock (fracture site) or the iliac crest was essential to achieve bone union. MATERIAL AND METHODS Twenty-one patients with a(More)
BACKGROUND Reverse shoulder arthroplasty (RSA) provides an alternative for shoulder girdle reconstruction after wide transarticular resection of the proximal humerus for malignant tumor. The aim of this study was to evaluate midterm outcomes of this therapeutic option. METHODS Ten patients with RSA were included and reviewed with 24 months of minimum(More)
Intraosseous leiomyoma is an exceedingly rare tumor, with about 15 cases in the literature. Gradually worsening nonspecific pain is the main manifestation. A unilocular or multilocular radiolucency with a rim of sclerosis is seen on standard radiographs. The findings may simulate nonossifying fibroma of a metaphysis or histiocytofibroma of the pelvis.(More)
INTRODUCTION Arthrodesis of the knee, particularly in infectious situations, can be achieved using either an external fixator or an intramedullary device. The objective of this study is to report the clinical, functional, and radiographic outcomes of a continuous series of 19 cases of knee arthrodesis using a customized modular intramedullary nailing(More)
Proximal humerus fractures (PHF) are osteoporotic fractures that affect women over 70 years of age. Like fractures of the femoral neck they have become a public health concern. As the population ages there is an increase in the number of people in poor general condition with an increased risk of falls on fragile bones. The incidence of these fractures has(More)
