The purpose of this study was to determine the concentrations of cobalt, chromium, and molybdenum in the serum of paediatric tumour patients after fixed hinge total knee arthroplasty. Further, these metal ion levels were compared with serum metal ion levels of patients with other orthopaedic devices such as hip and knee prostheses with metal-on-metal or(More)
The aims of this study were to evaluate the incidence of local argyria in patients with silver-coated megaprostheses and to identify a possible association between argyria and elevated levels of silver both locally and in the blood. Between 2004 and 2011, 32 megaprostheses with silver coatings were implanted in 20 female and 12 male patients following(More)
Reconstruction with massive bone allograft and autologous vascularised fibula combines the structural strength of the allograft and the advantages of fibula's intrinsic blood supply. We retrospectively analysed the outcome of twelve patients (4 male, 8 female) who received reconstruction with massive bone allograft and autologous vascularised fibula after(More)
Although the diagnostic algorithm of a suspected bone or soft tissue tumour, as well as the biopsy itself, are well defined, avoidable errors still happen. Major flaws might lead to unnecessary tissue contamination resulting in amputations or recurrences. In the current review we will focus in particular on biopsy guidelines and possible biopsy-related(More)
BACKGROUND Metal-on-metal hip resurfacing is an alternative to metal-on-metal total hip arthroplasty, especially for young and physically active patients. However, wear which might be detected by increased serum ion levels is a matter of concern. METHODS The aims of this preliminary study were to determine the raise of metal ion levels at 2-years(More)
Primary malignant bone tumours and soft tissue sarcomas of the chest wall are exceedingly rare entities. The aim of this study was a retrospective two-institutional analysis of surgical therapy with respect to the kind and amount of the resection performed, the type of reconstruction and the oncological outcome. Between September 1999 and August 2010 31(More)
We describe the outcome in a series of patients treated for metastatic peri-actetabular and iliac bone destruction using a modified technique of Harrington’s procedure. Between 2006 and 2012, nine patients with a mean age of 62.2 years (42–75 years) were treated using a modified Harrington technique. Thereby, total hip replacement implants augmented by two(More)
Metal-on-metal hip resurfacing has become a widespread procedure, especially in young, physically active patients. Pseudotumor is a new complication that can occur after hip resurfacing and metal-on-metal total hip arthroplasty (THA). This article presents a case of a 37-year-old woman who underwent metal-on-metal resurfacing of the left hip for symptomatic(More)
GRUNDLAGEN: Weichteilsarkome (WTSA) sind seltene mesenchymale Tumore des Stütz- und Bewegungsapparates mit einer hohen Inzidenz an primären Fehldiagnosen und Therapie außerhalb bestehender Richtlinien. Im Zuge dieser retrospektiven Kohortenanalyse wurde der Einfluss von primär inadäquater chirurgischer Therapie vor Transferierung an ein Tumorzentrum(More)
Die Ziele der multimodalen und interdisziplinär zu planenden Therapie von Knochenmetastasen sind die Wiederherstellung bzw. der Erhalt der Mobilität der Betroffenen, eine weitgehende Schmerzfreiheit sowie eine adäquate Lebensqualität. Gemeinsam mit weiteren Disziplinen wie Strahlentherapie und Onkologie ist ein individueller Therapieplan zu erstellen. Da(More)
