The aim of this study was to report the results of three forms of reconstruction for patients with a ditsl tibial bone tumour: an intercalary resection and reconstruction, an osteoarticular reconstruction, and arthrodesis of the ankle. A total of 73 patients with a median age of 19 years (interquartile range (IQR) 14 to 36) were included in this retrospective, multicentre study.Aims
Methods
Local recurrence of Giant cell tumours of bone (GCT) is considered the main complication of surgical treatment (50%). Intra-lesional curettage with adjuvants like phenol or polymethylmethacrylate (PMMA) is recommended as initial treatment, decreasing the risk of recurrence. However, risk factors for local recurrence in skeletal GCT have not yet been firmly established and a golden standard for treatment remains controversial. Aim of this study is identification of risk factors for recurrence in GCT, specifically after intra-lesional curettage with or without adjuvants. In a retrospective single-institution study 191 patients treated for GCT between 1964 and 2009 were included. Mean follow-up was 111 months (range 12-415). The recurrence-free survival and hazards for different treatment strategies and various patient and tumour characteristics were determined.Introduction
Methods
The purpose of this study was to compare the outcome, complications and survival of the three most commonly used surgical reconstructions of the proximal humerus in adult patients after trans-articular tumour resection. Between1985 and 2005 thirty-eight consecutive proximal humeral reconstructions using either, allograft-prosthesis composite (n=10), osteoarticular allograft (n=13) or a modular tumour prosthesis (n=14), were performed in our clinic. Their mean follow-up was ten years (nine months to 25 years). Of these, twenty-seven were disease free at latest follow-up (Mean follow-up 16.8 years) and ten had died of disease (4.2 years). Complications and implant survival with revision surgery as end-point are presented for the total group of patients, functional scores for surviving patients only. The endoprosthetic group presented the smallest complication rate of 21%, compared to 40% in the allograftprosthesis- composite and 62% in the osteoarticular allograft group. Only one revision was performed in the endoprosthetic group, in a case of shoulder instability. Infection after revision (n=3), pseudoarthrosis (n=2), fracture of the allograft (n=3), and shoulder instability (n=4) were major complications of allograft use in general. Kaplan-Meier-analysis showed a significantly better implant survival for the endoprosthetic group (log-rank p=0.002). At final follow-up the MusculoSkeletal Tumour Society scores averaged at; 72% for the allograft-prosthetic-composite (n=7, mean follow-up 19 years), 76% for the osteoarticular allograft (n=3, 16 years), and 77% for the endoprosthetic reconstruction (n=10, 6 years) groups.Method
