Following bone tumour resection, lower limb reconstruction results in leg-length discrepancy in skeletally immature patients. Previously, minimally invasive endoprostheses have been associated with a high risk of complications including joint stiffness, nerve injury, aseptic loosening and infection. The purpose of this study was to examine the outcome of the Stanmore non-invasive extendible endoprostheses used in our institution between 2002 and 2009 and compare them with implants used in the past. Fifty-five children with a mean age of 11.4 years (5 to 16) underwent limb reconstruction with thirty-three distal femoral, two total femoral, eight proximal femoral and twelve proximal tibial implants. Forty-six endoprostheses were lengthened in clinic without anaesthesia using the principle of electromagnetic induction. Patients were assessed using the Musculoskeletal Tumour Society Score (MSTS) and the Toronto Extremity Salvage Score (TESS).Introduction

Primary bone tumours of the distal radius are rare, while it remains the third commonest site for primary lesions and recurrences of Giant Cell Tumours (GCT). The functional demands on the hand make reconstruction of the wrist joint following the excision of distal radius, particularly challenging. A single-centre retrospective study, reporting the functional and oncological outcomes of six patients (4 males, 2 females - mean age of 53 (22 to 79)) who underwent a custom-made endoprosthetic replacement of the distal radius with arthrodesis at our institution, during 1999 - 2010. Five patients were diagnosed with primary bone sarcoma of the distal radius (4 GCTs, 1 osteosarcoma) and another had a metastatic lesion from a primary renal cell carcinoma. The diagnosis was confirmed by needle biopsy in all cases. We assessed the patients' functional outcomes using the Musculoskeletal Tumour Society scoring system (MSTS) and the Toronto Extremity Salvage Score (TESS).Introduction
