After internal hemipelvectomy for malignant pelvic tumors, pelvic reconstruction is necessary for eventual weight bearing and ambulation. Non-vascularised, fibular grafts (NVFG) offer fast, and stable reconstruction, post- modified Enneking's type I and I/IV resection. This study aimed to evaluate the success of graft union and patient function after NVFG reconstruction. From 1996 to 2009, 10 NVFG pelvic reconstructions were performed after internal hemipelvectomy in four cases of chondrosarcoma, three of Ewing's sarcoma, and single cases of osteosarcoma, malignant peripheral nerve sheath tumour, and malignant fibrous histiocytoma. A key indication for internal hemipelvectomy was sciatic notch preservation confirmed by preoperative MRI. Operation time and complications were recorded. The mean follow-up was 31.1 months (range: 5 to 56), and lower limb function was assessed using the Musculoskeletal Tumour Society scoring system. Plain radiographs and/or computer tomography were used to determine the presence or absence of NVFG union.Introduction and aims
