Vascularized Fibula Grafts for Reconstruction of Bone Defects after Resection of Bone Sarcomas. (12th May 2010) - Petersen, Michael Mørk
Abstract : We evaluated the results of limb-sparing surgery and reconstruction of bone defects with vascularized fibula grafts in 8 consecutive patients (mean age at operation 13.6 years (range 4.1–24.2 years), female/male = 6/2) with bone sarcomas (BS) (osteosarcoma/Ewing's sarcoma/chondrosarcoma= 4/3/1) operated on form 2000 to 2006. The bone defects reconstructed were proximal femoral diaphysis and epiphysis (n = 2 ), humeral diaphysis (n = 2 ), humeral proximal diaphysis and epiphysis (n = 1 ), femoral diaphysis (n = 1 ), ulnar diaphysis (n = 1 ), and tibial diaphysis (n = 1 ). One patient with Ewing's sarcoma had an early hip disarticulation, developed multiple metastases, and died 9 months after the operation. The remaining patients (n = 7 ) are all alive 50 months (range 26–75 months) after surgery. During the follow-up the following major complications were seen: 1-2 fractures (n = 4 ), pseudarthrosis (n = 2 ), and hip dislocation (n = 1 ). Limb-sparing surgery with reconstruction of bone defects using vascularized fibular grafts in BS cases is feasible with acceptable clinical results, but fractures should be expected in many patients.
