Abstract:
BACKGROUND:The prognosis of chondrosarcoma is closely associated with tumor location, size, removal methods and biological characteristics. OBJECTIVE:To explore the choice of reconstruction materials for bone defects after chondrosarcoma resection based on the retrospective analysis of different resection methods. METHODS:We retrospectively analyzed clinical data from 82 cases of chondrosarcoma who had received hondrosarcoma resection at the Department of Orthopedics, Changzhen Hospital of Second Military Medical University from January 1999 to January 2010. Al the involved patients were confirmed pathological y as having chondrosarcoma, including 51 males and 31 females, with a mean age of 39.8 years (range, 15-68 years). Chondrosarcoma was found in the pelvis (n=26), spine (n=19), femur (n=19), tibia and fibula (n=8), and shoulder (including the humerus) (n=12). Preoperative X-ray, MRI or CT was taken as wel as ECT. Clinical data, resection methods, and fol ow-up results were col ected for multivariate analysis to screen the possible prognostic factors of chondrosarcoma. RESULTS AND CONCLUSION:For chondrosarcoma, different types of resection result in a quite difference in recurrence rates, metastasis and mortality rates. The initial resection which is done outside the boundaries can significantly reduce the recurrence rate, metastasis rate and mortality. Autogenous bone, al ograft bone, and prosthetic reconstruction materials are effective for functional reconstruction. Autologous bone graft is limited clinical y because of its limited sources and complications at donor site. Al ograft or prosthetic reconstruction of bone defects is an effective method. Limited number of clinical cases reported makes it difficult to determine the pros and cons of different reconstruction materials. The need for reconstruction depends on the defect site and size, and reconstruction method depends on the type of resection. The important criteria for the choice of reconstruction materials include both form and functional repair of bone defects, chondrosarcoma type and the patient’s request.
