Tissue repairing and functional reconstruction in limb salvage operation of bone malignant tumors / 中国矫形外科杂志

ABSTRACT

[Objective]To discuss the significance of tissue repairing and functional reconstruction in treatment of extremity malignant tumors by allogeneic bone graft and replanting devitalized bone after malignant bone tumor resection. [Method]A retrospective study of 56 patients with malignant bone tumor was conducted, including 35 male patients and 21 female patients. The age was between 9 and 60, with an average of 18.Tumor in 9 cases was in the proximal hunerus, 30 in the distal femur, and 17 in the proximal cnemis.Thirty-two cases were osteogenic sarcoma,17 cases were chondroma sarcomatosum,3 cases were maligant giant cell tumor of bone and 4 cases were metastatic.Soft tissue was repaired and extremity function was reconstructed by adopting allogeneic bone graft and replanting devitalized bone. Extremity functions, bone healing conditions, and complication were estimated according to Mankin metheds.[Result]Among these 56 patients,results in 20(35.7%) were excellent,11(19.6%) were good,8(14.3%) were fair,17 (30%) were poor. The satisfactory rate was 70%.Thirty-eight patients survived for two years without tumor.Thirty patients survived for 5 years with the survival rate of 55%. Except local relapsed, the major complications were infection (4 cases), fracture (3 cases),collapse of articular facet (1 cases), and arthrocleisis (5 cases),with the infection rate of 7%.No internal fixation was broken.[Conclusion]For extremity malignant tumor, effective tissue repairing and functional reconstruction not only offer a limb-sparing effect, but also keep the limb in good function. This is an effective method for bone malignant tumor.
