Salvage therapy by hemicortical excision and reconstruction for low-grade malignant bone tumour / 中南大学学报(医学版)

ABSTRACT

Objective: To treat low-grade limb malignant tumors with hemicortical excision and reconstruction of the defect with recycled pasteurized autogratf. Methods:From January 2005 to January 2011, 10 patients [age (27.0±6.5) years] suffering from low-grade limb malignant tumors were treated with hemicortical excision and reconstruction of the defect with recycled pasteurized autogratf7 were histopathologically diagnosed as parosteal osteosarcoma, and 3 as peripheral chondrosarcoma. According to the Enneking staging system, 8 were in Stage IA and 2 were in IB. Results:All the patients were followed-up for (50±23) months. All the patients had bony union at the last follow-up. The length of tumor bone resection was (9.5±2.7) cm, operation time was (150±45) min, intraoperative blood loss was (1000±350) mL, and drainage volume was (450±200) mL. hTe only fracture in the host bone during the operation was treated by internal ifxation. Local recurrence occurred in 1 patient was treated by a wide operative margin and reconstruction with a prosthesis. There was no distal metastasis. A ccording to the Enneking system, 9 patients had excellent results and 1 had good results. Conclusion:Hemicortical excision for low-grade limb malignant tumors is safe and effective.
