重组合异种骨修复良性骨肿瘤术后骨缺损的疗效观察

目的：观察一种复合异种骨修复良性骨肿瘤手术切除后骨缺损的临床疗效。方法：重组合异种骨（RBX）治疗36例良性骨肿瘤手术后的骨缺损，其中男20例，女16例；年龄8～62岁，平均31岁。观察手术后的并发症及骨愈合情况。结果：获得随访32例，平均随访时间12个月，最短10个月，最长24个月。有一例并发术后感染，26例在第9个月经x线片和CT证实获得骨性愈合，在随访期内未发生肿瘤复发。结论：RBX是一种较为理想的骨缺损修复材料，对良性骨肿瘤术后骨缺损的修复具有较为可靠的疗效。

Therapeutic effects of recombination grafting of heterologous bone for repairing of postoperative bone defects of benign bone tumor

Objective: To study therapeutic effects of recombination heterologous bone grafting for repairing of postoperative bone defects of benign bone tumor.Methods:Thirty-six patients with postoperative bone defects of benign bone tumor were treated with recombination heterologous bone grafting.Among all 36 patients,20 were male,16 were female,with ages from 8 to 62 years,averagely 31 years.Postoperative complications and bone healing were observed.Results:Thirty-two patients were followed up from 10 to 24 months,with an average of 12 months.Postoperative infection occurred in 1 patient,and 26 patients obtained bone healing which were confirmed by X-ray and CT examination at 9th month after treatment.There were no tumor recurrence during follow-up period.Conclusion:Recombination of heterologous bone is an ideal method to repair bone defect,based on the present results that it was effective in repairing operative bone defect of benign bone tumor.
