目的 介绍自体骨膜骨髓复合移植修复少儿良性骨肿瘤切除后骨缺损的方法。方法 抽取自体髂骨骨髓 ,自然形成凝块后植入骨缺损处 ,自体胫前骨膜切成 1～ 2mm2 邮票状 ,均匀植入骨髓凝块中。结果 随访 4～ 10个月 ,术后 1个月新生骨形成 ,术后 3～ 4个月 14例骨缺损处新生骨骨密度与周围骨组织一致 ,术后 4个月恢复正常的关节功能和肢体负重功能。结论 自体游离骨膜骨髓复合移植 ,成骨能力强 ,方法简便 ,是治疗骨肿瘤切除后骨缺损的有效方法
Objective To introduce a method of autologous periosteal bone marrow transplantation for repairing bone defects after resection of benign bone tumors in children. Methods The bone marrow of autologous iliac bone was extracted and naturally clot was implanted into the bone defect. The anterior tibial periosteum was cut into 1 ~ 2mm2 stamps and uniformly implanted into the bone marrow clot. Results The patients were followed up for 4 to 10 months. The new bone was formed at 1 month after operation. The bone density of newborn was consistent with that of the surrounding bone in 14 cases of bone defects at 3 to 4 months after operation. The normal joint function was recovered at 4 months after operation. Body weight function. Conclusion Autologous free periosteal bone marrow transplantation, osteogenic ability, simple method, is an effective method for the treatment of bone defects after resection of bone tumor
