自体骨髓复合人工骨联合髂骨骨膜移植修复四肢难治性骨不连:与单纯骨膜移植及骨髓联合人工骨移植的比较

背景:自体骨髓富含诱导性和确定性骨祖细胞的惟一组织,是治疗骨不连的首选移植材料:保留一定成骨诱导活性的人工骨可为成骨细胞的长入提供支撑和支架作用;髂骨膜最厚、血循环丰富、取材容易,移植可改善局部动脉血供,对骨愈合具有促进作用.目的:利用自体骨髓复合人工骨联合髂骨骨膜移植治疗四肢难治性骨不连,并同单纯髂骨植骨等方法进行比较.方法:选择四肢难治性骨不连患者36例39肢,根据治疗方案分为3组,自体骨髓复合人工骨联合髂骨骨膜移植(联合组)19肢,自体骨髓移植联合人工骨(骨髓组)9肢,自体髂骨移植治疗(髂骨组)11肢.观察骨愈合时间、固定物取出1个月患肢功能评分和移植后X射线评分.结果与结论:39肢最终均达骨性愈合,均获随访,平均随访时间18.5个月.在骨愈合时间、固定物取出1个月患肢功能评分和移植后X射线评分方面,联合组疗效优于其他两组(P<0.05).提示自体骨髓复合人工骨联合髂骨骨膜移植治疗四肢难治性骨不连临床疗效优越.

Transplantation of artificial bone with autologous bone marrow combined with iliac periosteum for treatment of refractory bone nonunion in limbs Comparison to artificial bone with autologous bone marrow transplantation and simple iliac periosterum transpl

BACKGROUND: Autologous bone marrow is the only tissue that contains abundant osteoinductive osteogenitor cells and is the first-choice transplantation materials for treatment of bone nonunion. Artificial bone with osteoinductive capacity can provide a supporting effect for the in-growth of osteocytes. Iliac periosteum can be used for treatment of bone nonunion due to the advantages including abundant blood circulation, easy harvesting, and able to improve local arterial blood supply. BJECTIVE: To treat refractory bone nonunion in limbs using artificial bone with autologous bone marrow combined with iliac periosteum transplantation, and to compare the therapeutic efficacy to artificial bone with autologous bone marrow transplantation and simple iliac periosterum transplantation. METHOD: Thirty-nine refractory bone nonunion limbs from 36 patients were assigned to three groups: artificial bone with autologous bone marrow combined with iliac periosteum transplantation (combination group, n = 19), artificial bone with autologous bone marrow (bone marrow group, n = 9), and autologous iliac periosteum (iliac periosteum group, n = 11). The time for bone healing, limb function score 1 month after fixture removal, and postoperative X-ray score were evaluated. RESULTS AND CONCLUSION: All initial 39 limbs acquired bone union and were followed up for an average period of 18.5 months. The combination group yielded better therapeutic effects than the bone marrow group and the iliac periosteum group in terms of the time for bone healing, limb function score 1 month after fixture removal, and postoperative X-ray score (P < 0.05). These findings indicate that artificial bone with autologous bone marrow combined with iliac periosteum transplantation exhibits better clinical therapeutic effects in treatment of refractory bone nonunion in limbs.
