摘要:

背景:诸多研究已证实重组人骨形态发生蛋白2在骨形成及骨折愈合中发挥十分重要的作用,但单纯予以重组人骨形态发生蛋白2植入容易出现扩散和降解,无法对新骨形成予以持续性的影响。
目的:观察重组人骨形态发生蛋白2复合骨在兔腰椎中的融合效果。
方法:取30只新西兰大白兔,构建后路腰椎横突间植骨融合模型,随机均分为3组,分别在L5-6横突间植入自体髂骨、同种异体骨及重组人骨形态发生蛋白2复合骨(重组人骨形态发生蛋白2与同种异体骨复合物),植入后6周,进行大体观察、X射线检查及组织学观察。
结果与结论:重组人骨形态发生蛋白2复合骨组融合率、新生骨组织在总面积中所占百分比高于自体髂骨组、同种异体骨组(P < 0.05);重组人骨形态发生蛋白2复合骨组、自体髂骨组拉伸强度大于同种异体骨组(P < 0.05),前两组拉伸强度无差异。X射线显示3组植骨区均可见骨痂形成;组织学显示,自体髂骨组移植物已消失,形成大量软骨,有少量骨小梁,并有一定编织骨形成;同种异体骨组有较多的纤维组织包裹材料,有骨岛形成,有数量较少的骨小梁及软骨形成;重组人骨形态发生蛋白2复合骨组存在大量骨小梁和少量软骨,形成编织骨且有皮质骨形成。表明重组人骨形态发生蛋白2复合骨在兔腰椎中可以获得良好的融合效果。

Abstract:

BACKGROUND: Many studies have confirmed that recombinant human bone morphogenetic protein 2 plays a very important role in bone formation and fracture healing, but recombinant human bone morphogenetic protein 2 alone implanted is prone to diffusion and degradation, which is unable to play a persistent role in new bone formation.
OBJECTIVE: To explore the effect of recombinant human bone morphogenetic protein 2 composite bone in the rabbit lumbar fusion.
METHODS: Thirty New Zealand white rabbits were selected to make posterior lumbar intertransverse fusion models, and then were randomly divided into three groups, in which, L5-6 intertransverse implantation of autologous iliac bone, allogeneic bone and recombinant human bone morphogenetic protein 2 composite bone 
(recombinant human bone morphogenetic protein 2 and allogeneic bone complex) was done respectively. At 6 weeks after implantation, gross observation, X-ray examination and histological observation were performed.
RESULTS AND CONCLUSION: Fusion rate and percentage of new bone area were higher in the composite bone group than the autologous iliac bone and allogeneic bone groups (P < 0.05); the tensile strength was lower in the allogeneic bone group than the other two groups (P < 0.05), but there was no difference between these two groups except the allogeneic bone group. X-ray films showed callus formation in the implanted region of the three groups. In the autologous iliac bone group, a large amount of cartilage tissues formed along with a small amount of bone trabeculae and a certain amount of woven bones. In the allogeneic bone group, the implant was covered with a large amount of fibrous tissues, bone island was seen and there was also a small amount of bone trabeculae and cartilage tissues. In the composite bone group, a great amount of bone trabeculae and cartilage tissues were visible to form woven bone and cortical bone. These findings indicate that the recombinant human bone morphogenetic protein 2 composite bone can obtain good effect in the rabbit lumbar fusion.
