摘要:

文题释义:
骨形态发生蛋白:一种分泌性的多功能蛋白,是转化生长因子β超家族的一员,通过诱导未分化间充质干细胞的迁移、增殖和分化,形成成骨细胞和成软骨细胞,从而促进骨愈合。
骨不连:在骨折之后没有骨愈合,需要在愈合之前进行额外的治疗。确定骨折是否为骨不连所需的时间长度尚未明确,一般认为骨折6个月内未完全愈合被定义为骨不连,但美国食品和药物管理局将其定义为9个月。


背景:骨形态发生蛋白具有强大的骨诱导特性,已被证实能够促进骨折、骨缺损等疾病的骨愈合。但目前国内外针对骨形态发生蛋白用于治疗骨不连的研究较少,并且各研究结果间存在争议,使得骨形态发生蛋白治疗四肢长骨骨不连的疗效尚不明确。

目的:通过Meta分析,系统评价骨形态发生蛋白相比自体骨移植治疗四肢长骨骨不连的优势和不足。

方法:计算机检索PubMed、Elsevier、Web of Science、Cochrane Library、CNKI及万方等数据库建库至2019年4月发表的文献,筛选出与骨形态发生蛋白治疗四肢长骨骨不连相关的随机或非随机临床对照研究,并对纳入的文献进行质量评价和数据提取,采用 Cochrane 系统提供的 RevMan5.1 软件对结局指标进行Meta分析。

结果与结论:①共纳入8篇文献,其中随机对照试验和非随机对照试验各4篇,多为30-124例的小样本量研究,共计613例骨不连患者,观察组采用骨形态发生蛋白或骨形态发生蛋白联合骨移植,对照组采用自体骨移植;②Meta分析显示:骨形态发生蛋白或骨形态发生蛋白联合骨移植与自体骨移植的术后愈合率、感染率、二次手术率比较差异无显著性意义(P > 0.05);骨形态发生蛋白联合骨移植与自体骨移植的术后功能优良率比较差异无显著性意义(P > 0.05);骨形态发生蛋白联合自体骨移植的平均愈合时间短于自体骨移植[WMD=-1.24,95%CI(-1.70,-0.79),P < 0.01];骨形态发生蛋白或骨形态发生蛋白联合骨移植的手术时间短于自体骨移植(P < 0.01);单独应用骨形态发生蛋白的术中出血量少于自体骨移植(P < 0.05);骨形态发生蛋白联合自体骨移植的治疗费用高于自体骨移植(P < 0.01);单独应用骨形态发生蛋白与自体骨移植的住院时间比较差异无显著性意义(P > 0.05);③结果表明骨形态发生蛋白能够为自体骨移植提供一种可行的替代方法,同时也是自体骨移植物的安全佐剂,具有加速骨折愈合的潜在优势,但目前的证据暂不支持骨形态发生蛋白联合自体骨移植。

Abstract:

BACKGROUND: Bone morphogenetic proteins have strong bone induction properties and have been proved to promote bone healing in fracture, bone defect and other diseases. However, few studies are reported on the use of bone morphogenetic proteins in the treatment of bone nonunion, and the results of various studies remain controversial, which makes the role of bone morphogenetic proteins in the treatment of limb long bone nonunion unclear.

OBJECTIVE: Meta-analysis was used to systematically evaluate the advantages and disadvantages of bone morphogenetic protein versus autogenous bone grafting in the treatment of limb long bone nonunion.

METHODS: PubMed, Elsevier, Web of Science, Cochrane Library, CNKI and WanFang databases were searched to retrieve the randomized controlled trials and non-randomized controlled trials of bone morphogenetic proteins for limb long bone nonunion published before April 2019. Quality evaluation and data extraction of the included literatures were performed. Meta-analysis of outcome indicators was performed using RevMan 5.1 software provided by Cochrane system.

RESULTS AND CONCLUSION: Eight articles were enrolled, including 4 randomized controlled trials and 4 non-randomized controlled trials, all of which were small sample-size studies involving 30-124 cases. A total of 613 cases of nonunion were included. In the study group, patients received bone morphogenetic proteins or bone morphogenetic proteins in combination with bone grafting. In the control group, patients received autologous bone grafting. Meta-analysis results showed that there were no significant differences in postoperative healing rate, infection rate, secondary operation rate, and postoperative improvement in limb function between study and control groups (P > 0.05). The mean healing time in the study group was significantly shorter than that in the control group [WMD=-1.24, 95%CI(-1.70, -0.79), P < 0.01]. Intraoperative blood loss in patients receiving simple bone morphogenetic protein was less than that in patients receiving autologous bone grafting (P < 0.05). The hospitalization cost of bone morphogenetic protein in combination with autologous bone grafting was significantly higher than that of autologous bone grafting (P< 0.01). There was no significant difference in hospital stay between patients receiving simple bone morphogenetic protein and patients receiving autologous bone grafting (P > 0.05). These results suggest that bone morphogenetic protein can provide a viable alternative to autologous bone grafting, and it is also a safe adjuvant for autologous bone grafting, which has the potential advantage of accelerating fracture healing, but the current evidence does not support bone morphogenetic protein in combination with autologous bone grafting.
