文题释义:
包裹植骨:是指具有机械性包裹作用的包裹材料包裹松质骨植骨方法,如钛网、线网、线捆绑皮质骨块、自体筋膜和人工膜等包裹材料,对植骨材料具有较好稳定作用,避免了植骨材料散开和松动,同时植骨量通常较多,从而避免或明显减少植骨后骨吸收现象。
填塞物“领子”:在诱导膜技术第1阶段手术制作骨水泥填塞物时,在填塞物与骨缺损的断端连接处制作稍大的包裹断端的部分称为填塞物的“领子”。在膨大的“领子”内植骨可以较快形成梭形骨痂连接,可以避免断端连接处发生骨不连。
 
 
背景:诱导膜技术具有良好的骨缺损修复效果,与诱导膜的生物成骨活性和机械性包裹作用有关。由于不同时期植骨诱导膜的生物成骨活性相差较大,尤其是在晚期阶段,诱导膜的生物成骨活性较弱,因此,到底是诱导膜的生物成骨活性或是机械性包裹作用对骨缺损修复的作用更大,仍有不同意见。
目的:将有关诱导膜技术研究现状和应用方法的改良作一综述。
方法:应用计算机检索CNKI数据库、PubMed数据库及Elsevier数据库中收录的相关文献,中文检索词为“骨缺损,诱导膜,诱导膜技术,骨水泥”,英文检索词为“Bone defect,Induced membrane,Induced membrane technique,Bone cement”。查阅1995年1月至2018年12月期间收录的相关文章,包括综述、基础研究及临床研究,通过阅读文题和摘要进行初步筛选,排除与文章主题相关度低的文献,根据纳入标准和排除标准,最终纳入40篇文献进行结果分析。
结果与结论:研究表明,诱导膜技术修复骨缺损既有生物成骨活性因素,又有机械性包裹因素。在感染性骨缺损第1阶段手术可以采用内固定,骨水泥填塞物体外成型可以克服体内成型发热性损伤、难取出等缺陷。植骨时机不同,诱导膜成骨活性不同,因此植骨量应考虑到植骨时机,但最佳的植骨量和植骨材料比例尚缺乏实验研究。可降解填塞物的出现,使一次性诱导膜技术手术变为可能,但大多数可降解填塞物的力学强度较差,膜诱导力较弱。期待新的力学强度更好、膜诱导力更强或可促进骨生长的可降解填塞物出现,有望缩短治疗时间和减少自体骨用量。

Abstract:

BACKGROUND: Induced membrane technique has good effect on repair of bone defect, which is related to the bio-osteogenetic activity and mechanical encapsulation of induced membrane. Due to the large difference in bio-osteogenetic activity at different time of bone grafting, especially in the late phase, the bio-osteogenetic activity of the induced membrane is weak.
OBJECTIVE: To review the research status and modification of application methods of induced membrane technique for repair of bone defect.
METHODS: A computer-based online search of CNKI, PubMed, and Elsevier databases was performed for retrieving articles concerning the research status and modification of application methods of induced membrane technique for repair of bone defect published from January 1995 to December 2018. The search terms were “bone defect, induced membrane, induced membrane technique, bone cement” in Chinese and English, respectively. The types of literature included review, basic and clinical research. The literature was screened preliminarily by reading title and abstract, and the irrelevant articles were excluded. Finally 40 articles eligible for inclusion and exclusion criteria were enrolled for result analysis
RESULTS AND CONCLUSION: The mechanism of induced membrane technique for repair of bone defect includes both biosteogenesis and mechanical encapsulation. Internal fixation can also be used in the first stage of surgery for infected bone defect; bone cement forming in vitro overcomes the shortcomings of fever damage and difficulty in removal. The osteogenetic activity of induced membrane was different at different timing of bone grafting. Therefore, amounts of bone grafting should be required according to different bone grafting times. However, there are few studies on the optimal amount of bone graft and the ratio of bone material. The emergence of degradable spacer makes a single surgery of induced membrane technique possible, but most of the degradable spacers have poor mechanical strength and weak membrane induction ability. It is expected that the emergence of new degradable spacer with better mechanical strength, stronger membrane induction or having the ability to promote bone growth will shorten the treatment time and reduce the amount of bone autograft.
