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.
