Abstract:

Objective

To study the efficacy of decalcified bone matrix (DBM) in limb bone grafting surgery. A systematic review and meta-analysis of all available data was conducted to evaluate the effectiveness and safety of DBM as a bone graft substitute in limb limb grafting.

Methods

Literature research was performed in the PubMed, MEDLINE, EMBASE and the Cochrane Library. The application of DBM in bone grafting of limbs was retrieved and selected according to the literature inclusion criteria. Focus on selecting articles that can be extracted and meta-analyzed.

Results

Forty-four studies met the inclusion criteria, including three randomized controlled trials, 27 case series studies, and 14 case-control studies. None of the studies reported the destruction or displacement of DBM as a fusion site of the graft.

Conclusions

A series of case studies suggest that the use of Allomatrix DBM as a surrogate for autologous bone grafts has an unacceptably high risk of complications. The results of the remaining 43 studies reported that DBM was non-inferior compared to autologous bone and other bone graft substitute materials. According to the follow-up report of patients, the fusion rate and safety of DBM as a substitute material for bone graft can be considered. It is guaranteed, but the amount and quality of evidence in this area is very limited.
