Lumbar fusion: rhBMP-2 reduces rate of fusion failure and reoperation .
Recombinant human bone morphogenetic protein-2 versus autogenous iliac crest bone graft for lumbar fusion: a meta-analysis of ten randomized controlled trials
Arch Orthop Trauma Surg. 2012 Dec;132(12):1725-40. doi: 10.1007/s00402-012-1607-3. Epub 2012 Sep 1This meta-analysis included 10 randomized controlled trials comparing recombinant human bone morphogenetic protein-2 (rhBMP-2) and iliac crest bone graft (ICBG) in patients receiving lumbar fusion. The results from the analysis indicated that the rate of fusion failure was significantly lower in the rhBMP-2 group than in the ICBG group at 6, 12, and 24 months. The rhBMP-2 group was also superior to the ICBG group in terms of the rate of reoperation. The two groups did not differ with respect to Oswestry disability index (ODI) scores.
