Review Meta Analysis
Bone morphogenetic proteins in anterior cervical fusion: a systematic review and meta-analysis.
Bone morphogenetic proteins (BMPs) have been commonly used as a graft substitute in spinal fusion. Although the U.S. Food and Drug Administration issued a warning on life-threatening complications of recombinant human BMPs (rhBMPs) in cervical spine fusion in 2008, their off-label use has been continued. This investigation aimed to review the evidence for the use of rhBMP-2 and rhBMP-7 in anterior cervical spine fusions. ⋯ Application of rhBMPs in cervical spine fusion yields a significantly higher fusion rate with similar patient-reported outcomes, yet increased risk of life-threatening complications. Thus, we do not recommend the use of rhBMP in anterior cervical fusions.
