Recombinant human bone morphogenetic protein-2 as an adjunct for spine fusion in a pediatric population.
BACKGROUND/AIMS: Recombinant human bone morphogenetic protein-2 (rhBMP-2) is responsible for multiple different signaling processes including positive effects on bone formation and fusion. In 2002, rhBMP-2 was approved for use in anterior lumbar spinal fusion by the Food and Drug Administration. Since that time, rhBMP-2 use for spinal fusion has become widespread. The use of rh-BMP2 for pediatric spinal fusion, however, has not been widely reported. We report the experience of the use of rhBMP-2 for pediatric spinal fusion at the University of Florida. METHODS: Data on patients under the age of 18 years who underwent spinal fusion with rhBMP-2 as an adjunct were retrospectively collected. Of these, 17 met the inclusion criteria and were reviewed. Two patients did not have adequate postoperative imaging. Fifteen patients were included in the final review. RESULTS: All 15 patients showed osseous fusion. Complications included one CSF leak and one wound infection, one misplaced screw requiring revision, and one case of adjacent segment kyphosis requiring extension of the original construct. CONCLUSION: rhBMP-2 is a successful adjunct for fusion in pediatric patients. Many of these patients had congenital defects that historically decrease fusion rates. rhBMP-2 appears safe and has an associated high rate of osseous fusion.
