Burton, who said the study "highlights the trend that many of us would have guessed, that the use of BMP is skyrocketing," added that more recent data might show something different.
If the study looked at data from 2007, he said, he believes the rates of anterior cervical complications would be reduced because many surgeons aren't using BMP for fusions in that area or are using smaller doses of the biological agent.
The surgeons agreed that more research is needed to determine who is an ideal candidate for BMP use and to assess the costs and benefits of the therapy.
The U.S. National Library of Medicine has more on spinal fusion surgery.
