A bone growth agent used in thousands of spinal fusion surgeries for neck pain has been linked to complications and higher cost, according to the first nationwide study of the product. Spinal fusion is one option for people with back and neck pain, although some researchers have questioned how well it works.
In a spinal fusion, a surgeon removes the disc between two vertebrae and replaces it with the patient’s own bone, BMP or another product. If successful, new bone grows and fuses the vertebrae into one piece, stabilizing the spine.
Safety questions arose last year about the protein product, BMP, when used in fusion surgeries in the neck region, a use not approved by federal regulators. Doctors are allowed to use products such as this for purposes for which they have not been approved. The lead author of the study which appears in the latest issue of the Journal of the American Medical Association reported that some of these complications are life-threatening because the neck is such a sensitive area.
