Not exactly. Your doctor may be referring to the proteins that exist naturally in the body. These proteins make new cells and help existing cells to do their jobs.

Researchers have recently discovered that using these proteins in spine surgery may stimulate bone growth, giving spinal fusion a boost. Researchers are especially excited about bone morphogenic proteins (BMPs). BMPs may speed the healing of bone grafts from the patient's own body or from transplants.

So far, BMPs and other proteins have mainly been tested on animals. And they haven't gained FDA approval. There is much research to be done. Still, this looks to be a promising new development for patients in need of added help with spinal fusion.
