Bone morphogenetic protein 2 is shown to stimulate the production of bone.Recombinant human protein (rhBMP-2) is currently available for orthopaedic usage in the United States. Implantation of BMP-2 in a collagen sponge induces new bone formation and can be used for the treatment of bony defects, delayed union, and non-union.
Bone morphogenetic protein 2 has also found its way into the field of Dentistry. The use of dual tapered threaded fusion cages and recombinant human bone morphogenetic protein-2 on an absorbable collagen sponge obtained and maintained intervertebral spinal fusion, improved clinical outcomes, and reduced pain after anterior lumbar interbody arthrodesis in patients with degenerative lumbar disc disease. As an adjuvant to allograft bone or as a replacement for harvested autograft, bone morphogenetic proteins (BMPs) appear to improve fusion rates after spinal arthrodesis in both animal models and humans, while reducing the donor-site morbidity previously associated with such procedures.
A study published in 2011 noted "reports of frequent and occasionally catastrophic complications associated with use of [BMP-2] in spinal fusion surgeries", with a level of risk far in excess of estimates reported in earlier studies.
