Some patients who experience nonunion fractures and spinal fusion surgery have difficulty healing. In many of these cases, there are certain health factors that may have impaired the natural healing process of the bones. To help overcome healing challenges, doctors commonly prescribe a treatment called bone growth therapy, otherwise known as bone growth stimulation. CMF Bone Growth Therapy devices provide a safe, noninvasive treatment that helps promote healing in fractured bones and spinal fusions that have not healed or have difficulty healing.
