![]() ![]() How a Spinal Fusion Worksīased on the surgeon’s preference, or if the patient has risk factors for fusion, an electrical bone growth stimulator may be used as an adjunct to spinal fusion surgery to help enhance the chances of achieving a successful bone fusion.īone stimulators can either be implanted under the skin (internal) or worn on the outside of the skin (external). Patients with a diagnosis of Grade III (or worse) spondylolisthesisĪdditional factors that may lessen the chance of obtaining a solid fusion include: osteoporosis, vascular disease, obesity, diabetes, renal disease, alcoholism, and medications that deplete calcium.Patients who are having a multi-level spinal fusion.Patients who have had a previously failed spine fusion.It is generally thought that patients who may be vulnerable to bone healing problems include: While there are no clear-cut rules for when a patient may need electrical stimulation to help achieve a solid fusion. Over time (a few months and up to one year), this bone growth process most often unites the bone graft pieces into a solid union of bone.Įlectrical Bone Growth Stimulation May Help Some Spine Fusion Patients.After the surgery, a process called " osteogenesis" starts, which is the body's way of growing bony tissue.During surgery, the surgeon lays down bone fragments (usually taken from iliac crest in the patient’s hip) in the segment of the spine to be fused.A fusion does not occur immediately at the time of surgery, but rather it is a process that occurs over time. If your EXOGEN device requires a battery service before your fracture is healed, please call the Clinical Therapies Service Center, 1-80. ![]() In the case of a spinal fusion, it is necessary for multiple bone fragments to heal together, or “fuse”, to create one solid bone. The EXOGEN device is powered by a non-replaceable, non- rechargeable lithium battery pack with a life of a minimum of 150 treatments of 20 minutes each. In the same way, application of an electrical stimulator can enhance the body’s natural bone healing process. Broken bone helps promote the body’s bone healing process by creating its own electrical field. Human bone is actually a living tissue and, like skin, has the inherent ability to heal itself when broken or injured. Electrical bone growth stimulators are a supplemental form of therapy to help enhance the body’s bone healing process… a process that is absolutely essential for the success of any type of spinal fusion surgery. ![]()
