A bone stimulation device is an electronic device which stimulates bone growth by sending low-level pulses of electromagnetic energy to an injury site, according to the Indian Journal of Orthopaedics. Bone stimulation is commonly prescribed for patients whose bones do not heal properly after injury or spinal fusion surgery.
Bone stimulation devices may be worn externally or implanted at the bone healing site, the Indian Journal of Orthopaedics. Orthofix is a medical company that produces external bone growth stimulators. According to studies by multiple medical doctors referenced on the Orthofix website, low-level electromagnetic fields positively affect bone healing on molecular, cellular and tissue levels. The device activates growth pathways between molecules, which increases the number and maturity of bone cells. This increases bone strength and quality on the tissue level, which promotes healing and pain reduction.
According to studies conducted by Abraham Rogozinski, M.D., and Chaim Rogozinski, M.D., the use of bone growth stimulators can improve healing in patients recovering from spinal fusion surgery, even in high risk patients such as smokers and those undergoing multiple back surgeries. The Indian Journal of Orthopaedics noted that implanted bone growth stimulators may lead to greater complications than external devices. These complications include infection and pain at the implantation site.
