Exogen bone stimulator12/23/2023 ![]() Due to the slow uptake of bone growth stimulators, surgical intervention represents standard of care (and the relevant comparator) within the health system. These include i) issues caused by the requisite use of a gel medium for device signals to transmit, and ii) long durations of wear time (20 minutes to beyond 2 hours). Broad uptake in bone growth stimulators has been slow due to compliance factors. For example, the CMF OrthoLogic 1000 (OL1000) device is a portable, battery-powered medical device that provides local magnetic field treatment through very low-energy combined static and dynamic magnetic fields. ![]() While EXOGEN uses LIPUS to facilitate fracture healing, other bone growth stimulators use electrical currents or magnetic stimulation to achieve this outcome. EXOGEN, a device that uses low-intensity pulsed ultrasound (LIPUS) at the fracture nonunion site, has demonstrated cost-savings when compared with invasive nonunion surgery for tibial fractures. To reduce the need for surgical intervention, noninvasive bone healing devices known as bone growth stimulators may be used to treat fracture nonunions. ![]() In addition, there is a high cost to the health care system due to the need for surgical intervention and extended patient care and follow-up. Additional surgeries are burdensome for fracture patients as they often lead to prolonged disability and an increased loss of function and productivity. Types of procedures used to promote fracture healing include internal fixation or external fixation and bone grafting. Fracture nonunions often require surgical intervention to promote fracture healing. Tibia fractures are at higher risk of nonunion given the lack of soft tissue envelope and resulting limitation of blood supply.įracture nonunions are associated with substantial pain, reduced mobility, prolonged morbidity, and a lower quality of life. A population-based study estimated the incidence of nonunion to be 13 per 1,000 per annum for pelvis and femur fractures, per annum for the humerus fractures, and per annum for the tibia and fibula fractures. Rates of nonunion vary by the bone fractured. The National Institute of Health and Care Excellence (NICE) defines fracture nonunion as fractures that have not reached bony union within 6 to 9 months after the initial fracture treatment. Fracture nonunions, although representative of a smaller proportion of fracture care outcomes, have devastating impacts on morbidity and health care costs.
