This study was led by Khoi Than, M.D., of Oregon Health & Science University (Portland, Ore.). Highlights from the OHSU study include:
- Forty-six total patients studied; 27 CMF, 19 PEMF
- Among CMF patients, 77.8 percent (21) demonstrated solid fusion
- None of the patients treated with the CMF device required re-operation for pseudarthrosis
“There are a number of factors impacting a patient’s recovery from spinal fusion,” said Khoi Than, M.D., of Oregon Health & Science University. “We suspected post-op therapy could have meaningful impact, so we decided to look at two of the industry’s leading bone growth stimulators head-to-head. There’s more work to be done, but our initial data is very interesting.”
The FDA has approved the use of multiple non-invasive electrical stimulation therapies to support post-operative bone growth since 1990. The therapies utilize different underlying technologies and vary significantly in treatment regimen, ease-of-use and effectiveness.
Combined Magnetic Field Technology from DJO is a once daily, 30-minute non-invasive electromagnetic stimulation indicated as an adjunct to lumbar spine fusion. Once-daily treatment of CMF Technology stimulates the factors in the bone healing cascade that help improve bone healing.1,2 The pivotal study, a prospective, randomized, double blind trial, showed statistically significant healing with use of CMF over placebo (21 percentage points). Results of the study showed that CMF can provide a 49 percent increase in overall healing rate.3
CMF SpinaLogic is a lightweight device that can be applied over a brace or clothing after lumbar spine fusion surgery and offers one button start/stop as well as built in compliance tracking. Patients receive personalized service from highly trained account representatives available to size, fit and train.
DJO develops and distributes medical devices that provide solutions for musculoskeletal health, joint reconstruction, vascular health, and pain management. The company’s range of products and integrated technologies address the orthopedic continuum of care from performance and mobility to surgical intervention and post-operative rehabilitation; enabling people around the world to regain or maintain their natural motion.
