DJO® Announces Presentation of Independent Clinical Study Using CMF™ Device

March 18, 2019

VISTA, Calif.–(BUSINESS WIRE)–DJO®, a leading global provider of medical technologies designed to get and keep people moving, announced today Oregon Health & Science University’s independent study of patients who have undergone lumbar fusions with use of non-invasive electrical stimulation. The results, presented at Spine Summit 2019 in Miami, Florida, highlight the fusion and re-operation rates of 46 study participants.

This study was led by Khoi Than, M.D., of Oregon Health & Science University (Portland, Oregon) and presented at Spine Summit, Miami, 2019 by medical student, Barry Cheaney II.

Highlights from the OHSU study include:

All patients included:

  • 46 total patients studied; 27 CMF™, 19 PEMF
  • Among CMF™ patients, 77.8% (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 healing1,2. The pivotal study: a prospective, randomized, double blind trial, showed statistically significant healing with use of CMF™ over placebo (21 percentage pts). Results of the study showed that CMF™ can provide a 49% increase in overall healing rate3.

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.
