Orthofix Announces Publication of New Data Supporting Use of PEMF Stimulation in Lumbar Spine Fusion Procedures for Patients at Risk of Pseudarthrosis

December 21, 2023

Orthofix Medical Inc. (NASDAQ:OFIX), a leading global spine and orthopedics company, today announced the publication of new data from a prospective, multicenter study investigating Pulsed Electromagnetic Field (PEMF) stimulation as an adjunct therapy to lumbar spinal fusion procedures in patients at risk for pseudarthrosis. Published in the International Journal of Spine Surgery1, patients treated with the SpinalStimbone growth therapy device demonstrated a high rate of successful fusion with significant improvements in pain, function and quality of life, despite having risk factors for pseudarthrosis.

“Patients with risk factors such as a prior failed fusion, the need for a multilevel fusion, nicotine use, osteoporosis or diabetes often have a difficult time healing after lumbar fusion surgery,” said lead author Dr. Marc Weinstein, an orthopedic spine surgeon at the Florida Orthopaedic Institute in Tampa, Florida. “These risk factors contribute to complications and pseudarthrosis, which can prolong pain and ultimately reduce quality of life. This data reinforces the use of PEMF stimulation after lumbar fusion surgery to improve outcomes regardless of the patients’ risk factors.”

The prospective study conducted at 10 centers across the U.S. analyzed a total of 142 patients with one or more risk factors for pseudarthrosis. Participants were assigned in-home use of the SpinalStim bone growth therapy device for six months following surgery. Fusion was determined by radiographic imaging at 12 months. Successful fusion for patients with one, two or three or more risk factors was 88.5 percent, 87.5 percent and 82.3 percent respectively. Patient reported outcomes that measure disability, function, pain, quality of life, and overall well-being were also evaluated with significant improvements noted when compared to baseline.

“The SpinalStim bone growth therapy device provides a noninvasive and cost-effective means to augment spinal fusion procedures that enables the patient to continue their healing at home,” said Kevin Kenny, President, Orthofix Global Spine. “This new data is important as it adds to the body of evidence supporting the use of PEMF for high-risk patients who face challenges with bone fusion healing.”

About the SpinalStim Bone Growth Therapy Device

The SpinalStim device is the only bone growth stimulation therapy system that is FDA-approved as both an adjunct treatment for lumbar spinal fusion and as a nonsurgical treatment for spinal pseudarthrosis. The device utilizes PEMF technology that provides 360 degrees of treatment coverage around the fusion site2 and has an overall success rate of 92 percent3 in treating spinal fusion surgery patients. Use of the SpinalStim device is supported by the North American Spine Society’s coverage recommendation4.
