Physicians’ Guide: Improve Fusion Outcomes in At-risk Patients
PEMF Bone Growth Stimulation: Non-invasive, adjunct to post-operative care

Why Consider Spine Fusion Stimulation?

Surgeon's choice for patients at-risk of pseudarthrosis

Spinal fusion is a standard of surgical care for many patients with lumbar or cervical disorders.  Degenerative disc disease, spinal stenosis, spondylolisthesis, and trauma typify causes of lumbar and cervical problems.  Indications for fusion include spinal instability, intractable pain, and neurological dysfunction.

While surgeons agree that the goal of spinal fusion is solid arthrodesis, this is difficult to achieve in patients at risk for non-union.  In fact, of the approximately 661,0001 spinal fusions performed  in 2009, the incidence of pseudarthrosis reported in the literature varied widely, ranging from 66%2 to 95%.3  In addition, revision procedures are costly, difficult surgeries with lower success rates compared to primary fusion surgeries.4-5

Improve Spinal Fusion Outcomes

This Physicians’ Guide provides important information to improve fusion outcomes in high-risk patients.  Identifying patients at-risk for pseudarthrosis is the first step followed by applying Orthofix® bone growth stimulation (BGS) as adjunctive therapy for lumbar or cervical fusion, or as a non-surgical alternative for failed lumbar fusion.

There is a substantial amount of literature to show the efficacy of PEMF bone growth stimulation.  The studies show that patients, in particular those with high risk factors….are key candidates.”

“I’ve seen a significant drop in my pseudarthrosis rates — it is probably under 5%…this is despite the facts that the patients in many cases fall into these high risk categories.”

Orthofix Spinal-Stim® and Cervical-Stim® BGS facilitates vascularization, mineralization of osteoid material, and promotes osteoblastic migration essential in bone healing.6 These FDA-approved devices utilize pulsed electromagnetic field (PEMF) technology.  The efficacy of PEMF technology is well-supported in lumbar and cervical studies.

Statement of Indications
Spinal-Stim is a non-invasive electromagnetic bone growth stimulator indicated as an adjunct therapy to increase the probability of fusion success and as a non-operative treatment of salvage of failed spinal fusion, where a minimum of nine months has elapsed since the last surgery.

Cervical-Stim is a non-invasive, pulsed electromagnetic bone growth stimulator indicated as an adjunct therapy to cervical fusion surgery in patients at high-risk for non-union.
