Adjunctive Use of Bone Growth Stimulation Increases Cervical Spine Fusion Rates in Patients at Risk for...

Area of Science:

• Orthopedics and Spine Surgery
• Biomedical Engineering
• Clinical Trials

Background:

• Pseudarthrosis, a complication of spinal fusion, leads to persistent pain and functional decline.
• Identifying patients at risk for pseudarthrosis is crucial for optimizing surgical outcomes.
• Current treatments for high-risk patients often have limited efficacy.

Purpose of the Study:

• To assess the efficacy of pulsed electromagnetic field (PEMF) therapy in enhancing cervical spine fusion rates.
• To evaluate PEMF treatment in patients with pre-existing risk factors for pseudarthrosis.
• To compare fusion outcomes between PEMF-treated and control groups.

Main Methods:

• A prospective multicenter clinical trial with a retrospective control arm (NCT03177473).
• PEMF treatment administered for 6 months post-surgery.
• Fusion status assessed at 12 months via radiography and CT scans.

Main Results:

• The PEMF group (n=160) exhibited significantly higher fusion rates (90.0%) compared to the control group (n=53; 60.4%).
• PEMF demonstrated superior outcomes in patients with multi-level disease and high BMI.
• The PEMF group had a higher prevalence of baseline risk factors, including nicotine use, osteoporosis, and advanced age.

Conclusions:

• Adjunctive PEMF stimulation significantly improves cervical spine fusion rates in at-risk patients.
• PEMF therapy offers a viable solution for enhancing fusion success in complex spinal fusion cases.
• PEMF treatment is safe and effective for improving outcomes in patients predisposed to pseudarthrosis.
