Data obtained from a retrospective study involving the Spinal Elements’ Magnum+ device used in anterior lumbar interbody fusion have demonstrated a 96% rate of solid arthrodesis at an average of 7.3±2.3 months post-implantation.

The Magnum+ devices in the study were PEEK implants with the company’s proprietary Ti-bond porous titanium coating. Results of the study were published in the International Journal of Spine Surgery.

Previously-published studies of standard PEEK interbody spacers have shown solid fusion rates of around 90% at 18 months.

As well as high fusion rates, there was significant improvement in nine-month postoperative visual analogue score low back pain (4.5±2.4 point improvement) and visual analogue score leg pain (4.1±3.3 point improvement). Additionally, there were no observations of implant subsidence.

Furthermore, there was no significant difference in visual analogue score low back or leg pain improvement between groups when the data was stratified by gender, age, tobacco use, comorbidities, prior surgery, fusion construct length, use of supplemental posterior instrumentation, body mass index, or diagnosis.

“I have been very pleased with my results using the Magnum+ device with Ti-bond coating,” says Ramin Raiszadeh of the Spine Institute of San Diego, San Diego, USA. “This data quantifies the successes I have been experiencing clinically.”
