NuVasive’s X360 Procedural Approach Validated in Clinical Study Published in The Spine Journal Finding Single-Position Spine Surgery Improves Operative Efficiency While Reducing Complications and Length of Hospital Stay

SAN DIEGO – January 6, 2021 – NuVasive, Inc. (NASDAQ: NUVA), the leader in spine technology innovation, focused on transforming spine surgery with minimally disruptive, procedurally integrated solutions, today announced the results of the study, “Single position circumferential fusion improves operative efficiency, reduces complications and length of stay compared with traditional circumferential fusion,” in The Spine Journal, validating single-position spine surgery as having significant advantages over traditional, open spinal fusion.

The multi-center, retrospective study included 390 patients who underwent anterior lumbar interbody fusion (ALIF) and/or lateral lumbar interbody fusion (LLIF) surgery with bilateral percutaneous pedicle screw fixation between L2-S1. Two hundred and thirty-seven patients underwent single-position lateral surgery (SPLS) and 153 underwent a “flip” surgery. The study found that SPLS reduced operating time by more than three hours, and led to a reduction in blood loss and intraoperative radiation dosage for the patient. Further, patients who underwent SPLS experienced lower postoperative intestinal blockage (ileus), and their length of stay in the hospital was reduced on average by two days.

“As an early adopter of the NuVasive X360 system, the clinical benefits and operative efficiency of single-position surgery over traditional surgery, that requires patient repositioning, continue to be proven throughout my practice,” said Dr. Aaron Buckland, spine and scoliosis surgeon at Melbourne Orthopaedic Group in Melbourne, Australia. “The results of this study further validate that this practice-changing technique leads to clear benefits for the patient, surgeon and provider.”

The results of this study build upon other clinical evidence validating X360®, NuVasive’s comprehensive approach to lateral single-position surgery that combines XLIF®, XALIF™ and XFixation™ and is clinically proven to provide better outcomes over traditional open spinal fusion, including:

  • Improved clinical outcomes with >95 percent fusion1 rates and up to 90 percent reduction in blood loss;1
  • Reduced operative time by up to 60 minutes,2 resulting in less time under anesthesia and 50 percent shorter length of stay in the hospital;3 and
  • Enhanced economics with up to a 20 percent increase in case volumes4 and as much as $5,000 saved per patient in hospital costs.5,6

“Clinical results of the X360 surgical system reiterate NuVasive’s proceduralization strategy that enables surgeons to be more efficient in the operating room and deliver better clinical outcomes for their patients,” said Massimo Calafiore, executive vice president, Global Business Units at NuVasive. “Further, it affirms the Company’s continued focus on using data and research to inform its surgeon training and education on the X360 system that will serve as a key growth driver for the company in 2021 and beyond.”
