NuVasive has announced that a new study published in The Spine Journal could validate single-position spine surgery as having significant advantages over traditional, open spinal fusion.
The study entitled “Single position circumferential fusion improves operative efficiency, reduces complications and length of stay compared with traditional circumferential fusion,” is a multi-centre, retrospective study and 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.
According to NuVasive, 237 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 Aaron Buckland, spine and scoliosis surgeon at Melbourne Orthopaedic Group (Melbourne, Australia). “The results of this study further validate that this practice-changing technique leads to clear benefits for the patient, surgeon and provider.”
According to the press release, 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% fusion rates and up to 90% reduction in blood loss; reduced operative time by up to 60 minutes, resulting in less time under anesthesia and 50% shorter length of stay in the hospital; and enhanced economics with up to a 20% increase in case volumes and as much as US$5,000 saved per patient in hospital costs.
