NuVasive announced the results of the study, "Single position circumferential fusion improves operative efficiency, reduces complications and length of stay compared with traditional circumferential fusion," 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. Of those, 237 underwent single-position lateral surgery (SPLS) and 153 underwent a "flip" surgery.
Results indicate that SPLS reduced operating time by more than three hours, and led to a reduction in blood loss and intraoperative radiation dosage. Further, patients who underwent SPLS experienced lower postoperative intestinal blockage, and length of stay in the hospital was reduced on average by two days.
Of note, the approach yielded enhanced economics with up to a 20% increase in case volumes and as much as $5,000 saved per patient in hospital costs.
NuVasive launched the X360 system in mid-2019, integrated with Pulse™ automation platform for lateral single-position surgery.
"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."
