This observational study evaluates the clinical outcomes and procedural characteristics of navigation-assisted oblique lumbar interbody fusion (OLIF) in patients with lumbar degenerative disease. Between July 2021 and December 2021, adult patients undergoing OLIF with robotic or navigation assistance at Cheng Hsin General Hospital were included. Navigation systems were used to guide interbody cage placement and percutaneous pedicle screw insertion.
Information regarding operative time, intraoperative blood loss, radiation exposure to patients and operating room staff, and postoperative complications was collected. Clinical outcomes, including back and leg pain and lumbar function, were assessed during routine postoperative follow-up.
This study aims to describe the feasibility and short-term outcomes of navigation-assisted OLIF, including screw placement accuracy and early postoperative clinical improvement, and to provide additional clinical information regarding the use of navigation systems in minimally invasive lumbar fusion surgery.
