BackgroundThe oblique lateral interbody fusion (OLIF) procedure is an important component of the surgeon's armamentarium for the treatment of degenerative spinal conditions. OLIF with posterior spinal fixation frequently is performed and requires additional time because the patient is flipped to a prone position and redraped. We report a series of cases in which robotic-assistance was used for a 2-surgeon workflow in which OLIF and single lateral position posterior spinal fixation were performed at the same time, termed simultaneous robotic single position surgery (SR-SPS).MethodsData were collected retrospectively from medical records of 13 consecutive patients who underwent SR-SPS by a single surgeon at an academic center between June and December 2020. Instrumentation accuracy, total operating room time, estimated blood loss, length of stay, and complications were assessed.ResultsA total of 13 patients whose mean age was 64.1 years (range 46-84 years) underwent SR-SPS over a 6-month period. Average follow-up was 10.3 months. All patients were treated for degenerative spine disease. The average operative duration was 111.2 ± 25.2 minutes. A total of 60 pedicle screws were placed bilaterally in the lateral position with an accuracy rate of 95.0%. Complications included 1 postoperative seroma, and 1 patient required reoperation 3 months postoperatively due to a fall.ConclusionsWe report the first case series describing SR-SPS. Our study shows that this method can reduce operative time while ensuring accurate and timely screw placement with minimal complications.Copyright © 2021 Elsevier Inc. All rights reserved.
