Introduction

Traditional OLIF combined with posterior pedicle screw placement requires patients to perform the procedure in two different positions, which greatly increases the operation time and the risk of radiation exposure.  In addition, due to the limitations of X-ray fluoroscopy, screw misplacement rate is also higher.

 Methods

From August 2020 to October 2021, a total of 3 patients with degenerative lumbar disease were enrolled in our study. All patients underwent single-position computer navigation assisted oblique lumbar interbody fusion and percutaneous pedicle screw fixation. The total operation time, blood loss, pedicle screw placement time were recorded. Radiological examinations and Visual analogue scale (VAS), Oswestry disability index (ODI) were used to evaluate the radiological and clinical efficacy.

 Results

A total of 3 patients were included in this study. The average followed-up was (9.6±1.2) months. All surgeries were successfully completed. The average total operation time was (116.2±20.5) min, the average blood loss was (84.2±20.3) ml. Average total pedicle screw placement time was (43.0±2.6) min. The VAS and ODI decreased significantly at each follow-up. Imaging showed no loosening or rupture of internal fixation at each follow-up. The intervertebral fusion rate was 100% by the latest follow-up, and the accuracy of pedicle screw placement was 100% .

 Discussion

Synergy OLIF 360 for treatment of degenerative lumbar disease is feasible, safe and effective, which can optimize suigical procedures, avoid reposition and save operation time.
