Abstract: BACKGROUND: The technique of oblique lumbar interbody fusion has become increasingly mature, but when pedicle screw internal fixation is performed through posterior approach, the fluoroscopy-assisted pedicle screw insertion using a traditional open technique still brings greater trauma to the patient. With the advancement of technology, robot-assisted surgery systems have provided clinicians with new options. OBJECTIVE: To explore the clinical outcomes of percutaneous robot-assisted minimally invasive pedicle screw insertion in an oblique lumbar interbody fusion procedure. METHODS: Totally 78 patients with lumbar degenerative disease who attended Department of Spinal Surgery, Beijing Jishuitan Hospital were treated with oblique lumbar interbody fusion. When lumbar pedicle screw internal fixation was performed through posterior approach, 36 cases (trial group) underwent percutaneous robot-assisted minimally invasive pedicle screw insertion, and 42 cases (control group) underwent fluoroscopy-assisted open invasive screw insertion. The difference in operation time, visual analogue scale score, Oswestry disability index, intraoperative and postoperative blood loss was compared between the two groups. RESULTS AND CONCLUSION: The operative time of trial group was shorter than that of control group (P < 0.05). The postoperative visual analogue scale score of the trial group was lower than that of the control group (P < 0.05). The amount of intraoperative and postoperative blood loss in the trial group was less than that in the control group (P < 0.05). It is concluded that robot-assisted pedicle screw insertion in oblique lumbar interbody fusion can shorten the operative time, reduce intraoperative blood loss, lessen risk of surgical complications, and reduce the soft tissue damage of lumbar spine.
