Single position L5-S1 lateral ALIF with simultaneous robotic posterior fixation is safe and improves regional alignment and lordosis distribution index – Lumbar Fusion

Day Case Lumbar Fusion Surgery

This article discusses the technique of minimally invasive single position lateral anterior lumbar interbody fusion (ALIF) at L5-S1 with simultaneous robot-assisted posterior fixation. The study conducted a retrospective case series of 17 patients and evaluated radiographic parameters, lordosis distribution index (LDI), complications, pedicle screw accuracy, and inpatient metrics. The results showed significant improvements in lordosis and global alignment without any major complications. The authors concluded that this technique is safe and effective for improving alignment and the distribution of lordosis in patients undergoing ALIF at L5-S1. The article provides valuable insights into the technical and anatomical considerations of this procedure

ABSTRACT

PURPOSE: Minimally invasive single position lateral ALIF at L5-S1 with simultaneous robot-assisted posterior fixation has technical and anatomic considerations that need further description.

METHODS: This is a retrospective case series of single position lateral ALIF at L5-S1 with robotic assisted fixation. End points included radiographic parameters, lordosis distribution index (LDI), complications, pedicle screw accuracy, and inpatient metrics.

RESULTS: There were 17 patients with mean age of 60.5 years. Eight patients underwent interbody fusion at L5-S1, five patients at L4-S1, two patients at L3-S1, and one patient at L2-S1 in single lateral position. Operative times for 1-level and 2-level cases were 193 min and 278 min, respectively. Mean EBL was 71 cc. Mean improvements in L5-S1 segmental lordosis were 11.7 ± 4.0°, L1-S1 lordosis of 4.8 ± 6.4°, sagittal vertical axis of – 0.1 ± 1.7 cm°, pelvic tilt of – 3.1 ± 5.9°, and pelvic incidence lumbar-lordosis mismatch of – 4.6 ± 6.4°. Six patients corrected into a normal LDI (50-80%) and no patients became imbalanced over a mean follow-up period of 14.4 months. Of 100 screws placed in lateral position with robotic assistance, there were three total breaches (two lateral grade 3, one medial grade 2) for a screw accuracy of 97.0%. There were no neurologic, vascular, bowel, or ureteral injuries, and no implant failure or reoperation.

CONCLUSION: Single position lateral ALIF at L5-S1 with simultaneous robotic placement of pedicle screws by a second surgeon is a safe and effective technique that improves global alignment and lordosis distribution index.
