Mini-Open Anterior Retroperitoneal Lumbar Interbody Fusion: Oblique Lateral Interbody Fusion for Degenerated Lumbar Spinal Kyphoscoliosis

Abstract Background Oblique lateral interbody fusion (OLIF) has been gained more and more attention in the treatment of degenerative lumbar disease. The goal of this study was to evaluate the effect of indirect decompression in lumbar spinal stenosis with stand-alone OLIF. Methods Sixty-three patients with lumbar spinal stenosis who underwent stand-alone OLIF between July 2017 and May 2018 our department were included. Clinical outcomes including visual analogue scale (VAS) and Oswestry Disability Index (ODI) were recorded. Radiographic outcomes comprising of disc height (DH), foraminal height (FH) and lumbar lordosis (LL) were measured. Intraoperative data and complications were collected. All the data were compared preoperatively and postoperatively. Results Eighty-two segments were fused in sixty-three patients using stand-alone OLIF. The average follow-up time was 21.9±3.5 months (range from 16 to 28 months). The DH increased from 0.9±0.3 cm preoperatively to 1.3±0.2 cm postoperatively, and the final follow-up was 1.1±0.2 cm (P < 0.01). The FH increased from 1.7±0.3 cm before surgery to 2.3±0.3 cm after surgery, but decreased to 2.1±0.3 cm at final follow-up (P < 0.01). The LL increased from 38.0°±15.6° before surgery to 42.7°±13.0° at the final follow-up (p<0.01). The VAS and ODI scores of all patients significantly improved at the final follow-up (p<0.01). The total complication rate was 30.2%. Only three patients received revision of posterior decompression and pedicle screw fixation. Conclusions Stand-alone OLIF is an effective option in selected patients with lumbar spinal stenosis.

Abstract INTRODUCTION The oblique lateral interbody fusion OLIF is an alternative anterior approach to the lumbar spine at L5-S1, and it is unknown how it compares to anterior lumbar interbody fusion ALIF. This abstract is to compare the radiographic and clinical factors of ALIF and OLIF at L5-S1 only. METHODS A retrospective review of patients who underwent ALIF or OLIF at L5-S1 only at the University of California San Francisco (2013-2018) was performed. Data collected were demographics, cage parameters, perioperative factors, and radiographic parameters. RESULTS A total of 58 patients were included (33 ALIF and 25 OLIF). The average surgical time was 211.94 min for ALIF and 154.86 min for OLIF (P < .001). The average blood loss was 214 ml for ALIF and 74 ml for OLIF (P < .001). The average day to solid food was 2.55 for ALIF and 0.8 for OLIF (P < .001). The average cage height was 14.78 mm for ALIF and 12.9 mm (P < .001) for OLIF. The average cage lordosis was 15.45° for ALIF and 12.68° (P = .76) for OLIF. Average anterior L5-S1 disc height increase was 8.52 mm (ALIF) and 5.02 mm (OLIF) (P = .018), and average posterior L5-S1 disc height increase was 3.34 mm (ALIF) and 1.30 mm (OLIF) (P = .034). The average L5-S1 segmental lordosis increase was 6.82° for ALIF and 7.63° for OLIF (P = .638). CONCLUSION Patients who underwent OLIF at L5-S1 had shorter ileus duration compared to ALIF and comparable operative times and blood loss. ALIF afforded larger cages to be placed, resulting in greater disc height, but there was no significant difference in L5-S1 segmental lordosis.
