ABSTRACT: Objectives: To investigate the effect of lumbar interbody fusion via the oblique
lateral approach (OLIF) in the treatment of single level lumbar
spondylolisthesis. Methods: Retrospective analysis was made on 32 cases
of single level lumbar spondylolisthesis treated by lumbar interbody fusion via
the oblique lateral approach from July 2020 to July 2021. 14 males and 18
females; the age was (66.5 ± 11.5) years (55 - 82
years). 1) The operation time, intraoperative blood
loss and complications were recorded; 2) the scores of visual analog scale. VAS and Oswestry disability index (ODI) of low back pain and
lower limb pain were collected before operation and at the last follow-up; by observing the imaging data, the height of the
intervertebral space, the anterior convex angle of the intervertebral space, the anterior convex angle of the lumbar spine, the sagittal diameter of the dural sac and the spondylolisthesis
were measured. Results: All patients successfully completed the
operation, the average operation time was
(103.9 ± 21.1) min, the average intraoperative bleeding volume was (72.3
± 16.4) ml. There was no vascular injury during the operation, no infection
occurred in all surgical incisions, and Class I/A healing was achieved. The VAS
scores of low back pain and leg pain before operation and at the last follow-up
were lower than those before operation, and the difference was statistically
significant (P the height of intervertebral foramen and the
sagittal diameter of dural sac were greater than those before operation, with
statistically significant differences (P than that before operation, with a
statistically significant difference (P ureteral injury, retrograde ejaculation, intestinal and lumbar plexus
injury. Conclusion: The early clinical effect of OLIF in the
treatment of single level lumbar spondylolisthesis is significant. This
surgical method is minimally invasive, safe and effective, which can
significantly reduce the amount of intraoperative
bleeding and reduce the risk of postoperative complications. Its main
working principle is to make the annulus fibrosus, posterior longitudinal
ligament and ligamentum flavum shrink and recover the height of the intervertebral space through decompression,
loosening and stretching of the intervertebral space, so as to achieve the
reduction of the slipped vertebral body, increase the height of the
intervertebral foramen Enlarge the spinal canal volume and eliminate dynamic
compression to play an indirect decompression role,
improve the symptoms of low back and leg pain, and reconstruct the stability
of the spine through interbody fusion.
