Efficacy of Single-Position Oblique Lateral Interbody Fusion Combined With Percutaneous Pedicle Screw Fixation in Treating Degenerative Lumbar Spondylolisthesis: A Cohort Study

Abstract

ObjectiveTo investigate the surgical outcomes of single-position oblique lateral interbody fusion (OLIF) combined with percutaneous pedicle screw fixation (PPSF) in treating degenerative lumbar spondylolisthesis (DLS).MethodsWe retrospectively analyzed 85 patients with DLS who met the inclusion criteria from April 2018 to December 2020. According to the need to change their position during the operation, the patients were divided into a single-position OLIF group (27 patients) and a conventional OLIF group (58 patients). The operation time, intraoperative blood loss, hospitalization days, instrumentation accuracy and complication rates were compared between the two groups. The visual analog scale (VAS) and Oswestry Disability Index (ODI) were used to evaluate the clinical efficacy. The surgical segment's intervertebral space height (IDH) and lumbar lordosis (LL) angle were used to evaluate the imaging effect.ResultsThe hospital stay, pedicle screws placement accuracy, and complication incidence were similar between the two groups (P > 0.05). The operation time and intraoperative blood loss in the single-position OLIF group were less than those in the conventional OLIF group (P < 0.05). The postoperative VAS, ODI, IDH and LL values were significantly improved (P < 0.05), but there was no significant difference between the two groups (P > 0.05).ConclusionsCompared with conventional OLIF, single-position OLIF combined with PPSF is also safe and effective, and it has the advantages of a shorter operation time and less intraoperative blood loss.

Different Moro Zones of Psoas Major Affect the Clinical Outcomes after Oblique Lumbar Interbody Fusion: A Retrospective Study of 94 Patients

“…OLIF has been widely used in spine surgery because it allows back muscles and tissues to be well protected. Consistent with previous findings, our study reconfirmed that OLIF is safe and effective in the treatment of degenerative lumbar diseases [14][15][16][17][18][19]. Intervertebral space, foramen, and ligamentum flavum were distracted intraoperatively, therefore relieving neurological symptoms caused by intervertebral space collapse or foraminal stenosis and dorsal compression of the thecal sac.…”

Simultaneous Single-Position Oblique Lateral Interbody Fusion Combined With Unilateral Percutaneous Pedicle Screw Fixation for Single-Level Lumbar Tuberculosis: A 3-Year Retrospective Comparative Study

“…The combination provided adequate mechanical rigidity close to traditional dual pedicle fixation without the need of dealing with contralateral pedicle, given the trouble of contralateral pedicle fixation in lateral position. It should be noted that dual pedicle screw placement in single lateral position was also feasible, only if patients should be placed close to the edge of operation table and elevated higher than the normal [ 32 ], which might result in unnecessary inconvenience and security concern. Lastly, it had to be admitted that a learning curve existed before surgeons got accustomed to unilateral posterior instrumentation in lateral position.…”

The Evolution of Lateral Lumbar Interbody Fusion: A Journey from Past to Present

“…However, with the advent of single-position surgery (SPS), both XLIF and OLIF can be performed in a single position, predominantly the former, along with posterior stabilization (PS). This eliminates the need for patient repositioning, ultimately enhancing surgical efficiency and minimizing complications [ 135 , 140 , 141 , 142 ]. There are currently two main approaches to SPS: Lateral-SPS (L-SPS) and Prone–SPS (P-SPS), where the patient is placed either in the lateral decubitus or prone position, respectively, throughout the entire surgical duration.…”
