Comparison of the effects between oblique lateral interbody fusion (OLIF) and minimally invasive transforaminal interbody fusion (MIS-TLIF) in the treatment of adult degenerative lumbar scoliosis.

Background: Managing adult degenerative lumbar scoliosis (ADLS) presents a complex challenge, requiring advanced, minimally invasive surgical techniques.
Objective: This study aims to evaluate and compare the efficacy and outcomes of oblique lateral interbody fusion (OLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) in treating ADLS, with an emphasis on surgical methods, recovery times, and spinal correction results.
Methods: We reviewed 42 patients with ADLS who did not respond to conservative treatments. These patients underwent either OLIF or MIS-TLIF procedures. Key factors analyzed included surgical duration, blood loss, complications, and changes in preoperative and postoperative lumbar lordosis (LL), anterior and posterior disc height (ADH, PDH), and Cobb angles. Statistical analysis was conducted using SPSS software, with significance determined at p < 0.05.
Results: The OLIF technique showed notable benefits in multi-segment spinal corrections, particularly in enhancing intervertebral disc height and correcting Cobb angles. While both surgical methods effectively addressed spinal deformities, OLIF was less invasive, resulting in reduced blood loss, shorter surgery times, and fewer complications. No significant differences were found between the two techniques for single-segment corrections.
Conclusion: For multi-segment spinal corrections in ADLS, OLIF is a superior choice due to its minimal invasiveness and favorable recovery profile. However, for patients with primarily radicular symptoms and no significant postural alterations, MIS-TLIF may be more appropriate.
