In certain cases, lumbar spinal stenosis may lead to lumbar nervous disorder. A previous study indicated that minimally invasive spine surgery (MISS) presents benefits compared with conventional open surgery (COS). In the current study, the efficacy of MISS and COS for lumbar spinal stenosis patients was investigated. A total of 82 patients with lumbar spinal stenosis were enrolled and divided into two age-matched groups that received MISS (n=41) or COS (n=41). Patient parameters, including symptoms, inflammatory score, visual analog score (VAS), wound length, Oswestry Disability Index (ODI), hospital stay and postoperative outcomes were analyzed in the current study. Outcomes indicated that both MISS and COS significantly improved symptoms of lumbar spinal stenosis compared with the baseline. It was observed that MISS resulted in decreased wound length and hospital stay compared with COS for patients with lumbar spinal stenosis. The results revealed that MISS had better outcomes compared with COS in improving ODI and inflammatory score for patients with lumbar spinal stenosis. Notably, it was identified that MISS exhibited improved VAS for back and leg pain compared with the COS group for patients with lumbar spinal stenosis. In conclusion, these outcomes indicate that MISS was more effective compared with COS for improving symptoms in patients with lumbar stenosis.
