Clinical Results of Oblique Lateral Interbody Fusion (OLIF) Technique Compared with Conventional Lumbar Posterior Laminar Decompression for Lumbar Spinal Stenosis |Biomedgrid

Objective:To compare and analyze the safety and effectiveness of oblique lateral interbody fusion (OLIF) technique and conventional lumbar posterior laminar decompression for lumbar spinal stenosis (DLCS). Methods:From October 2019 to November 2021 68 patients with lumbar spinal stenosis over 60 years of age were divided into OLIF group and traditional decompression group according to their treatment methods. There were 32 patients (14 males and 18 females) in the OLIF group, with an age distribution of 60 years or older and a mean of (69.56 ± 4.18) years, and 36 patients (15 males and 21 females) in the traditional decompression group, with an age distribution of 60 years or older and a mean of (70.32 ± 4.82) years, treated with traditional posterior decompression internal fixation of the vertebral plate. The general data, operation time, intraoperative bleeding, hospital stay, surgical complications, clinical efficacy evaluated by modified Macnab criteria, and patients' preoperative and final postoperative pain visual analog scale scores (VAS) and Owelty dysfunction index (ODI) were statistically analyzed in both groups.
