Patients with lumbar degenerative disease who underwent L4\u2010L5 oblique lumbar interbody fusion (OLIF) or posterior decompression using CBT screws between February 2016 and February 2019 were included. Patients in whom PS was used were matched for age, sex, height, weight, and BMI. Record the operation time, blood loss. All enrolled patients underwent lumbar CT imaging at one\u2010year follow\u2010up to evaluate the fusion rate. At the two\u2010year follow\u2010up the visual analogue scale (VAS), Oswestry disability index (ODI), and Japanese Orthopaedic Association scores (JOA) were used to identify symptom improvement. Independent <jats:italic>t<\/jats:italic>\u2010test was used for the comparison, and score data were analyzed using the <jats:italic>\u03c7<\/jats:italic><jats:sup>2<\/jats:sup> and exact probability tests.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>A total of 144 patients with were included.

Twenty\u2010eight patients underwent OLIF and CBT screw fixation, 36 underwent OLIF and PS fixation, 32 underwent posterior decompression and CBT screw fixation, and 48 underwent posterior decompression and PS fixation. The fusion rates following CBT screw and PS fixations in OLIF were 92.86% (26\/28) and 91.67% (33\/36), respectively (<jats:italic>P<\/jats:italic>\u00a0=\u00a01). The fusion rates following CBT screw and PS fixations in posterior decompression were 93.75% (30\/32) and 93.75% (45\/48), respectively (<jats:italic>P<\/jats:italic>\u2009&gt;\u20090.05). Regardless of OLIF or posterior decompression, there were no significant differences in the VAS, ODI, and JOA scores between patients treated with CBT and PS
