Background With the improvement of medical technology, the indications of spinal endoscopy technology are becoming more and more widespread. Percutaneous endoscopic posterior tranforaminal lumbar interbody fusion (Endo-P/TLIF) has been rapidly and widely used in lumbar spondylolisthesis combined with lumbar spinal stenosis, achieving certain efficacy in clinical observation. Compared with traditional fusion cages, height adjustable titanium fusion cage have better distraction effect and can effectively restore intervertebral space height, with obvious efficacy in Endo-P/TLIF surgery. Objective To investigate the application and clinical efficacy of Endo-P/TLIF combined with height adjustable titanium fusion cage in the treatment of lumbar spondylolisthesis with lumbar spinal stenosis. Methods The clinical data of 171 patients with lumbar spondylolisthesis with lumbar spinal stenosis treated at the First Affiliated Hospital of Guangxi University of Traditional Chinese Medicine from January 2019 to June 2021 were retrospectively analyzed. The included patients were divided into 35 cases in the Endo-P/TLIF+adjustable fusion cage group, 57 cases in the Endo-P/TLIF+ordinary fusion cage group, 47 cases in the Endo-TLIF+ordinary fusion cage group and 32 cases in the unilateral approach biportal endoscopic (UBE) +ordinary fusion cage group according to the operation mode. The gender, age, intraoperative bleeding, hospital stay, preoperative, immediate postoperative, 6-month postoperative and 12-month postoperative Oswestry disability index (ODI) score, visual analogue scale (VAS) score, Japanese Orthopaedic Association (JOA) score, degree of lumbar spondylolisthesis, lumbar lordosis angle, and dural cross-sectional area were compared among the four groups. Results There was no statistically significant difference in gender, age, operative time, intraoperative bleeding, and hospital stay among the four groups of patients (P>0.05). There was no interaction effect of group and time on ODI score, VAS score, JOA score, lumbar lordosis angle, and dural cross-sectional area (P>0.05) ; there was an interaction effect of group and time on the degree of lumbar spondylolisthesis (P |
