43. Minimally invasive transforaminal lumbar interbody fusion for single-level lumbosacral spondylolisthesis with intraoperative monitoring
Main Article Content
Abstract
Minimally invasive surgery transforaminal lumbar interbody fusion (MIS TLIF) was considered a promising treatment in lumbosacral spondylolisthesis, with small incisions, faster recovery, and intraoperative monitoring providing safer and less complication for patients. From 2022 to December 2024, 50 single-level lumbosacral spondylolisthesis were performed MIS TLIF with intraoperative neuromonitoring. All information was recorded: perioperative and follow-up, demographic data, operation time, blood loss, VAS, ODI, modified MacNab criteria, radiographic evaluation, and complications. 50 patients were followed up for 12 months. Mean age: 52.1 and mean follow-up 12 months. VAS back pain: 7.3 preoperatively and 1.3 at the final. VAS of leg pain was 6.7 preoperatively and 1.4 at the final. ODI was 56.4% preoperatively and 17.1% at the final. MIS-TLIF was associated with a good reduction of spondylolisthesis, an increase in disc height (+3,7mm), foraminal height (+3mm), and segmental lordosis (+3°). Pelvic parameters were not significantly changed. Mean blood loss was 85ml. The mean time of surgery was 84.9 mins. The mean time for first walking was 1.2 days and the mean discharge time was 5.2 days. There were no complications perioperatively. Clinical improvement was significant after 6 months follow-up, from 6 to 12 months follow-up symptoms were imperceptibly changed. According to the modified MacNab criteria: 75% excellent, 20% good, and 5% fair. The MIS TLIF with intraoperative monitoring provides safe results, less operative time, and faster recovery with a high satisfaction rate.
