Evaluation of surgical treatment results in elderly patients with lumbar spinal stenosis

Abstract

Background: Lumbar spinal stenosis in elderly patients is a common pathology and the biggest cause of the indication for spinal surgery. Our aims are to study clinical and subclinical characteristics and evaluate TLIF surgery results in elderly patients with lumbar spinal stenosis. Materials & methods: A total of 45 lumbar spinal stenosis patients were treated with TLIF surgery from June 2018 to March 2021. Using a follow-up, clinical descriptive research method. Evaluate before surgery and follow up until 1 year after operation. Results: The average age was 67.96 ± 5.701. The classification of patients admitted to hospital was 33.3% crippled and 66.7% paralyzed according to the ODI. MRI showed 91.1% absolute stenosis, 8,9% relative stenosis. There were no surgical accidents. The complication rate after surgery was 6.6%. 12 months after surgery, VAS back pain decreased to 1.16 ± 1.33, VAS leg pain decreased to 0.80 ± 0.99, JOA increased to 23.73 ± 3.61, ODI decreased to 26.89 ± 10.98. 93.3% recovery rate classified as excellent and good according to Hirabayashi. Conclusions: TLIF surgery on elderly patients brought good results.
