For lumbar spinal canal stenosis, we only perform minimally invasive decompression surgery in all patients with or without degenerative spondylolisthesis. The aim of this study was to examine and validate the 1-year results of patients who underwent decompression surgery only, focusing on the presence or absence of degenerative spondylolisthesis.
Methods: 200 patients with lumbar spinal canal stenosis operated on only the L4/5 vertebrae were divided into 85 patients in the non-degenerative spondylolisthesis group (NDS group), 95 patients in the Meyerding classification 1st degree group (DS1 group) and 20 patients in the 2nd degree group (DS2 group). Operative technique, operative time, blood loss, perioperative complications, reoperation rate, JOA score, ODI, JOABPEQ and Lumbago/lower limb pain NRS were compared.
Results: There were no differences in operative time or blood loss between the three groups. There was one dural injury in the DS1 group and one re-operation in the NDS group; JOA score and JOABPEQ did not differ between the three groups; DS2 group had inferior results in postoperative ODI and lower limb NRS; DS2 group had some inferior results. However, the DS2 group was considered to have a good surgical outcome based on the reoperation rate, the improvement in ODI and the significant improvement in lower limb pain NRS. The presence or absence of a spondylolisthesis was less involved in the short-term results and did not suggest the need for fusion surgery.
