Abstract
Objective : This study investigated the clinical and radiological outcomes of lumbar spinous process-splitting laminectomy (LSPSL) performed to treat lumbar spinal stenosis at a single institution in Korea.

Methods : A retrospective review was conducted of patients who underwent LSPSL for lumbar spinal stenosis between June 2020 and February 2022, with a minimum 1-year follow-up. Clinical outcomes were assessed using the visual analogue scale (VAS), Oswestry Disability Index (ODI), European quality of life - 5 dimensions - 5 levels (EQ-5D-5L), European quality of life VAS (EQ-VAS), and modified MacNab criteria. One year after surgery, radiological outcomes were evaluated through computed tomography scan to assess the spinolaminar bone union rate and patterns.

Results : Out of 38 patients, data from 30 patients (male:female=17:13) and 36 surgical levels were analyzed. The mean age was 67 years (range, 46?88 years). The preoperative mean leg VAS score and ODI significantly decreased at the 1-year postoperative follow-up (leg VAS, 6.6?3.8; p=0.001; ODI, 19.3?10.9, p=0.006). The EQ-5D-5L index and EQ-VAS also significantly improved (0.52?0.77, p<0.001; 50.8?67.1, p=0.018; respectively). Using the modified MacNab criteria, the study reported excellent and good outcomes in 80% of patients at the 1-year follow-up, with no serious complications observed. The overall spinolaminar union rate was 77.8% (complete union, 58.3%; partial union 19.4%).

Conclusion : LSPSL was found to provide favorable clinical outcomes and a satisfactory rate of posterior bony structure restoration for lumbar spinal stenosis, making it a feasible treatment option.
