Abstract

Transforaminal lumbar interbody fusion (TLIF) is widely used for lumbar instability due to spinal stenosis. However, procedures at the L3–L4 level present technical challenges and risk of L4 nerve injury. This study aimed to describe the clinical and radiological characteristics and evaluate outcomes of TLIF at L3–L4. Methods: A combined retrospective and prospective study was conducted on 91 patients undergoing decompression and L3–L4 TLIF fixation at the Spine Surgery Department, Viet Duc University Hospital, from January 2020 to May 2025. Results: Mean age was 54,8±6,2 years; females accounted for 57,1%. Degenerative etiology predominated (45.1%). Common symptoms were radicular pain (100%), step-off deformity (19,8%), positive Lasègue (85,7%), and sensory disturbance (100%). Imaging revealed disc space narrowing in 82,4%. Mean operative time was 102±24 minutes; complications <4%. VAS significantly decreased (back: 4,87→3,17; leg: 6,12→3,62). ODI improved from 55.7% to 22.5% after 12 months. Bone fusion progressed over time (grade I: 56%→17,6%; grade III: 13,2%→34,7%). Conclusions: L3–L4 spinal stenosis demonstrates distinct clinical and etiological features compared with lower levels, with a higher trauma-related rate. TLIF at this level provides favorable outcomes in pain reduction, functional recovery, and bone fusion quality
