BACKGROUND Lumbar fusion and internal fixation techniques have shown promise in treating lumbar disc herniation (LDH), yet the impact on lumbar function in young patients remains unclear. This study aimed to investigate the impact of lumbar fusion on lumbar function in young patients. MATERIAL AND METHODS A retrospective analysis was conducted on 330 patients diagnosed with LDH admitted to our hospital. Patients were divided into 2 groups: a control group (n=264) that underwent a minimally invasive procedure with a keyhole lens, and a research group (n=66) that underwent lumbar fusion internal fixation. Clinical features and therapeutic outcomes were assessed using Oswestry Disability Index (ODI) and Japanese Orthopedic Association (JOA) Lumbar Scores before surgery and 12 months postoperatively. Additionally, intervertebral space height, degree of vertebral spondylolisthesis (grades I, II, and III), incidence of adverse effects, and treatment efficacy were measured pre-and post-surgically. RESULTS No significant difference in ODI and JOA scores was found between the groups before surgery (P>0.05). Postoperatively, the research group had lower ODI scores, higher JOA scores, and lower intervertebral space heights compared to the control group (P=0.001). While grade 1 and 2 spondylolisthesis showed slight improvement (P>0.05), a significant difference was observed in grade III spondylolisthesis between the 2 groups (P=0.001). Additionally, the research group had a lower incidence of adverse effects (P=0.049) and higher treatment efficacy, although the difference was not statistically significant (P>0.05). CONCLUSIONS Lumbar fusion with internal fixation produced better postoperative outcomes and fewer adverse effects than minimally invasive procedures in young patients with lumbar disc herniation.
