Describe the outcomes of lateral lumbar interbody fusion and posterior spinal fusion surgery for the treatment of degenerative lumbar scoliosis. Subjects and methods: A descriptive study of 54 cases of patients with degenerative lumbar scoliosis received lateral lumbar interbody fusion and posterior fusion at Viet Duc Hospital. Results: 54 patients (36 females, 18 males) with a mean age of 57.47 ± 10.32. The postoperative outcomes were evaluated using the Macnab criteria at the 12-month follow-up with all 54 patients (100%) attending the follow-up visit: excellent: 50 (92.6%), good: 3 (5.55%), fair: 1 (1.85%), poor: 0 (0.0%). The improvement in clinical symptoms at the final follow-up visit was assessed using the Visual Analog Scale (VAS) for back pain and leg pain before the surgery and at the 12-month postoperative period, with scores of 1.20 ± 1.00 and 1.15 ± 1.15, respectively. The functional assessment using the Oswestry Disability Index (ODI) before the surgery and at the 12-month postoperative period was 6.08 ± 4.61. The postoperative radiographic evaluation at the 12-month follow-up showed that the average scoliosis angle before the surgery and at the 12-month postoperative period was 4.24 ± 1.56, and the average kyphosis angle before the surgery and at the 12-month postoperative period was 20.58 ± 5.74. According to the Bridwell criteria, the fusion rate at the 12-month follow-up was 96.3% for Grade I fusion and 3.7% for Grade II fusion. Conclusion: Lateral lumbar interbody fusion and posterior fusion surgery is a safe and effective method for treating degenerative lumbar scoliosis.
