Evaluate the surgical outcomes of lumbar-sacral fusion for spondylolisthesis.. Objects and Methods: evaluate the surgical outcomes of lumbar-sacral fusion for spondylolisthesis. Results: There were 73 patients in our study group, with a male-to-female ratio of 1:2 (male: 32.9%, female: 67.1%). The age group 50-59 years had the highest proportion at 27.4%. The average VAS (Visual Analogue Scale) scores for back and leg pain decreased from 6.11 and 4.55 to 2.81 and 1.61 at discharge, respectively. The degree of correction showed that 56 patients (76.7%) were corrected to grade 0 slippage, and there were no cases of grade III slippage postoperatively. All screws (100%) were placed according to Lonstein's criteria. The placement of the graft (2/3 anterior to the vertebral body) was correct in 97.3% of cases, with no dislocations reported. At 6 months post-operation, the VAS score for back pain significantly improved (P<0.05). Additionally, 78.7% of patients achieved grade 2 bone UNI0N at 6 months post-operation. Conclusion: Lumbar-sacral fusion surgery is an effective treatment for spondylolisthesis, providing pain relief, a high rate of bone fusion, and a low risk of complications.
