Background. Spondylolisthesis is the forward slippage of the upper to the lower vertebrae, which affects spinal cord. Spinal fusion is an important method for the stability of the spine leading to pain and disability reduction in patients with chronic low back pain in spondylolisthesis. The aim of this study was to evaluate postoperative changes in spinopelvic parameters, pain, and disability in low-grade spondylolisthesis patients undergoing posterior lateral fusion (PLF) and posterior lateral interbody fusion (PLIF). Materials and methods. In the present study, 68 patients who underwent PLF and PLIF due to low-grade spon-dylolisthesis were recruited. The spinopelvic parameters, visual analogue scale (VAS) score and Oswestry disability index (ODI) before and after surgery were compared. Results. Pelvic tilt (PT) decreased in both groups after surgery, with more significant decline in PLIF group. More-over, the mean of PT returned to normal value at both groups. There was also a significant decline in both VAS score and ODI parameters between the two groups. There was a correlation between VAS score and postoperative PT changes. However, the pelvic incidence, lumbar lordosis (PI-LL) and VAS score index did not differ significantly between the two groups after surgery. Conclusion. Both PLF and PLIF in low-grade spondylolisthesis patients are useful in restoring PT and pelvic sta-bility, but there is no significant difference in the postoperative pain and disability of patients in the two methods.
