38.2% v. 13.4%), and the standing DLS-disc angle was greater in the decompression group (6.2° v. 5.0°, p = 0.012).Over time, mean slip percent did not change in the decompression group and improved in the fusion group from 25% to 16%.Lumbar lordosis increased from preoperative values at 3 months and remained higher through 5 years favouring fusion by 2.6° to 3.1° (p ≤ 0.016).Sagittal vertical axis improvement favoured fusion at 3 and 12 months (-13.1 mm and -15.00 mm, p ≤ 0.01) but was not significant at 2 or 5 years.Other parameters showed no significant changes over time or differential trajectories by surgery type.Conclusion: Short-segment fusion produced modest improvements in sagittal alignment compared to decompression alone, but the effect tended to nullify after 24 months.Both techniques maintained mean disc height and adjacent segment stability, as well as slip segment stability for the decompression group up to 5 years.
