Angle changes in the Hybrid group. A: Segmental lordosis at L1-2, L2-3, L3-4, L5-S1 was preserved (p=0.39, p=0.49, p=0.07, and p=0.58, respectively), but lordosis at L4-5 was significantly decreased (p=0.02). B: Segmental angle at dynamic stabilized segment was decreased but it had no statistical significance (p=0.09) and lordosis at fused segment and adjacent segments was maintained in Hybrid group. C: Segmental ROM was generally decreased at all segment without statistical significance (all p>0.05). D: Segmental ROM at fused segment was significantly deceased (p=0.02). Segmental ROM at dynamic stabilized segment was increased without significance (p=0.05).
