Figure 5

Intervertebral displacement of L3–L4 segment under flexion and extension motions (8400 N-mm). Intervertebral displacement between three different decompressive procedures under extension motion did not significantly differ (P > 0.05). However, under flexion motion, intervertebral displacement in the laminectomy group was statistically higher than in the intact or bilateral laminotomy groups (P < 0.05).
