Table 7.

The mean values of segmental sagittal translatory motion of the lower lumbar spine as measured from flexion-extension radiographs at the last follow-up

Level	Direct repair (n=22)^a Translation (SD)[mm] (range)	Segmental fusion (n=23)^b Translation (SD)[mm] (range)	P value
L3–L4	1.5 (1.1) (0–5)	1.4 (1.0) (0–5)	NS
L4–L5	1.1 (0.9) (0–4)	1.7 (1.5) (0–6)	NS
L5–S1	0.6 (6) (0–3)	0 (0) (0)	0.002

NS Not significant

^aOnly L5 cases

^bIn four cases with L4–S1 fusion L2–L3, L3–L4, and L4–L5 were measured
