Table 3

Radiographic measurements of anterior vertebral height and kyphotic angle (n = 29, mean ± standard deviation).

	Preoperation	Postop 1 day	Postop 6 months	Last follow-up
Anterior vertebral height (mm)	14.17 ± 2.32	19.53 ± 2.77	19.48 ± 2.83	19.36 ± 2.79
Kyphotic angle (°)	18.55 ± 4.47	12.07 ± 3.23	12.16 ± 3.51	12.33 ± 3.39

Note., data at each time point postoperatively vs. preoperative data; the kyphotic angle was marked with black lines in Figure 2(a); last follow-up occurred at 19.6 months on average, ranging from 16 to 24 months.
