Progression of vertebral deformity of prevalent vertebral fractures in the elderly: a population-based study

Table 2 Baseline characteristics of vertebral deformity

Deformity Grade	Number of VFs	Spinal level			Deformity type
Deformity Grade	Number of VFs	Thoracic	Thoracolumbar	Lumbar	Wedge	Biconcave	Crush
G1	170 (85)	40 (23.5)	104 (61.2)	26 (15.3)	126 (74.1)	29 (17.1)	15 (8.8)
G2	17 (8.5)	2 (11.8)	12 (70.6)	3 (17.6)	9 (52.9)	5 (29.4)	3 (17.6)
G3	13 (6.6)	6 (46.2)	6 (46.2)	1 (7.7)	11 (84.6)	2 (15.4)	0 (0)
Total	200	48 (24.0)	122 (61.0)	30 (15.0)	146 (73.0)	36 (18.0)	18 (9.0)

The extent (G1: mild, G2: moderate, G3: severe) and type (wedge, biconcave, crush) of prevalent vertebral fractures (VFs) were evaluated using Genant’s semi-quantitative method [11]. The spinal levels were divided into three groups: thoracic (T4-T9), thoracolumbar (T10-L2), and lumbar (L3-L4). The numbers in parentheses indicate percentages
