Methods of predicting vertebral body fractures of the lumbar spine

Table 1 Relative risk of incident vertebral fracture according shape of prevalent deformity

	Shape	Relative risk1
McCloskey-Kanis deformity type	Biconcavity	3.7
	Wedge	3.4
	Crush	4.4

¹Relative risk for an incident fracture of any shape according to the baseline deformity of a given shape-reference group consisted of subjects without prevalent deformity. Reproduced from Lunt et al[12].
