A feasibility study of individual 3D-printed navigation template for the deep external fixator pin position on the iliac crest

Table 2 Material parameters of the model

Items	Young’s modulus (MPa)	Poisson’s ratio	Element type
Pelvis
Cortical part	12,000 [10]	0.3 [10]	S3
Spongy part	100 [10]	0.2 [10]	C3D4
Sacrum	12,000 [10]^a	0.3 [10]^a	C3D4
Fixator pin	200,000 [11]	0.28 [11]	C3D4

^aBecause the sacrum was treated to be only consisted of cortical bone, its materials parameters were set as the cortical part in pelvis
