Table 1 Value of cortical and cancellous bones and titanium (titanium was used in all implant conditions, including the locking plate, fixation screws and percutaneous cannulated screws).

Material	Young’s modulus (MPa)	Poisson’s ratio
Cancellous bone	700	0.20
Cortical bone	17000	0.30
Titanium	106000	0.33
