1) The total test execution Titanium (Ti6Al4V) and stainless steel (SUS 316L) pegs each three samples of commercially available products with substantive equality comparisons, this study found that the design, manufacture of bone screws plastic deformation, but not broken. In terms of maximum load: The design of the product titanium averaged about 89.3N, stainless steel averaged 65.4N, while commercial products L Brand (Ti Alloy) is 62.4N; stiffness aspects: the design of the product of titanium alloy (Ti6Al4V) an average of 172N / mm, stainless steel (SUS 316L) averaged 268.4N / mm, and a commercially available product L brand 102.7N / mm
