Table 4.

Fracture load and cortical thickness ratios between distal and proximal crack surfaces and the average crack surface of three bone models. Ratios of cortical to whole bone fracture load at the average, distal and proximal crack surfaces. Bone Model 1, 2, and 3 refer to the three randomly selected bone models that were used to evaluate the influence of the crack location.
