load transmission between nail and bone, generating a moment that balances the bending effect appearing in
that zone.
With respect to the clinical follow-up, Table 11.5 shows the mean time of the fracture consolidation, except for Grade
3 in the “A” study, since it was not finally considered because only one case was assessed, and Grades 2 and 3 in the “B”
study, since there are no cases. Thus, for both studies, it can be observed that the healing time increases with higher
comminution grade.
In view of Table 11.5, the clinical results are in accordance with the FE simulations results, obtaining a longer healing
period for fractures with worse stability.
