Finite element analyses predict the mechanical impact of cam-FAI surgery on ovine femurs

ConclusionsMore than 80% of the initial strength is preserved after a 36% neck resection.This is consistent with human data [3].FE models catch the weakening of ovine femurs.The larger influence of the resection size may be due to modelling simplifications (cortex, trabecular orientation, material law).The predictive value of the FE models is comparable to what is being done for intact human femurs (r 2 =0.82-0.95)[4,5].
