The effect of impaction energy and bone quality on cementless femoral implant fixation and femoral periprosthetic fracture risk.

In both bone types, these differences were highly significant for both broaching (p = 0.001, p = 0.043, two-way ANOVA) and seating the implant (p < 0.001, p = 0.013, two-way ANOVA), respectively.

In terms of implant stability, the 30% difference observed between high and lower velocity impactions in normal bone failed to reach statistical significance owing to the wide variation between specimens.
