“With [these] data, we see that the larger the head diameter, the lower the dislocation rate. Nevertheless, we are using these larger femoral heads judiciously using primarily 32 mm and 36 mm for a routine primary total hip. We are not advocating using 40-mm femoral head diameters for routine primaries due to risks of trunnionosis and corrosion, and unknown long-term wear rates.” said Kevin I.
