I doubt that his titanium pin has any comparison to a THR, jigger. Those pins are known to extrude through the bone from time to time and mostly it's because the where the bone was broken, as it heals it shrinks and the pin becomes too long. Since it is fixed at the end with screws, it has no choice but to push through the bone. And he wouldn't have contributed to it by 'overdoing it'. The mechanics just don't work that way.
So please don't worry yourself so, it's unnecessary.
