surgery of human spine deftly performed involves super-humans using super-alloys. rods of 4-6 mm diameter link
surgical screws--pedicle screws-- together in a ridgid chain intended for lifetime presence--problem--traditional rod composition
of titanium or cobalt chrome have fracture failure of 22%--
so a new alloy put in use 5 years ago claims fracture proof --many thousands now in use with zero fracture failure
composition-- molybdenum rhenium--maker recently announced lifetime hardware replacement if failure occurs
Princess Eugenie is good natured enough to display her xray rod architecture on operating table face down tracheal tube in place
