Head
Femoral
heads are often truncated for manufacturing convenience since
it is easier to grind and polish truncated heads. Unfortunately,
such truncation reduces the spherical surface available to
resist bipolar cup dislocation and can introduce undesirable
stress risers in the UHMWPe bearing thereby increasing wear
and possibly pitting the bearing surface.
Endotec's
proprietary machining and polishing processes allow maintenance
of the maximum amount of spherical surface avoiding problems
associated with truncation and providing maximum resistance
against bipolar cup separation.
