RingLoc : Unparalleled
locking technology
®
Biomet’s RingLoc® acetabular components have
redefined the standard of acetabular technology.
Testing by independent laboratories has rated
RingLoc® technology among the highest in terms of
push-out, lever-out and congruity of the implant as well
as the lowest in micromotion.2–5
Unparalleled RingLoc® locking technology
Achieves maximum push-out and lever-out
strength with lowest micromotion of
independently tested competitive systems2–5
Fully congruent design
Maximizes congruency at the
liner-to-shell interface to help
minimize micromotion
