A multi-centric orthopedic joint having inner and outer guide plates and
upper and lower arms rotatably connected to the guide plates for pivotal
movement therebetween. The plates each include upper and lower pairs of
curved bean shaped slots, tilted relative to one another. The arms
include a proximal end, the proximal end further including pins
positioned and proportioned for complimental sliding movement within the
upper and lower slots of the guide plates. Set screws are positioned
between the inner and outer guide plate against a locking surface of the
proximal end of each arm. When the set screws are loosened the upper and
lower arms may be moved relative to one another, permitting the guide
pins to slide within the slots but in opposite directions relative to one
another. Flat-screws secure the inner and outer guide plates and co-act
with the set screws as a locking mechanism of proximal ends of said arms
at a desired angulation between them.
