ABSTRACT:
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.
