    Abstract: A rod bender includes a ram shaft, having a distal end with an arcuate rod contact surface, that is movable along a shaft path that passes between two rollers, each having a curved roller surface. Each of the rollers is positionable, in an analog manner, at a variety of positions along a respective roller path, relative to a distal position of the arcuate rod contact surface. A straight rod, positioned against the rollers so that it spans the space separating the rollers and crosses the shaft path, can be rammed with the ram shaft so that the rod is bent into an arc. The rod is bent as the movement of the ram shaft pushes the arcuate rod contact surface forward against the center of the rod, while the curved roller surfaces prevent corresponding forward movement of the lateral portions of the rod.

    Abstract: A polyaxial orthopedic device for use with rod implant apparatus includes a screw having a curvate head, a two-piece interlocking coupling element which mounts about the curvate head, and a rod receiving cylindrical body member having a tapered socket into which both the screw and the interlocking coupling element are securely nested. The interlocking coupling element includes a socket portion which is slotted and tapered so that when it is radially compressed by being driven downwardly into the tapered socket in the cylindrical body it crush locks to the screw. The securing of the rod in the body member provides the necessary downward force onto the socket portion through a contact force on the top of the cap portion. Prior to the rod being inserted, therefore, the screw head remains polyaxially free with respect to the coupling element and the body. In a preferred embodiment, the cap portion and the socket portion are formed and coupled in such a way that when the cap portion is compressed toward the socket portion, there is an additional inward radial force applied by the cap portion to the socket portion, thereby enhancing the total locking force onto the head of the screw.
