Abstract:
1. A spinal fusion implant for fusing together two adjacent vertebra comprising: a first member having first and second opposing sides and a first bore defining a first central longitudinal axis, the first bore being in communication with at least the first side; a second member having third and fourth opposing sides and a second bore in communication with at least the third side, the second bore defining a second central longitudinal axis, the first and second axes forming a first pair; and an elongated first pin located in the first and second bores for securing the first member to the second member at the interface formed by the facing first and third respective sides to thereby form said spinal fusion implant, the pin having first and second sections and at least one first outermost peripheral surface defining a first transverse dimension therebetween at the first section defining a third central longitudinal axis, the pin having at least one second outermost peripheral surface defining a second transverse dimension therebetween at the second section defining a fourth central longitudinal axis, the third and fourth axes forming a second pair; one axis of at least one of the first and second pair of axes being offset relative to the other axis of the at least one pair of axes so as to place the pin in relative compression and tension in the first and second bores for providing a compressive load on the surface of the first and second bores to frictionally secure the members together.
