METHOD AND INSTRUMENTATION FOR IMPLANT INSERTION

摘要

An apparatus for facilitating fusion of adjacent vertebrae includes an insertion tool including an elongated member defining a longitudinal axis an d having a proximal end and a distal end, and a mounting portion disposed at the distal end thereof. A fusion implant is releasably mounted to the insertion tool, the fusion impla nt including a cage body defining a longitudinal bore, the cage body positionable about the mounting portion. At least one of the mounting portion of the insertion tool and the cage body of the fusion implant includes a rail extending in a longitudinal direction and the other of the mounting portion and the cage body includes a groove extending in the longitudinal direction and being correspondingly dimensioned to receive the rail, to thereby prevent relative rotational movement of the insertion tool and the fusion implant.
