Abstract:
1. A spine stabilization rod assembly, comprising: a rod having a one-piece construction, and a substantially straight longitudinal axis, wherein the rod has a reduced diameter segment between two opposing end segments thereof such that a shoulder is defined between the reduced diameter segment and each one of the end segments; and a sleeve member positioned over the reduced diameter segment of the rod, wherein the sleeve member is positioned over the reduced diameter segment of the rod by relative displacement of the rod through a central passage of the sleeve member, wherein only opposing end portions of the sleeve member are deformed such that translation of the sleeve along the rod causes an end portion of the sleeve to engage a corresponding one of the shoulders for limiting such translation and such that an entire portion of an inner surface of the central passage of the sleeve member between said deformed opposing end portions of the sleeve member is spaced away from an entire underlying portion of the reduced diameter segment of the rod after the opposing end portions thereof are deformed.
