Abstract:
A bone screw extension assembly for use in placing a connecting rod percutaneously into tissue of a patient comprises a multi-axial bone screw and a screw extension releasably coupled to yoke of the bone screw. The screw extension includes coaxially disposed outer sleeve and inner sleeves that are rotatable relative to each other. A screw engaging member projects radially from the distal end of the inner sleeve and is configured to engage an extension coupling surface on the outer sleeve upon relative rotation of the inner and outer sleeves. A securement member including cooperative surfaces is defined adjacent the distal end of the inner and outer sleeves that is operable upon relative rotation of the inner sleeve and outer sleeve to radially secure the sleeves together to thereby maintain the engagement of the screw engaging member and the bone screw.

Claim (Index 8):
In combination for use during spinal surgery,\n a multi-axial bone screw including a shaft having a threaded screw portion, a screw head and a yoke articulatingly attached to said screw head, said yoke having an exterior surface and a slot therethrough for receiving a connecting rod, said slot defined by a pair of upstanding arms having opposed interior surfaces, said yoke having an extension attachment surface thereon; an elongate hollow screw extension having a distal end and a proximal end, the extension being releasably attached to said multi-axial bone screw at said extension attachment surface on said yoke, said extension including a persuader coupling member on an outer surface of said elongate hollow screw extension; and a rod persuader including an elongate member releasably coupled to said persuader coupling member for axial movement relative to said screw extension independently of and without affecting the engagement of said screw engaging member of said extension with the extension coupling surface on said yoke, said persuader member having a distal end defining an axially movable rod engaging surface disposed in a first axial position to allow a rod to be operably movable in cooperation with said persuader coupling member to a second axial position to urge a rod into the slot of said yoke, said rod persuader elongate member including on an interior surface thereof a coupling element releasably coupled directly to said persuader coupling member, said coupling element being configured to couple to and decouple from said persuader coupling member, said rod persuader elongate member including an advancement mechanism operable to axially move said rod persuader member relative to said screw extension.
