Abstract
A spinal stabilization system, method, and a surgical kit having a surgical extender apparatus for implanting a surgical screw are disclosed. The extender includes a housing having a distal end and a proximal end, a hollow interior passageway disposed between the distal end and the proximal end, a channel disposed along an exterior surface of the housing at least partially between the distal end and the proximal end and configured to at least partially expose the hollow interior passageway, an interior locking mechanism disposed on an interior surface of the housing and substantially adjacent the proximal end, wherein the interior locking mechanism is configured to allow attachment of at least one surgical tool, and at least one flexible member disposed substantially adjacent the distal end. The housing is configured to accommodate placement of a surgical screw implant. The surgical screw implant is secured to the housing using a mating feature in the surgical screw implant. The at least one flexible member is configured to retain the surgical screw implant. The mating feature is configured to control axial movement of the surgical screw implant.
