摘要： An instrument for compression and distraction of a vertebral segment and reducing a surgical rod includes a first arm, a second arm, a coupler, and a reducer. The first arm includes a first aperture for receiving a first screw extender that attaches to a first vertebra. The second arm pivotably couples to the first arm and includes a second aperture for receiving a second screw extender that attaches to a second vertebra. The coupler links the first arm to the second arm to position the first arm relative to the second arm for compression and distraction of the first vertebra relative to the second vertebra. The reducer is received within the second aperture for reducing a surgical rod within the second screw extender.

摘要： 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.

摘要： A polyaxial screw head remobilizer system for remobilizing a screw body member relative to a head of a polyaxial bone screw includes a barrel body, a handle assembly, an inner shaft, a slide assembly, and a lever. The barrel body includes proximal and distal ends. The distal end includes a plurality of prongs for releasably engaging a plurality of yokes of the polyaxial screw body member to center the inner shaft over the head of the screw. The handle assembly couples to the proximal end of the barrel body. The inner shaft, disposed within the barrel body, includes proximal and distal ends. An engagement feature of the inner shaft mates with pockets of a bushing of the screw body member. The slide assembly is operably coupled to the barrel body and effect translations of the inner shaft. The lever extends from the slide assembly and rotates to actuate the slide assembly.

摘要： A nested dilation tube assembly for enabling implantation of a spinal screw assembly into a vertebrae is provided. The dilation tube assembly includes a plurality of dilation tubes. Each dilation tube includes an elongated cylindrical shaft with an outer diameter slightly larger than a preceding dilation tube. After being inserting into a body, the plurality of dilation tubes form a nested, concentric assembly enabling an opening placed in the spinal area and/or vertebrae to be enlarged up to the outer diameter of a last dilation tube. The inner dilation tubes are capable of being removed from outer dilation tubes such that the inner diameter of an inner most remaining dilation tube forms a space for receiving instruments and/or assemblies.
