  • Patent number: 10499957
    Abstract: A polyaxial pedicle screw includes a housing, a bone screw member, and an anvil. The bone screw member includes a head and a threaded shaft extending from the head. The head is selectively securable within the housing. The anvil is positionable within the housing adjacent to the head of the bone screw member when the anvil and the head of the bone screw member are positioned within the housing. The anvil may define one or more grooves in an outer surface of the anvil. The groove defines a flap that is flexibly attached to the anvil to enable the anvil to flex an amount sufficient to maintain the head of the bone screw in constant contact with the anvil when the bone screw member is moved relative to the anvil. A rod reducer may be secured to the polyaxial pedicle screw to secure a spinal rod within the housing.

  • Patent number: 9820779
    Abstract: A spinal stabilization system includes a connecting rod, a rod bending device, and a plurality of bone screws. The connecting rod includes an elongate round portion, an elongate head portion and a neck portion connecting the elongate round portion with the elongate head portion. The rod bending device includes an elongate body defining an aperture configured and dimensioned to receive the connecting rod therethrough in a single orientation. The bone screws include a housing portion and a screw shaft distally extending from the housing portion. The housing portion includes an inner housing and an outer housing slidably surrounding at least a portion of the inner housing. The inner housing defines a slot configured and dimensioned to releasably secure the elongate round portion of the connecting rod therein. The outer housing is movable relative to the inner housing between an unlocked state and a locked state.

  • Patent number: 9468476
    Abstract: Systems and methods for surgical spinal correction are disclosed. A system including a plurality of bone screws, spinal rods, manipulators, and/or transverse couplers is disclosed for the manipulation of the spinal column is disclosed. A method of achieving, in a single action, manipulation and/or rotation of the spinal column using the disclosed system is disclosed. Also disclosed is a method of conducting spinal surgery to correct spinal deformities wherein spinal rods are pre-bent in a physiological sagittal plane prior to attachment of the vertebrae using bone screws.

  • Patent number: 9414860
    Abstract: A manipulation device includes a body portion, a plurality of articulatable legs, and at least one lock member. The legs extend from the body portion. Each of the legs is configured to engage a surgical instrument at a distal end thereof. Each of the legs is transitionable between an unlocked condition, wherein the leg is free to articulate, and a locked condition, wherein the leg is fixed in position. The at least one lock member is operably disposed within the body portion and is coupled to at least one of the articulatable legs. The lock member is rotatable relative to the body portion between an unlocked position and a locked position for transitioning the at least one articulatable leg coupled thereto between the unlocked condition and the locked condition.

  • Patent number: 9393048
    Abstract: A bone screw assembly includes a screw, an outer housing, and an inner housing. The screw includes a shank and a head. The outer housing has a proximal end, a distal end, and a passageway extending longitudinally therethrough. The outer housing defines a saddle at the proximal end thereof for receiving at least a portion of a rod therein. The inner housing is positionable within the passageway of the outer housing. The inner housing has a recessed distal portion for receiving the head of the screw therein. The inner housing also includes a proximal surface defining a substantially V-shaped configuration for receiving rods of different diameters therein.
