    摘要： Embodiments disclosed herein provide compression/distraction methods and tools useful for fitting a spinal stabilization system in a patient through minimally invasive surgery. The spinal stabilization system may comprise screws anchored in vertebrae. The vertebrae may need to be compressed or distracted. One embodiment of an instrument disclosed herein may comprise a shaft for engaging one of the screws through an extender sleeve. A driver may engage another screw through an opening of the instrument. Through this engagement, a surgeon may use the rack and pinion of the instrument to compress or distract one or more levels of the vertebrae in a parallel motion, which can be advantageous clinically in certain situations.

    摘要： Minimally invasive methods and instruments for reducing spinal stabilization rods into pedicle screws. In some embodiments, a method comprises positioning an instrument over a pedicle screw where a rod remains proud. A distal end of a first extension of the instrument is engaged with a collar of the pedicle screw. A second extension of the instrument is moved in translation relative to the first extension until a distal end of the second extension contacts the rod. This translation is accomplished by manipulating a pair of handles of the instrument. The rod is urged into the collar of the pedicle screw by application of force on the rod through the distal end of the second extension. The rod can be locked in the collar of the pedicle screw using a set screw passed through a passage in the first extension of the instrument.

    摘要： A system (10) and associated method are provided for mechanically fixating a region of a skull to a portion of a spine. A plate (20) is provided to contact a region of the skull and be secured thereto. A spinal rod (22) is configured to extend from a location adjacent the plate (20) to a location adjacent at least one vertebra (30). A variable connection (24) is provided to secure the rod (22) to the plate (20). The variable connection (24) has a first mode wherein the relative position of the rod (22) to the plate (20) can be adjusted and a second mode wherein the relative position of the rod (22) to the plate (20) is locked at a particular value selected to maintain a desired curvature of the spine.

    摘要： A poly-axial bone fastener assembly having a collar and a bone fastener can be coaxially locked to prevent poly-axial movements of the collar relative to the bone fastener while permitting the collar to rotate about an axis of the bone fastener, thereby combining the functions and advantages of a poly-axial bone screw and a fixed angle bone screw. Some embodiments of a coaxial locking mechanism may include a c-clip with a locking pin, a c-clip with hooks, a split ring with square corners, a pin that spins inside the collar, pins that travel about a neck of the bone fastener, a coaxially locking top that screws into the collar over a head of the bone fastener, and a top nut that threads onto the head of the bone fastener inside the collar to trap a flange of the collar between a shoulder of the bone fastener and the top nut.
