The present invention provides a spinal correction device comprising: a pedicle screw comprising a seating part having a pair of first slits formed opposite to each other, and a screw part disposed at one side of the seating part so as to be implanted into a bone; an extender having a pair of second slits for guiding a rod so as to seat same in the seating part, and detachably fastened at one side thereof to the outer surface of the seating part; a reduction body detachably fastened to the other side of the extender; and a rod reducer arranged to pass through the reduction body and the extender so as to fix the rod placed in the pair of second slits by pressing the rod against the seating part.

A tool set for implanting bone screws in a human spine, followed by the implantation of a rod into the bone screws includes end guide tools having flexible back wall flaps that receive opposite ends of the rod and intermediate guide tools that hold the rod in intermediate locations between the end guide tools. Both the end and intermediate guide tools include an attachment structure for operably connecting the guide tool to a bone screw. The attachment structure includes an undercut and/or recess so as to resist splaying and separation of the guide tool from an attached bone screw.

Implants, systems, and methods for securing a flexible band, thereby providing a desired correction to the spine. The implant may secure the flexible band to a spinal rod and/or a pedicle screw. The implant has a locking mechanism to secure the band. The band may be looped around bony anatomy and tensioned to achieve correction and provide fixation as an alternative or supplement to pedicle screws and spinal rods during spinal deformity surgery.

A method is provided for planning, performing, and assessing of surgical correction to the spine during a spinal surgical procedure. This method is implemented by a control unit through a GUI to digitize screw locations, digitize anatomical reference points, accept one or more correction inputs, and generate one or more rod solution outputs shaped to engage the screws at locations distinct from the originally digitized locations.

Kerrison-style rod reducers, inline-style rod reducers, and related methods of using the disclosed rod reducers for holding a spinal implant and seating a fixation rod in a rod-receiving portion of the spinal implant are provided for herein. The disclosed rod reducers can also be configured for applying a set screw or other closure mechanism to secure the rod within the rod-receiving portion of the spinal implant. The disclosed embodiments can be easy to use, not require significant force to operate, and be efficient, thereby reducing the time and expense necessary to perform spinal surgery. The disclosed rod reducers can be readily dissembled, thereby making these surgical instruments easy to clean and sterilize.

A tool set for implanting a rod in a human spine in conjunction with bone screws. The tool set includes a pair of end guide tools that receive opposite ends of the rod in channels and under manipulation by a surgeon facilitate transport of the rod toward the bone screws attached to the guide tools. Intermediate guide tools having guiding pass through slots are utilized to guide intermediate locations along the rod toward associated bone screws. An attachment structure operably connects the guide tools to the bone screws. The guide tools each include a lower guide and advancement structure to allow a closure top with mating structure to be rotated and driven downward against the rod and to cooperate with similar structure in the bone screw to seat and lock the rod therein. A method utilizing the tool set allows a surgeon to percutaneously implant the rod in the patient.

A multi-stage minimally invasive surgical procedure and associated instruments are disclosed. First, the surgical site is prepared. After preparation, the bone screws or anchors are attached to the bone. Subsequent to insertion of the screws, a rod or connecting member is positioned within the yoke portion of the bone screw. Caps are then placed in a pre-lock position within the yokes. The bone screws may be compressed together or distracted along the rod or connecting member, thereby setting the final spacing of the bones or bone segments. Finally the caps are moved to a final lock position to fix the screws to the rod or connecting member to maintain the bones in position relative to each other.
