Abstract
The present subject disclosure provides a novel design for devices and methods for straightening a curved spine by using a reduction tool to move the spine with respect to an attached bone plate.
Claims20
A spinal reduction device, comprising:
- a base comprising an upper surface, a bottom plate-facing surface, a first side, a second side, a first end, and a second end;
- a vertical post coupled to the base and extending upwardly from the upper surface of the base, wherein the vertical post comprises an external thread;
- a translation nut configured to threadably engage the external thread of the vertical post;
- a plate attachment element extending away from the first side of the base in a direction away from the second side of the base and generally parallel to the bottom plate-facing surface of the base, the plate attachment element comprising a distal portion adapted to be visible to a user when viewed from above the base, the plate attachment element being adapted to engage with one or more attachment apertures in a bone plate;
- and
- a first guide extending upwards from the base adjacent the first end thereof, the first guide comprising a first guide passage with a longitudinal axis.

A system, comprising:
- a bone plate configured to couple to a spine in a patient, the bone plate comprising one or more attachment apertures and a bone screw hole extending therethrough;
- and
- a spinal reduction device configured to couple to the bone plate, the spinal reduction device comprising:
- a base having an upper surface, a bottom plate-facing surface, a first side, a second side, a first end, and a second end;
- a vertical post coupled to the base and extending upward from the upper surface of the base, wherein the vertical post comprises an external thread;
- a translation nut configured to threadably engage the external thread of the vertical post;
- a plate attachment element coupled to the bottom plate-facing surface of the base and configured to engage the attachment aperture of the bone plate, wherein the plate attachment element comprises a distal portion adapted to be visible to a user when viewed from above the base;
- and
- a first guide extending upwards from the base adjacent the first end thereof, wherein the first guide comprises a first guide passage having a longitudinal axis.
