US 2020/0261123 A1 · METHODS AND INSTRUMENTS FOR PERFORMING LEVERAGED REDUCTION DURING SINGLE POSITION SPINE SURGERY

Abstract

A spinal procedure includes attaching a first reduction instrument to a first guide assembly and a second guide assembly. The first reduction instrument includes a fixed attachment assembly and a translating attachment assembly that cooperatively interfaces the fixed attachment assembly. The first guide assembly is attached to a first pedicle and the second guide assembly is attached to a second pedicle. The first reduction instrument is moved to reduce an orientation of the spine, while imaging a reduction of the orientation of the spine. An angle and position of the first reduction instrument is locked upon achieving a desired reduction. The spine may then be fused.
