Abstract
A system for reducing deformities in the spine includes a first tower assembly and a second tower assembly. The first tower assembly includes a first tower that couples to a first screw in a first vertebral level, a load transfer ring rotatable coupled to the first tower, and a load transfer link rotatably coupled to the load transfer ring. The second tower assembly includes a second tower that couples to a second screw in a second vertebral level, a load applicator secured to the second tower, and a load transfer member rotatably coupled to the second tower and linked to the load transfer link. The load applicator applies force to the load transfer member to position the first tower assembly relative to the second tower assembly.
