Abstract
Spinal rod reduction apparatuses, systems, and methods are provided. In various examples, a rod reduction apparatus includes a first threaded member (130, 210, 330) including an engagement feature (138A, 138B, 220, 332, 334) configured to selectively anchor the first threaded member to the implantable screw assembly. A second threaded member (110, 230, 310) is configured to threadably engage with the first threaded member. The second threaded member is axially movable with respect to the first threaded member with rotation of the second threaded member. A spinal rod urging member (120, 240, 320) is axially movable with the second threaded member. The urging member includes a bearing surface (126, 242, 320) that is configured to selectively abut the spinal rod and selectively urge the spinal rod toward the implantable screw assembly with rotation of the second threaded member in a first rotational direction.
