Abstract
A system for fixating a dysfunctional sacroiliac joint for SI joint fusion, the system including a sacroiliac joint implant, a sacroiliac joint screw or rod and a delivery tool configured for approaching a sacroiliac joint. The system may include an implant having a porous 3D matrix structure and may be manufactured by laser or electron beam additive manufacturing. The delivery tool may include a radiolucent material. The SI fusion system may further include custom sacroiliac joint implants, anchors, alignment tools or targeting arms manufactured for a particular patient. Pre-surgical imaging studies, including 3D rendering, and their interpretation may assist in planning desired trajectories, anchor dimensions and implant dimensions and may provide details specific to the manufacture of particular sacroiliac joint tools or implants and their implantation into the sacroiliac joint. The system may be configured for use with surgical robots and may include an integrated nerve monitoring and stimulation system.
