SYSTEMS AND METHODS FOR THE FUSION OF THE SACRAL-ILIAC JOINT

摘要

The sacral-iliac joint between an iliac and a sacrum is fused either by the creation of a lateral insertion path laterally through the ilium, through the sacral-iliac joint, and into the sacrum, or by the creation of a postero-lateral insertion path entering from a posterior iliac spine of an ilium, angling through the sacral-iliac joint, and terminating in the sacral alae. A bone fixation implant is inserted through the insertion path and anchored in the interior region of the sacrum or sacral alea to fixate the sacral-iliac joint.

主权项

1. A system for creating a bore through the ileum, across the sacroiliac joint, and into the sacrum to receive an implant having a rectilinear cross-sectional profile, the system comprising:
a drill bit having a longitudinal axis and a cross-sectional profile transverse to the longitudinal axis of the drill bit; and a broach having longitudinal axis and a rectilinear cross-sectional profile transverse to the longitudinal axis of the broach that matches in shape the rectilinear cross-sectional profile of the implant, wherein the rectilinear cross-sectional profile of the broach is larger than the cross-sectional profile of the drill bit.
