Abstract:
1. A method of forming a bore in the ileum, across the sacroiliac joint, and into the sacrum to receive an implant having a rectilinear cross-sectional profile, the method comprising: inserting a guide pin into the ileum, across the sacroiliac joint, and into the sacrum; disposing a drill bit over the guide pin, the drill bit having a longitudinal axis and a cross-sectional profile transverse to the longitudinal axis of the drill bit, the drill bit having a lumen configured to receive the guide pin; drilling a bore along the guide pin with the drill bit, the bore extending from the ileum, across the sacroiliac joint, and into the sacrum; removing the drill bit from the guide pin; disposing a broach over the guide pin, the 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, the broach having a lumen configured to receive the guide pin, wherein the rectilinear cross-sectional profile of the broach is larger than the cross-sectional profile of the drill bit; and shaping the bore with the broach such that the cross-sectional profile of the bore matches the shape of the rectilinear cross-sectional profile of the implant.
