Abstract
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.
Claims21
A method of forming a bore in the ileum, across the sacroiliac joint, and into the sacrum to receive an implant having a cross-sectional profile defined by a plurality of apices, 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 cross-sectional profile transverse to the longitudinal axis of the broach that is defined by a plurality of apices and that matches in shape the cross-sectional profile of the implant, the broach having a lumen configured to receive the guide pin, wherein the 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 cross-sectional profile of the implant.
A method of forming a bore in the ileum, across the sacroiliac joint, and into the sacrum to receive an implant having a cross-sectional profile defined by a plurality of apices, the method comprising:
- drilling a bore through the ileum, across the sacroiliac joint, and into the sacrum with a drill bit, the drill bit having a longitudinal axis and a cross-sectional profile transverse to the longitudinal axis of the drill bit;
- and
- shaping the bore with a broach such that the cross-sectional profile of the bore matches the shape of the cross-sectional profile of the implant, the broach having longitudinal axis and a cross-sectional profile transverse to the longitudinal axis of the broach that is defined by a plurality of apices and that matches in shape the cross-sectional profile of the implant, wherein the cross-sectional profile of the broach is larger than the cross-sectional profile of the drill bit.
A method of forming a bore in the ileum, across the sacroiliac joint, and into the sacrum to receive an implant having a cross-sectional profile defined by a plurality of apices, the method comprising:
- inserting a guide pin into the ileum, across the sacroiliac joint, and into the sacrum;
- disposing a soft tissue protector over the guide pin;
- disposing a drill bit through the soft tissue protector and 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 cross-sectional profile transverse to the longitudinal axis of the broach that is defined by a plurality of apices and that matches in shape the cross-sectional profile of the implant, the broach having a lumen configured to receive the guide pin, wherein the 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 cross-sectional profile of the implant.
