Abstract

A system for preparing the sacroiliac (SI) joint for an SI joint fusion, and optionally delivering an implant to the SI joint, is described herein. The implant is inserted via an inferior inlet approach. A sliding joint finder is inserted into the joint, followed by insertion of a working cannula. The working cannula is operatively coupled to the sliding joint finder, in that it is configured to fit over the sliding joint finder, allowing subsequent removal of the sliding joint finder, and providing a hollow cavity for joint fusion preparation, decortication and insertion of an implant. This system and method provides a less invasive and safer approach for fixing an SI joint or delivering an implant to the SI joint than currently available methods.

Description

CROSS-REFERENCE TO RELATED APPLICATION

[0001] The present application claims priority to U.S. Provisional Application No. 62 / 151,842, filed on Apr. 23, 2015, by Michael Black, Kenan Aksu, and Damian Heinz, the disclosure of which is incorporated herein by reference in its entirety.FIELD OF THE INVENTION

[0002] The present invention relates generally to surgical procedures for a sacroiliac (SI) joint, and more specifically, to systems for guiding and delivering SI joint implants in place.BACKGROUND OF THE INVENTION

[0003] Sacroiliac (SI) joints are located between the sacrum and the right and the left iliac bones, respectively. The sacrum is a triangular bone in the lower back formed from fused vertebrae and situated between the two hipbones of the pelvis. The ilium is the largest and uppermost bone of the pelvis.

[0004] The SI joints provide support for the entire weight of the upper body when a human stands erect, which creates a large amount of stress on the SI joints. Therefore, these jo...
