Abstract

A surgical system for preparing the sacroiliac (SI) joint for a fusion, comprising a sliding joint finder and a working cannula. The working cannula comprises a body having a central axis that runs the length of the body. The body of the working cannula comprises a distal end, a proximal end and a central cavity that is positioned along the central axis of the working cannula and has suitable dimensions for sliding the working cannula over the sliding joint finder and the working cannula further comprises two protrusions extending proximally. In addition, the two protrusions have uneven lengths such that when the working cannula is inserted, the longer of the two protrusions engages the SI joint at a superior end of the SI joint and the shorter of the two protrusions engages the SI joint at an inferior end of the SI joint.
