摘要：
An undercutting system for preparing a region between ilium and sacrum for sacroiliac fusion. The undercutting system includes an insertion apparatus and a cutting assembly. The insertion apparatus has an elongate shaft and a rotatable handle. The cutting assembly is operably attached to the insertion apparatus. Rotation of the handle with respect to the shaft causes the cutting assembly to move with respect to the shaft between a retracted configuration and an extended configuration. When in the extended configuration, at least a portion of the cutting assembly extends laterally from the shaft.
