The procedure is usually combined with radiofrequency ablation of the ipsilateral L5 primary dorsal ramus. Though multiple methods have been endorsed to denervate the SI joint, the Simplicity III procedure is a convenient and effective alternative for achieving maximal disruption of nociceptive input from the SI joint. The Simplicity III is a rigid tripolar probe with a sharp-tip that creates an adequate strip lesion that is technically easy to perform. Its pre-curved shape closely approximates the curvature of the sacrum, and it does not require an introducer.
