Endoscopic Rescue Technique for Iatrogenic Sacroiliac Joint Syndrome Caused by Sextant Percutaneous Pedicle Screw Fixation System.

Abstract

The Sextant percutaneous pedicle screw fixation system is a commonly used technique. In this system, the pedicle screw and the sharp rod are placed through stab incisions. The unique mechanism of action of this system may cause unprecedented adverse effects, such as iatrogenic sacroiliac (SI) joint syndrome. A patient presented with iatrogenic SI joint syndrome caused by the rod of the Sextant system at the L4-L6 level causing ilium irritation and dynamic SI joint instability. The patient was treated with an endoscopy-based technique. This is the first report of endoscopic treatment for iatrogenic SI joint syndrome as an adverse effect resulting from use of the Sextant system. Surgeons need to be aware of iatrogenic SI joint syndrome using the Sextant system when performing percutaneous pedicle screw fixation. An endoscopy-based technique may be an effective alternative to conventional corrective surgery when treating iatrogenic SI joint syndrome using the Sextant system.
