Percutaneous sacroiliac joint arthrodesis: a novel technique

Abstract

Study design: Consecutive case series.

Objective: To report a new percutaneous sacroiliac joint (SIJ) arthrodesis technique utilizing a Hollow Modular Anchorage screw.

Summary of background data: A variety of SIJ arthrodesis techniques have been reported in the established academia to treat intractable SIJ pain. None combines minimal surgical exposure, instrumented fixation, and bone grating.

Methods: We describe a new percutaneous SIJ arthrodesis technique for patients with intractable SIJ pain. Preoperative and postoperative Oswestry Disability Index (ODI), Visual Analog Scale (VAS) for pain, and postoperative subjective patients' satisfaction were assessed for all patients. Minimum 2 years follow-up is documented.

Results: Nine patients underwent SIJ arthrodesis with the new technique. The mean ODI value dropped from 59 (range: 34 to 70) preoperatively to 45 (range: 28 to 60) postoperatively (P<or=0.005). The mean VAS value dropped from 8.1 (range: 7 to 9) preoperatively to 4.6 (range: 3 to 7) postoperatively (P<or=0.002). The mean patients' satisfaction was 6.8 (range: 5 to 8).

Conclusions: The new technique may offer a safe and effective treatment for intractable SIJ pain.
