Arthrodesis Using Bilateral Dual Iliac Screws With Autologous Iliac Bone Transfer for the Treatment of Pyogenic Sacroiliitis

Abstract

Pyogenic sacroiliitis is a relatively rare condition that often leads to surgical treatment, including debridement and arthrodesis. Here we introduce a new surgical technique using bilateral dual iliac screws to secure early ambulation and maximal fusion success rate for the treatment of pyogenic sacroiliitis. We retrospectively reported a case and technical reports of pyogenic sacroiliitis treated by a new bilateral dual iliac screw fixation arthrodesis technique using radiologic outcomes, including plain X-rays and MRI scans, as well as outcomes based on the visual analogue scale for pain measurement. This technique improved uncontrolled pyogenic sacroiliitis with immediate stability that enabled ambulation and secured firm fixation for extensive evacuation of infected debris and subsequent autograft bone arthrodesis. In conclusion, we recommend bilateral dual iliac screw fixation for the treatment of pyogenic sacroiliitis, as this technique can improve uncontrolled pyogenic sacroiliitis with immediate stability.
