Description of Event or Problem

THE PATIENT HAD LEFT SI JOINT ARTHRODESIS IN (B)(6) 2019 WHERE THREE IMPLANTS WERE INSTALLED. THE PATIENT HAD SI JOINT PAIN RELIEF FOR 18 MONTHS BEFORE COMPLAINING OF A RECURRENCE OF SI-JOINT PAIN SYMPTOMS AFTER A HARD FALL. THE SURGEON DETERMINED THAT THE IMPLANTS MAY LOOSENED AFTER THE PATIENT FELL AND DECIDED TO ADD LARGER IMPLANTS TO ACHIEVE A BETTER PRESS-FIT. IN (B)(6) 2021, THE SURGEON PERFORMED A REVISION PROCEDURE WHERE HE REMOVED ALL THREE INITIAL IMPLANTS USING CHISELS AS THEY WERE ALL SOLIDLY FIXED IN BONE. HE THEN INSTALLED LARGER IMPLANTS OF THE SAME TYPE IN EACH OF THE EXPLANT VOIDS. THE PATIENT IS DOING WELL FOLLOWING THE REVISION PROCEDURE.
