    THE EVENT OCCURRED DURING THE THA (RIGHT) PROCEDURE. AT THE TIME OF PRE-OPERATIVE SETTING, THE ANGLE OF THE OFFSET REAMER WAS SET TO 45° TO THE RIGHT ACCORDING TO THE MANUAL, BUT WHEN THE REAMER WAS PUT INTO THE WOUND, THE OFFSET DID NOT MATCH AND WAS CHANGED BY THE SURGEON HIMSELF. WHEN THE MSP CHECKED THE ANGLE WITH THE SURGEON, THE SURGEON RESPONSE WAS 90°, SO THE ANGLE WAS CHANGED TO 90°. AFTER THAT, HE WAS RELUCTANT TO REAM, BUT JUDGED THAT THE REAMER WAS BEING FLIPPED BECAUSE THE CENTER DID NOT FIT AND HE CONTINUED TO REAM. AFTER REAMING, THE POSITION WAS VISUALLY INSPECTED AND IT WAS POINTED OUT THAT THE CUTTING POSITION WAS INCORRECT, AND IT WAS SUSPECTED THAT THE PELVIC ARRAY HAD MOVED, AND THE REGISTRATION ACCURACY WAS CONFIRMED ON THE CT VIEW. WHEN THE INSIDE OF THE ACETABULUM WAS CHECKED WITH A POINTER, THERE WAS NO PROBLEM IN THE POSITION, BUT IT SEEMS THAT THERE WAS A DEVIATION IN THE DEPTH, AND ALTHOUGH THE UPPER ANTERIOR ILIAC SPINES ON BOTH SIDES WERE CONFIRMED, THERE WAS NO DEVIATION AND THERE WAS A PROBLEM WITH REGISTRATION ACCURACY. NEXT, WHEN THE REPORTING SR SUSPICIOUSLY CONFIRMED THAT THE ANGLE OF THE OFFSET HANDLE WAS SET INCORRECTLY, THE ANGLE ON THE REAMER
