    Description of Event or Problem · 1

    IT WAS REPORTED THAT PATIENT WAS REVISED APPROXIMATELY 3 MONTHS POST-OPERATIVELY DUE TO MIGRATION AND MALALIGNMENT OF THE DUAL MOBILITY LINER. MALALIGNMENT/MIGRATION WERE INITIALLY NOTED ON RADIOGRAPHS TEN DAYS POST-IMPLANTATION. IN INITIAL OPERATIVE NOTES, SURGEON CLEARLY STATES THAT THERE IS A POSSIBILITY OF NEEDING A HEAD/LINER EXCHANGE IN FUTURE IF POSITION OF LINER CHANGES OR SYMPTOMS PRESENT FROM THE HIP. FROM THE REVISION OPERATIVE REPORT: PATIENT HAD SIGNIFICANT TENDINOSIS AND PARTIAL FRAYING. THERE WAS SIGNIFICANT METALLOSIS IN THE HIP JOINT FROM DISPLACEMENT OF METAL LINER FROM THE CUP. DUAL MOBILITY HEAD WAS REMOVED. TRUNNION WAS NOTED TO BE MILDLY SCRATCHED WITH STEM WELL FIXED. ONE OF THE SCREWS WAS PROMINENT IN THE SHELL AND WAS MOST LIKELY WAS THE REASON FOR DISPLACEMENT OF THE LINER, ACCORDING TO SURGEON. THIS SCREW WAS REMOVED.
