    Additional Manufacturer Narrative · 1

    THIS DEVICE IS USED FOR TREATMENT, NOT DIAGNOSIS. THE RELEVANT DIMENSIONS OF THE DAMAGED HEXAGON CAN NOT BE VERIFIED ANYMORE. HOWEVER, THE APPEARANCE TO THE COMPLETE HALF RING INDICATES THAT THIS WAS AN OFTEN AND INTENSE USED DEVICE. BASED ON THAT WE SUPPOSE THAT THE DAMAGE AT THE FIXATION WAS CAUSED BY NUMEROUS OVER-TIGHTENS OF THE FIXATION SCREW OVER THE YEARS. THIS PART IS HALF OF A SYNFRAME HOLDING RING. THIS PART IS IN GOOD CONDITION AND COMPLETELY FUNCTIONAL.
