    CORRECTED FIELDS: H6 (DEVICE CODE GRID AND HEALTH IMPACT CODE GRID). THE REPORTED EVENT COULD BE CONFIRMED. THE DEVICE WAS NOT RETURNED BUT EVIDENCE WAS PROVIDED, BASED ON PROVIDED INFORMATION WHICH MATCH THE ALLEGED FAILURE. A DEVICE INSPECTION WAS NOT POSSIBLE SINCE THE AFFECTED DEVICE WAS NOT RETURNED FOR INVESTIGATION. THE COMPLAINT EVENT DESCRIPTION STATED THAT THE HUMERAL SIDE WAS NOT ENOUGH CUT DURING SURGERY AND THE PATIENT HAD PAIN. FROM THIS INFORMATION PROVIDED, THE OPINION OF THE MEDICAL EXPERT WAS REQUESTED ON THIS CASE AND STATED AS FOLLOWS: IT IS KNOWN HOWEVER THAT A NON-ANATOMICAL RECONSTRUCTION OF THE SHOULDER IN SHOULDER HEMIARTHROPLASTY MAY LEAD TO EARLIER FAILURE BECAUSE OF ROTATOR CUFF DAMAGE. TOO MUCH TENSION ON THE ROTATOR CUFF IS NOT ONLY PAINFUL BUT ALSO KNOWN TO BE ASSOCIATED WITH EARLIER ROTATOR CUFF FAILURE (...). CONCLUSION: NONANATOMIC RECONSTRUCTION OF THE PROXIMAL HUMERUS IN HEMIARTHROPLASTY IS ASSOCIATED WITH LOWER FUNCTIONAL OUTCOMES, AS WELL AS HIGHER RISKS OF COMPLICATIONS AND REVISION. NON-ANATOMICAL RECONSTRUCTION IS A USER-RELATED ISSUE, HOWEVER, MAKES THE STEM AND HUMERAL HEAD PART OF THE EVENT. BASED ON INVESTIGATION, THE ROOT CAUSE WAS ATTRIBUTED TO A USER RELATED ISSUE. THE FAILURE WAS CAUSED BY A NON-ANATOMICAL RECONSTRUCTION OF THE PROXIMAL HUMERUS IN SHOULDER HEMIARTHROPLASTY. A REVIEW OF THE DEVICE HISTORY WAS NOT POSSIBLE BECAUSE THE LOT NUMBER WAS NOT COMMUNICATED. NO CORRECTIVE ACTIONS ARE REQUIRED AT THIS TIME. A REVIEW OF THE LABELING DID NOT INDICATE ANY ABNORMALITIES. INDICATIONS OF MATERIAL, MANUFACTURING, OR DESIGN RELATED PROBLEMS WERE UNABLE TO BE IDENTIFIED AS THE CATALOG NUMBER AND LOT NUMBER WERE NOT COMMUNICATED. IF ANY ADDITIONAL INFORMATION IS PROVIDED, THE INVESTIGATION WILL BE REASSESSED.
