    THE REPORTED EVENT COULD BE CONFIRMED, FROM THE PROVIDED X-RAYS FOR EVALUATION AND MATCHES THE ALLEGED FAILURE MODE. THE DEVICE INSPECTION WAS NOT POSSIBLE AS THE PRODUCT WAS NOT RETURNED FOR INVESTIGATION. THE DEVICE HISTORY RECORD COULD NOT BE REVIEWED BECAUSE THE AFFECTED DEVICE WAS NOT RETURNED, AND THE LOT NUMBER WAS NOT COMMUNICATED. A REVIEW OF THE LABELING DID NOT INDICATE ANY ABNORMALITIES. A FEW X-RAYS WERE PROVIDED WHICH WERE PRESENTED TO OUR HEALTH CARE PROFESSIONAL FOR EVALUATION, AND A QUESTION ABOUT THE MOST LIKELY REASON FOR THIS EVENT WAS ASKED, TO WHICH THE MEDICAL EXPERT REPLIED: ¿THERE IS VERY LIMITED INFORMATION FOR ME TO WORK WITH HERE. NON-UNION IS CONFIRMED FOR THIS CASE IN THE ATTACHED X-RAY SHOTS. AS YOU MAY BE AWARE, NON-UNION IS OFTEN MULTI-FACTORIAL. ONE OF THE FACTORS IN THIS CASE MAY HAVE BEEN INSTABILITY OF THE CONSTRUCT FOR THIS LOW FEMUR FRACTURE. THE CONTINUOUS MOVEMENT IN THE NAIL, MIGHT HAVE CAUSED THE NON-UNION AND BREAKAGE OF THE SCREW.¿ [ORIGINAL STATEMENT(S)] MORE DETAILED INFORMATION ABOUT THE COMPLAINT EVENT AS WELL AS THE AFFECTED DEVICE MUST BE AVAILABLE IN ORDER TO DETERMINE THE ROOT CAUSE OF THE COMPLAINT EVENT.
