Manufacturer Narrative

The reported event could be confirmed with the help of report of medical-legal technical consultancy provided for investigation.The device inspection was not possible as the product was not returned for investigation.A review of the device history for the reported lot did not indicate any abnormalities.No corrective actions are required at this time.No indications of material, manufacturing or design related problems were found during the investigation.A review of the labeling did not indicate any abnormalities.The instructions for use instructs user that: ¿the following are the most frequent adverse effects involving the use of internal fracture fixation devices: delayed union or non-union of the fracture site.These devices can break when subjected to the increased loading associated with delayed unions and/or non-unions.Internal fixation devices are load sharing devices which are intended to hold fractured bone surfaces in apposition to facilitate healing.If healing is delayed or does not occur, the appliance may eventually break due to metal fatigue.Loads on the device produced by load bearing and the patient¿s activity level will dictate the longevity of the device.Conditions attributable to non-union, osteoporosis, osteomalacia, diabetes, inhibited revascularization and poor bone formation can cause loosening, bending, cracking, fracture of the device or premature loss of rigid fixation with the bone.¿ formal medical opinion was sought from an experienced independent medical expert as below; "this can really not be assessed with the x-rays.There is a dislocated subtrochanteric fracture described, which is typically associated with a high amount of failure.Besides the x-rays i did not find any further information on additional disease, age and bmi of the patient or on postoperative recommendations regarding weight bearing.These informations would be necessary for a sound assessment of the case." 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.However, one of the possible root causes of the nail breakage is patient related i.E.Delayed consolidation/healing.If device is returned or any further information is provided, the investigation report will be reassessed.
