The reported event that distal lateral femur plate axsos 3 ti for right femur 16 hole / l343mm was alleged of issue s-12 (implant breakage after surgery) could not be confirmed, since the device was not returned for evaluation and no other evidences were provided.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.Some of the possible root causes can be failure to follow the operative technique properly, overloading and early mobilization.The axsos plate system is an internal fixation system which shall fix the broken bone in a correct position until sufficient bone consolidation is achieved.The axsos plating system is not intended to transmit full forces and bending moments of daily routine.Especially in the lower extremity loading and weightbearing have to be individually reduced.Influence factors for the required load reduction are: the type of fracture (e.G.Transverse fracture with sufficient bone support vs.Unstable comminuted fracture w/o sufficient bone contact), the localisation of the fracture (e.G.Diaphysis vs.Metaphysis), the bone quality (e.G.Bone in younger patients vs.Osteoporosis), correct fracture reduction, correct fixation technique (e.G.Correct dimension of the plate, correct positioning of the plate, sufficient lenght of the plate, sufficient bending of the plate, correct screw placement).Depending on these individual influencing factors the attending physician has to determine the maximum loading and has to limit the weight bearing respectively.This is part of the surgeons' education.In the case of an overloading or due to poor implantation technique an implant failure may result.A device inspection was not possible since the affected device was not returned and no other evidences were provided 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.If the device is returned or if any additional information is provided, the investigation will be reassessed.
