Manufacturer Narrative

According to the available information, the plate was applied anteriorly to the femur after a previous trauma treatment, presumably as a revision.The treatment from anterior leads to an above-average bending load and high deformation of the plate.There is also the question of the type and amount of mobilization as early as 14 days post-op.The check of the available manufacturing documentation (dhr) shows no deviations.The material and fracture analysis could not identify any implant-associated cause of failure.As expected, the fracture was detected at the point of highest stress, the plate-to-screw junction.The present fracture is a common shrinkage fracture with subsequent force fracture of the overloaded residual surface.An inclusion found in the vicinity could be clearly excluded as the cause.Finally, the only possible cause is early mobilization, which led to early overloading (low cycle fatigue) of the plate implant.This is a late report due to a capa action.

Event Description

There was a plate break in a 18 year old male weighing 75 kg who presented a fracture shaft femur and was treated with a pg 4556-11-2 plate.As the patient started early mobilization after 14 days, he presented a plate break and a bone refracture.
