As the plate is implanted, it was not available for inspection.Although the screw did not lock to plate, fracture reduction and the end result of the implantation was satisfactory.Examination of production records of the involved plate did not reveal a deviation that may have contributed to the reported case.Testing of additional plates from the same lot of the involved plate as well as from different production lots indicated that upon application of excessive force, screw spinning may occur at one of the screw holes at plate' proximal portion.As indicated in the ifu for the system, application of high torque during screw tightening should be avoided, as excessive force may damage the bone and/or implant.The report is submitted following an fda inspection at the manufacturer facility.Device is still implanted.
