Manufacturer Narrative

A product investigation was completed: the investigation of the returned dhs/dcs screw has shown that the positioning groove of the screw is damaged due to an inadequate handling.A functional test with an available plate has shown that the screw could not be inserted into the plate.It is likely that the connection between the wrench and the screw was not aligned as intended and therefore this occurrence in combination with a mechanical overload situation led to the deformation of the screw.The surgical technique guide give guidance to prevent such occurrence and to ensure a correct load transfer it is crucial to have an appropriate connection between the dhs-screw and the connecting screw 338.310, which is guided through the wrench 338.300.The device history record was researched, no abnormal findings were identified.There were no issues during the manufacturing of the product that would contribute to this complaint condition.No product fault could be detected.On previous follow up report, date was reported as april 04, 2017, but should have been march 30, 2017.Device was used for treatment, not diagnosis.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
