Manufacturer Narrative

Product complaint # (b)(4).Depuy synthes is submitting this report pursuant to the provisions of 21 cfr, part 803.This report may be based on information which depuy synthes has not been able to investigate or verify prior to the required reporting date.This report does not reflect a conclusion by fda, depuy synthes or its employees that the report constitutes an admission that the device, depuy synthes, or its employees caused or contributed to the potential event described in this report.H3, h4, h6: device history lot part number: 03.505.004, lot number: 8125270, manufacturing site: selzach, supplier: (b)(4), release to warehouse date: 08.Mar.2013.A manufacturing record evaluation was performed for the finished device lot number, and no non-conformances were identified.H3, h6: investigation summary: investigation site: cq zuchwil.Selected flow: device interaction/functional.Visual inspection: the received handle for screwdriver is in a very used condition, there are wear and stress marks all over.The thread flanks at the forefront are worn.The anodized layer is worn away at all damages which indicates that the were caused post-manufacturing by intense use.Functional testing: the functional test has shown that the torque is not transferred from the turning handle (03.505.005) to the coupling piece at the forefront of the handle.The coupling piece at the forefront does turn freely on the drive shaft of the handle.The malfunction is not related to the turning handle as the issue can be replicated when the drive shaft is turned with a standard screwdriver in stead of the turning handle.Dimensional inspection: the relevant dimensions cannot be verified as the shaft cannot be disassembled from the handle due to the press fit.Document/specification review: drawing was reviewed.The review has shown that the coupling piece at the forefront is fixated with a 1mm pin on the drive shaft.The current revision c of this drawing is in place since april 2006 which speaks against a design related issue.Investigation conclusion: the complaint is confirmed for the handle, the device is not functional as required as the coupling at the forefront is not fixed on the drive shaft anymore, thus the load is not transferred as required.Based on the age and the used condition of the device a manufacturing related issue can be excluded.The exact cause of this occurrence cannot be defined, it can only be assumed that the pin which holds the coupling in position on the drive shaft was sheared off by a mechanical overload during use and that therefore the coupling turns freely on the shaft.Based on the investigation findings, it has been determined that no corrective and/or preventative action is proposed as no product related issue could be detected.Additional monitoring for any potential safety signals will be conducted through complaint trending and other post market safety surveillance activities.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.
