Additional Manufacturer Narrative
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, h6: part #: 388.394, synthes lot number: u234826, supplier lot number: u234826, release to warehouse date: december 24, 2015, supplier: (b)(4), the raw material was confirmed to be correct per the specification with no (relevant) non-conformance noted.Review of the device history record(s) showed that there were no issues during the manufacture of this product, and any sub-components, which would contribute to this complaint condition.Visual inspection: the evaluation of the received drill bit has shown that a piece of about 13mm length is broken off.The tip and as well the cutting edges show signs of use.Otherwise is the drill bit in good condition.Dimensional inspection: checked dimensions with caliper 3-01-19788.Outer diameter specification 2.4mm 0/-0.05 / measured: 2.37mm = pass.Core diameter at the breakage specification 0.4mm +/-0.05 / measured: 0.44mm = pass.Overall length (measured with a ruler to define length of missing piece) specification 205mm +/-1 / measured: 192mm = damaged post-manufacturing.Drawing/specification review: the drawing was reviewed during the evaluation to verify the measurements, the material and the hardness.The review of the manufacturing documents has shown that with 440a stainless steel the correct material was used and that the hardness was with 50.5 hrc within the specification of 50-55 hrc.Summary: the received condition of the device is concordant with the complaint description and the complaint condition is confirmed.Based on the provided information we are not able to determine the exact cause of this complaint.We only can assume that a mechanical overloading situation, for example metallic contact or lateral stress, has caused the breakage.Please also note; blunt drill bits require more mechanical power during the application, therefore we would like to draw your attention on page 4 in the leaflet ¿important information¿.Check instruments for sound surfaces, and correct adjustment and function.Do not use severely damaged instruments, instruments with unrecognizable markings, corrosion, or blunt cutting surfaces.We conclude that the cause of failure is not due to any manufacturing non-conformances.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.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.
