A review of the raw material device history record revealed this lot met all specifications with no non-conformance noted. This raw material lot met all dimensional and visual criteria at the time of manufacture with no issues documented during the manufacture that would contribute to this complaint condition. H3, h6: customer quality conducted a review of the provided x-rays. One tfna helical blade (part 04. 038. 110s | lot 7920234) was reported with the complaint category of ¿functional: migration/backout/pull-out : rm. ¿ a visual inspection via the provided x-rays and pictures, drawing review, complaint history review, and risk assessment review were performed as part of this investigation.

The investigation is based on the reported information and provided x-rays. Device condition: the provide picture shows the proximal end of a tfna head element. Due to the resolution, minimal detail can be gathered, however, no product issues were observed in the image. The provided x-rays do not show the distal tip of the tfna helical blade which was reported to have cut out or the nail/blade junction. Thus, the complaint condition could not be confirmed. Replication of the condition is not applicable for this complaint condition. Lot number review: date of manufacture: 19march2015 a review of the device history record and the raw material device history record revealed this lot met all specifications and the lot went through the required steps during the inspection at the time of manufacturing and the dhr records showed no issues concerning the material or material conditioning. Drawing review: based on the date of manufacture the following drawings, reflecting the current and manufactured revision, were reviewed. Ti tfna helical blade: during the investigation no product design issues were observed that may have contributed to the complaint condition. As the physical device was not received no further dimensional or material testing could be completed. Risk assessment review: the trochanteric fixation nail - advanced (tfna) design and clinical risk management (dcrm) document, was reviewed and found to adequately address the complaint condition. Root cause: no definitive root cause was able to be determined as circumstances surrounding the event are unknown. It was reported that the user suspected they forgot to engage the locking mechanism during the initial surgery which would impact the complaint condition of migration. However, as the device was not returned a root cause could not be determined. No design of manufacturing issue was identified. Based on the investigation findings, it has been determined that no corrective and/or preventative action is proposed. 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.
