Manufacturer Narrative
Patient ethnicity is unknown. Part: 04. 027. 052s; lot: l745600; manufacturing site: (b)(4); release to warehouse date: january 29, 2018, expiry date: january 01, 2028; the device history record shows this lot of (b)(4) pieces was processed through the normal manufacturing and inspection operations with no rework or nonconformities noted. This lot met all dimensional, visual and functional criteria at the time of release with no issues documented during the manufacturing process. Review of the device history record showed that there were no issues during the manufacture of this product which would contribute to this complaint condition. Investigation site: (b)(6); selected flow(s): 2. Device interaction/functional visual inspection: the blade is completely blocked with the extraction screw. It is impossible to disassemble the blade from the screw. The tip of the blade is badly deformed and shows strong signs of contact with the nail during insertion. This is clear indication that the blade got damaged during insertion. This may happen when the blade is not correctly aligned with the nail. The blade in question is in complete unlocked position and can be turned freely. The locking mechanism is damaged and is not able to be locked / unlocked. The system is completely destructed. Functional test: as result of the damages, no functional test is possible. The mechanism of locking / unlocking is destructed and the blade is not possible to release from the extraction screw. As the blade is in unlocked position, the complaint is classified as confirmed. It is not possible to lock the system as complained. As result to the damages and as the blade is blocked on the screw, no dimensional- or functional tests are possible. Design and clinical risk management (dcrm) was reviewed and found to adequately address the harm of this complaint condition. The complaint is adequately addressed by the risk assessment. As result of our investigations, use error while insertion is most probably root cause the reported problem. 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.
