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.H11 additional narrative: h3, h6: the product was returned to j&j medtech orthopaedics for evaluation.Visual inspection of the returned device found plate was broken, remnant was returned for revision.The broken fragment was returned for examination and the fracture surface was examined; the center section of the fracture suggest that the implant was exposed to high stress.Other section of the fracture shows a pattern of a progressive small cycle of fatigue.Therefore, based on this evidence it is reasonable to conclude that the fracture was caused in two events the first were the implant underwent a high stress and started cracking, and the second event were a low fatigue cycle cause the edges of the plate to broke as a consequence of the damage caused in the first event.There is no indication of damage related to material issues was observed.Additionally, it was observed with signs of scratches and wear which could have been due to implantation and extraction process as stated on the va lcp ankle trauma system 2.7/3.5 surgical technique guide, se_834596 rev.Ad.As with all major surgical procedures, risks, side effects and adverse events can occur.While many possible reactions may occur, some of the most common include: problems resulting from anesthesia and patient positioning (e.G.Nausea, vomiting, dental injuries, neurological impairments, etc.), thrombosis, embolism, infection, excessive bleeding, iatrogenic neural and vascular injury, damage to soft tissues incl.Swelling, abnormal scar formation, functional impairment of the musculoskeletal system, sudeck¿s disease, allergy/hypersensitivity reactions, and side effects associated with hardware prominence, malunion, non-union.With the information provided is not possible to determine a potential cause at this moment.The mode of failure of the device is multi-factorial and consideration must be given to all other potential influences such as surgical process, patient variables (e.G.Activity level and use), anatomical considerations and patient changes over time.Any conclusions from the investigational input provided have to be placed into context with all other relevant factors a dimensional inspection was unable to be performed due to the post-manufacturing damage.A functional test was not performed since it was not applicable to the complaint condition.The overall complaint was confirmed as the observed condition of the 2.7/3.5 va antlat dstl tib pl/12 h/lft would have contributed to the complained device issue.Based on the investigation findings, it has been determined that no corrective and/or preventative action is proposed.There is no indication that a design or manufacturing issue has caused the reported complaint condition.As part of depuy synthes quality process, all devices are manufactured, inspected, and released to approved specifications.Additional monitoring for any potential safety signals will be conducted through complaint trending and other post-market safety surveillance activities.Device history review: a dhr review was not performed for this lot 21p7179.This lot number 21p7179 was manufactured by elmira.Please reassign this task to the correct group.Part number: 02.118.211-us.Lot number: 21p7179.Part manufacture date: 25-oct-2019.Manufacturing location: elmira.Part expiration date: n/a.Nonconformance noted: n/a.Dhr record review: a review of the device history record revealed no complaint related anomalies.The device history record shows this lot of 2.7/3.5mm va-lcp anterolateral distal tibia pl/12 holes left was processed through the normal manufacturing and inspection operations in elmira with no rework nor nonconformities noted.This lot met all dimensional, visual, and packaging criteria at the time of release from elmira with no issues documented during the manufacture that would contribute to this complaint condition.A review of the raw material device history record revealed this lot met all specifications with no nonconformance 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.A dhr review was not performed for this lot 21p7179.This lot number 21p7179 was manufactured by elmira.Please reassign this task to the correct group.This lot met all dimensional, visual, and packaging criteria at the time of release with no issues documented during the manufacture that would contribute to this complaint condition.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
