Manufacturer Narrative

Product complaint # (b)(4).Investigation summary: the investigation identified the device was broken.The complaint shall be closed with a justified conclusion; it will be entered into the complaint database and monitored through trend analysis.The complaint sample consisted of (1) 254401006 attune femoral impactor, lot number au3922447.Visual examination of the product confirmed the device was broken into two pieces.The lot number au3922447 indicates that this device is from an annealed batch of impactors.Complaints databases searched on product code 254401006 identified previous complaints received for this failure mode.Expert opinion (refer dve-002822-dvr) indicates that this failure mode is associated with environmental stress cracking (esc).The lot au3922447 of the attune femoral impactor is an annealed lot.While annealing helps in reducing the internal stress in the molded part, a complete reduction in internal stresses of the device is not achievable.There is a wide range of cleaning agents used across hospitals and it is possible that some result in greater degradation in the robustness of the device from repeated exposure.A pra (dva-107261-pra) held in (b)(6) 2012 when a similar device (attune fb impactor- 254401003) either cracked or broke into large pieces did not identify a potential patient harm based on the nature of the failure.Post pra evaluation (held in september 2012); a new additional failure observation was made and showed that in some instances the attune impactors fractured (either completely or partially) and resulted in small fragments.This issue led to qrb (qrb-(b)(4)) initiation on october 2014 and recommended a field correction in the form of a communication to device users for all 3 attune impactors- rp, fb & fem.The field safety notice stresses to ensure that no instruments or pieces of instruments are left in the surgical site prior to closure.There was no recommended field action other than this communication.Full lavage of the joint-space is recommended before and after implantation.Ifu 0902-00-836 contains wording relating to the importance of removing fragments from the surgical site.Both failure modes; patient harm & delay to surgery have been adequately covered in the risk assessment of the device and no further updates are required.The dfmea scores reflect the current failure rates of the device.However, in order to investigate the root cause and possibility of reducing this occurrence, (b)(4) has been initiated and can be referenced for further details.If information is obtained that was not available for the initial medwatch, a follow-up medwatch will be filed as appropriate.
