Manufacturer Narrative

Section: h3, h6: it was reported that, a polarcup trial insert nav 22/55 and a polarcup impactor part for handle were noticed broken.The complaint device, used in treatment, was returned for investigation.The reported issue could be confirmed upon visual inspection, the device was found fractured in two parts.A review of the batch record revealed no deviations from the standard manufacturing process that could have contributed to the reported issue.A review of the complaint history revealed no additional complaint for the batch in question.A review of the risk management documentation verifies the failure mode and severity of the reported issue.Corrective actions has been previously initiated to reduce the occurrence of this issue.The reported batch was produced before the implementation of the corrective action.No further escalation is required.The received instrument is designed to reposition the polarcup shell.It is therefore subjected to repeated impact forces.Additionally, repeated steam sterilization processes could contribute to an embrittlement.It is however unknown for how many cycles this instrument has been used.A functional test simulating 5 years of use was performed.The observed failure could not be reproduced.Based on the conducted investigations the root cause of the fracture could therefore not be determined conclusively.There is no indication that the device failed to match specifications at the time of manufacturing.Nonetheless, in combination with our continuous effort to improve our products, design changes have been implemented to enhance the mechanical behaviour of this device.No further actions are deemed necessary at the time.Smith+nephew will continue to monitor for similar issues.The device will be retained.
