Manufacturer Narrative

It was reported that, during thr, a polarcup shell ti-plasma/ha 53 non-cem and polarcup shell ti-plasma/ha 55 non-cem, when opened, one of the two protective caps for the insertion of the pegs has not being unscrewed, making it impossible to use.Both devices, intended for use in treatment, have not been returned for investigation.An evaluation of the complained devices could therefore not be conducted and the reported failure mode could not independently be confirmed.A review of the complaint history revealed no other complaint being reported for the batch in question.A review of the batch record revealed no deviations from the standard manufacturing process that could have contributed to the reported failure mode.The surgical technique (lit no.01620-en (1582) v7 10/20) describes the correct removal of the polarcup plugs using the unidirectional t handle (75023347): "release the plugs by turning the t wrench in the direction indicated on the plug cover." based on the performed investigations, the reported failure mode could not be confirmed.A relationship between the reported event and the devices cannot be confirmed.There is no indication that the reported devices failed to meet manufacturing specifications upon release for distribution.A worn t-handle is known to contribute to the reported event.According to document "processing (cleaning, disinfection and sterilization) of instruments from smith & nephew orthopaedics ag" (lit.N°03389-en 1363 v3 11/19), all devices must be inspected and controlled for proper functioning after cleaning/disinfection.Based on available information the root cause for the reported jamming cannot clearly be identified and stays undetermined.Based on the conducted investigation the need for corrective action is not indicated.Nevertheless, smith + nephew will continue to monitor both devices for similar issues.The complaint will be reopened should additional information or one of the devices be received.
