Manufacturer Narrative

An event regarding pain involving a triathlon insert component was reported.The event was not confirmed.Method & results: -device evaluation and results: not performed as product was not returned.-medical records received and evaluation: insufficient medical records were received for review.-device history review: review of the dhr was satisfactory.-complaint history review: review of the chr confirmed that there were no other similar events for the lot.Conclusions: clinician review of the available medical records indicated: regarding the 2016 complaints, there is a bone scan from 2015, that was "hot" but such findings are difficult to interpret if no context with other information is available.There is one radiological report that speaks about a small radiolucent line but also this is not complete and therefore it is not certain the baseplate was loose.Even if loose, the cause would be unclear because no other info is available to answer that question.X-rays are missing while also the records do not give any info as to what might have caused the problem and therefore this case can unfortunately not be solved with the available information.No further investigation is possible with the information received.Further information such as product evaluation, patient history, medical records, operative notes and x-rays are needed to complete the investigation for determining a root cause.A capa trend analysis was conducted for the reported failure mode and concluded pain may result from other factors not necessarily related to the device.No further investigation is possible at this time.If additional information becomes available to indicate further evaluation is warranted, this record will be reopened.
