Correction to d2a common device name and d2b product code.An event regarding adverse local tissue reaction(altr) and fretting involving an lfit v40 cocr head that was mated with a restoration stem was reported.The cocr head has been identified to be within scope of nc and capa.The events were confirmed.Method & results: device evaluation and results: visual inspection of the provided photographs indicated a recently explanted device.The trunnion of the stem was worn and the stem was fractured.As this was not reported, it most likely occurred during the explantation of the device.Material analysis, functional and dimensional inspections could not be performed as the device was not returned.Clinician review: a review of the provided medical records by a clinical consultant stated the following comment: this patient underwent a total hip arthroplasty in 2008 according to the product inquiry.Now the patient is experiencing pain with elevated cobalt and chromium levels requiring revision surgery.I actually have no definitive documentation of this patient's hip replacement since i have no office records, operation reports or x-rays.I can confirm that he has elevated cobalt and chromium levels which would be of concern for failure of the implant due to possible trunnionosis.In addition the patient was told that the femoral head was not angled correctly and that he would require revision surgery.Regarding the possibility of a recall stryker would have to check to see if this femoral head was indeed part of a recall.Regarding the root cause of this event, it is multifactorial and i cannot determine it with certainty.It can be contributed to by surgical technique, patient activity level and bmi and implant factors.Elevated cobalt and chromium levels with "clacking" and pain in the hip can be indicative of trunnionosis with femoral head/trunnion failure.Device history review: a review of the device history records could not be performed as lot code information was unknown.Complaint history review: a complaint history review could not be performed as lot code information was unknown.Conclusions: the investigation concluded through a review of the provided medical documents, that 'elevated cobalt and chromium levels with "clacking" and pain in the hip can be indicative of trunnionosis with femoral head/trunnion failure.' as no lot details were supplied then its not possible to determine if the patient¿s restoration stem implant is subject to a recall.The associated metal head was determined to be part of a recall.No further investigation is required at this time.If additional information becomes available to indicate further evaluation is warranted, this record will be reopened.
