Reported event: an event regarding disassociation & wear involving a metal head was reported.The event was not confirmed.Method & results -product evaluation and results: material analysis, visual, functional and dimensional inspections could not be performed as the device was not returned.-medical records received and evaluation: a review of the provided medical records by a clinical consultant indicated: "a patient underwent a primary total hip arthroplasty for right hip arthritis.The procedure was routine per the operative report.Pre and postoperative medical information and radiographs were not provided for review.No data on the ensuing history were provided for review prior to a revision hip arthroplasty.The patient apparently had a nontraumatic pop and subsequent fall, the date was not defined, but he presented on 05/17/2024.He underwent revision surgery on 05/24/2024.At the time of surgery, metallosis was described as well as disassociation of the femoral head from the trunnion, and severe trunnion damage.The trunnion was described as "broken".A new liner was placed, an mdm, and a new competitive femoral stem placed.The postoperative results, medical history, and radiographs were not provided for review.Event confirmation: a primary right hip arthroplasty with stryker components can be confirmed.A revision hip arthroplasty can be confirmed.The surgeon¿s dictated findings were of a "broken trunnion" and intraoperative findings were consistent with metallosis and disassociation of the femoral head from the trunnion.Radiographs or pathologic specimen examination were not provided for confirmation of the surgeon's findings.Root cause: the root cause of the primary hip arthroplasty was hip arthritis.The root cause of the revision surgery appeared to be disassociation of the femoral head from a severely worn trunnion." -product history review: review of the device history records indicate devices were manufactured and accepted into final stock with no relevant reported discrepancies.-complaint history review: there have been no other similar events for the lot referenced.Conclusions: it was reported that the patient was revised due to disassociation of the head from the stem.A review of the provided medical records by a clinical consultant indicated: "a patient underwent a primary total hip arthroplasty for right hip arthritis.The procedure was routine per the operative report.Pre and postoperative medical information and radiographs were not provided for review.No data on the ensuing history were provided for review prior to a revision hip arthroplasty.The patient apparently had a nontraumatic pop and subsequent fall, the date was not defined, but he presented on 05/17/2024.He underwent revision surgery on 05/24/2024.At the time of surgery, metallosis was described as well as disassociation of the femoral head from the trunnion, and severe trunnion damage.The trunnion was described as "broken".A new liner was placed, an mdm, and a new competitive femoral stem placed.The postoperative results, medical history, and radiographs were not provided for review.Event confirmation: a primary right hip arthroplasty with stryker components can be confirmed.A revision hip arthroplasty can be confirmed.The surgeon¿s dictated findings were of a "broken trunnion" and intraoperative findings were consistent with metallosis and disassociation of the femoral head from the trunnion.Radiographs or pathologic specimen examination were not provided for confirmation of the surgeon's findings.Root cause: the root cause of the primary hip arthroplasty was hip arthritis.The root cause of the revision surgery appeared to be disassociation of the femoral head from a severely worn trunnion." the subject device has been identified to be within scope of nc and capa.Lot specific voluntary recall pfa 1757583 was initiated for the lfit v40 cocr heads within scope of nc and capa.The investigation revealed that only specific catalog numbers and specific lots are impacted by the regulatory action and that the affected lots were manufactured on or before march 4, 2011.The root cause analyses identified a process related anomaly as to the affected sizes and lots.The affected product has all been implanted and/or expired.No further investigation is required.
