Manufacturer Narrative

Reported event: an event regarding dislocation involving a uhr head was reported.The event was confirmed via clinician review.Method & results: -product evaluation and results: the bipolar head and metal head were returned for evaluation.Damage is consistent with attempted assembly/implantation.There was nothing remarkable to notice.Dimensional & functional inspections: not performed as the device was returned damaged.Damage is consistent with attempted assembly/implantation.Due to damage sustained from the assembly/ implantation attempts, any results received from a dimensional/functional inspection would not be reflective of the manufactured state of the device.-clinician review: a review of the provided medical information by a clinical consultant indicated: the x-ray provided demonstrates the dissociation of the bipolar head from the femoral head of the cemented stem confirming this event.The limited information provided precludes the assignment of a root cause for this event.-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 dislocation between femoral head and bipolar head.The event was confirmed via clinician review.The exact cause of the event could not be determined.No further investigation for this event is possible at this time.If additional information becomes available to indicate further evaluation is warranted, this record will be reopened.
