Manufacturer Narrative

Reported event: an event regarding instability involving a ceramic 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 remained implanted.Clinician review: a review of the provided medical records by a clinical consultant indicated: based upon the information given to me and the supporting documentation i cannot confirm that this event did occur.As to the root cause of the event, this cannot be determined since i cannot discern any adverse impact on the patient related to the episode of care.X-rays and office notes would be helpful in this regard.Taking into consideration all of the material subsequently submitted, it does not change my previously stated opinion.The most important information not provided are patient¿s postoperative office notes by dr.And postoperative x-rays taken with proper positioning.It is well-known that patients who have been given an increased offset following total hip replacement can experience symptoms consistent with lateral hip pain and trochanteric bursitis.I am not saying that this has happened in this case, but further documentation, notes and x-rays would be needed in order to make a final appraisal.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: the exact cause of the event could not be determined because insufficient information was provided.Further information such as return of the device, pathology reports as well as patient history and follow-up notes are needed to complete the investigation for determining root cause.No further investigation for this event is possible at this time.If devices and / or additional information become available to indicate further evaluation is warranted, this record will be reopened.
