Manufacturer Narrative

The devices were returned for evaluation.The stem taper had signs of wear.The neck of the stem had signs of impingement.There were tissues ingrown on the beaded surface.The head had scrape marks on the articulating surface most likely from multiple dislocations.The female taper had black debris on the inside of it.The liner has a large gouge on the articulating surface most likely from the stem articulating on it after the head had disassociated from the stem.The shell had wear marks from some type of rubbing on the rim surface most likely from the dislocation and disassociation of the head.The device history records have been reviewed and did not identify any deviations/anomalies.These devices are used for the treatment of the patient.There are no other complaints for the device part and lot combination listed in this complaint.The patient had been noted to have two prior dislocations before this occurrence of dislocation with t he femoral head disassociating from the stem.With the provided information it is likely that the femoral head had loosened over the prior two dislocations which allowed the femoral head to disassociate during the latest dislocation.However, a definitive root cause for the dislocation could not be identified.
