His follow-up report is being submitted to relay additional information.D10: revitan®, proximal part, cylindrical, uncemented, 65, taper 12/14 item number 0100402065 lot 2799951.Dural alpha insert w rim oo/32 item number 0100013515 lot 2602123.Sulox-hd 32 l 12/14 item number 173207 lot 2803430.Alloft-s alloclassic shl 64/oo item number 4271 lot #2781144.The revitan stem was returned for investigation and the connection pin of the distal stem is fractured.The sulox head is still mounted on the taper of the proximal part.The sulox head shows some metal transfer on the surface, but it is overall inconspicuous.No bone ongrowth can be seen on the anchoring surface of the proximal part.On the medial and lateral sides, polished areas are visible, indicating possible loosening and movement against the bone.On the anterior and posterior side as well as on the neck of the taper, some scratches are visible, most likely due to revision surgery.The characteristics on the fracture surfaces point to a fatigue fracture with the origin located on the lateral side.Signs of bone attachments can be found on the most distal area of the distal part.The lateral and anterior sides show damage from revision surgery.A review of the device manufacturing records confirmed no abnormalities or deviations.Review of the complaint history identified additional similar complaints for the reported item and the part and lot combination.Complaints are monitored per complaint trending process in order to identify potential adverse trends.Medical records were provided and reviewed by a health care professional.The patient underwent an initial left total hip arthroplasty on unknown date with unknown product due to unknown reason.After that in 2015 the patient had a first revision due to infection and zimmer biomet products were placed.Subsequently, eight (8) years after implantation the patient underwent a second revision surgery due to implant fracture.During the revision implant fracture confirmed.Noted adhesions, bony ingrowth in distal stem and cerclage wires, and metallotic synovitis.The stem, taper, and head were exchanged with competitor components and a zb liner placed without complications.An ap overview of the pelvis taken before second revision surgery was provided and shows implant fracture at the connection pin between the distal and proximal part.Based on the investigation, a fracture of the connection pin of the revitan stem can be confirmed.The characteristics of the fracture surfaces point to a fatigue fracture.The cause may be multifactorial, consisting of patient- and procedure-related factors.Nevertheless, with the information provided, we are unable to provide any definitive conclusions as to the root cause of the reported issue.If any further information is found which would change or alter any conclusions or information, a supplemental report will be filed accordingly.Zimmer biomet will continue to monitor for trends.
