Manufacturer Narrative

This follow-up report is being submitted to relay additional information.Reported event was confirmed by review of medical records and x-rays received.Review of the available medical records identified dislocation of the head after implantation of a left radial head prosthesis.Painful limitation of movement.Large effusion was noted, no sign of infection.Rom 0-10-95°.Cartilage damage noted, head found to be dislocated, locked screw dislocated mediodorsally in the joint.Screw removed, radial head replaced, radial stem left intact.No intraop complications.Post revision radiographs demonstrate a radial head replacement with anatomic alignment and no evidence of implant failure.Pre radiographs demonstrate a displaced screw overlying the level of the proximal ulna.There is no fracture.There appears to be some radiolucency reflecting interval osteolysis along the more proximal aspect of the radial implant and there is interval development of malalignment and partial disassociation of the radial implant head-stem junction.The device history record (dhr) was reviewed and no discrepancies relevant to the reported event were found.Root cause was unable to be determined.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.
