Event or Problem Description
It was reported that the surgeon followed surgical technique and grinded the acetabulum, used the 47 trial implant, then implanted the acetabular prosthesis 48, which was very stable.The corresponding e1 liner c-32 was then dismantled, the inside of the acetabulum was cleaned, and the liner implanted.It was found that after knocking down, the liner was still in an unstable state.Repeated attempts were made to implant several times, but was still not stable, so the acetabular prosthesis was removed.There were no additional liners of this size available at the facility, and the surgery could not wait for the same size of implant to be delivered.Since the initial liner could not be driven into the acetabular cup, and there were no other alternative liners of the same size available, the patient's acetabulum was continued to be ground, and a larger acetabular cup and liner were used.The acetabular file was increased by one, and the 50th acetabular cup was implanted, along with the corresponding e1 liner, which was very stable after implantation.The surgery was prolonged by 30 minutes.The patient had no other problems at this time, and there were no contributing patient conditions related to the event.
Additional Manufacturer Narrative
This follow-up report is being submitted to relay additional information.Product was returned and evaluated.A visual examination of the returned product identified that the shell is in decent overall condition.Scratching was observed on the inner radius.There was no damage to the scallop cutouts or locking groove.The liner barb was found damaged in two locations.A poly strand protrudes from the barb in one location, and the other location was gouged such that the material was deformed.Scratching and scuffing are also present on the outer radius.The sidewall exhibits multiple tool marks imprinted into the material.Medical records were not provided.The reported products were reviewed for compatibility with no issues noted.A review of the device history records identified no deviations or anomalies during manufacturing related to the reported event.A definitive root cause cannot be determined.If any further information is found which would change or alter any conclusions or information, a supplemental will be filed accordingly.Zimmer biomet will continue to monitor for trends.
