It was reported that the vivacit g7 polyethylene liner did not fit into the cup after attempting implantation.The surgeon used an anchorage technique that has worked in the past with the stem and the trial as well as with the acetabular components.After the technique is performed, a correction joint test is performed and checked with a luxation.During the luxation test, it was found that the polyethylene insert jumps and detaches from the acetabular component.There was no additional attempt to insert the liner.There was no reported harm or impact to the patient.No delay.
