This report is being resubmitted for an incident that occurred earlier.The articulating sphere subcomponents were returned disassembled from the implants.Initial observation showed one of the spheres measuring undersized on both the implant width between the sphere flats and sphere nubs, but this is likely due to noted wear on the part from disassembly.A large amount of damage is visible on the other sphere.The imaging provided show the implant placed at l4/l5 appearing to be off center laterally and the implant endplates do not appear parallel to the shot.Additional information provided that this could be due to the angle of the c-arm when the shot was taken, and may not indicate that the implant doesn't have proper endplate contact with the l4/l5 vertebral bodies.The l3/l4 implant appears to be slightly over-medialized, but it is not possible to definitively tell with the provided image.No determinations could be made as to the cause of the reported issue.The following sections have been updated for this supplemental report: b4, e1, h2, h6, h10.
