Arthrography is a useful method to prove the loosening of the cup after total hip replacement. Contrast medium seeping between the bone and acrylic is an unequivocal sign of loosening. False positive diagnoses are unknown. Because of the risk of infection, arthrography is only indicated, if plain films and push-pull-roentgenograms are not significant. Possible errors and complications are discussed.
