In eight patients, radiographs made after total hip replacement revealed
methylmethacrylate in the soft tissues of the thigh. In one of them the
configuration of the density was that of a vein. In the other seven
patients similar but less extensive soft-tissue densities were seen
postoperatively. One patient had postoperative hypotension which was
thought to be due to a myocardial infarction. In another patient, with a
prior history of congestive heart failure, congestive heart failure
developed again after total hip replacement. The relationship of these
complications to the radiographic observations was not clear.
