Circulating tissue thromboplastin during hip surgery.
An immunoradiometric assay for tissue thromboplastin has been established. Blood levels in 6 patients undergoing total hip replacement have been determined. In 3 patients, high levels of circulating apoprotein III were found at various stages of the operation, showing a release of tissue thromboplastin chiefly during impaction of the prosthesis into the femoral bone. The other 3 patients had low or undetectable levels.
