New clinico-pathophysiological studies on the bone cement implantation syndrome.
Implantation of endoprostheses with bone cement is followed by alterations of the circulation. Intoxication, caused by the monomer of bone cement or pulmonary embolism by intramedullary contents constitute the two mostly accepted pathophysiological hypotheses. Because of the lack of pulmonary and circulatory physiological data a clinical decision concerning the value of the hypotheses was not possible until now. Hip prosthesis implantation was analyzed in 15 patients by measuring equipment controlled by an on-line-computer. The device allowed a high rate of data retrieval. The bone cement implantation syndrome reveals itself as cardiorespiratory sequelae of a disseminated pulmonary embolism which is originating in intramedullary contents, squeezed intravasal. Usual prophylactic methods are revisited.
