[Prosthetic cement: a vital risk?].

This study analyses the causes of early death among 17/702 patients which received a hip endoprosthese following a fracture of the femoral neck. Among other patients we conducted 25 endoesophageal cardiac ultrasonographies during elective total hip replacement. There is only a bad correlation between the occurrence of embolies and using of cement. Other factors, as the effraction of the medullary canal and the rise of the intramedullary pressure, are important.
