  • Title: [Preventing fat embolism syndrome (FES) in implantation of cemented hip endoprosthesis shafts with a trans-prosthetic drainage system (TDS)].

    Journal: Biomed Tech (Berl); 2001 Nov; 46(11):320-4. PubMed ID: 11778316.
    Abstract:
    In vitro studies with the transprosthetic drainage system (TDS) have revealed a reduction in intrafemoral pressure in cemented total hip prosthesis. The aim of the present study was to establish whether the incidence of fat embolic syndrome (FES) is also reduced. Ten patients underwent standardized cemented total hip replacement using TDS under standardized general anaesthesia. The usual peri-operative monitoring measures were extended to include cardiopulmonary monitoring (pulmonary artery catheter, intra-arterial blood pressure) and two-dimensional transoesophageal echocardiography. Previous studies had reported an increased risk for fat embolic syndrome with conventional, and even with vacuum cementing techniques. Our recorded cardiopulmonary data and the data provided by two-dimensional transoesophageal echocardiography show a significant reduction in pulmonary embolism with TDS. This technique can be recommended in particular for high-risk patients (osteoporosis, elderly patients) and the implantation of long femoral stems. On the basis of the clinical data, a new femoral stem allowing the use of the TDS technique is being developed.
