IN HIP-REPLACEMENT IS THERE A CONNECTION BETWEEN INTRAMEDULLARY PRESSURE PEAKS, BONE-MARROW INTRAVASATION AND DEEP-VEIN THROMBOSIS

Deep vein thrombosis still is a severe problem in hip replacement. Bas ed on pathophysiological considerations, it is postulated that there i s a connection between intramedullary pressure peaks, resulting intrav asation of bone marrow, and the induction of deep vein thrombosis. The content of the bone marrow cavity can be considered active where coag ulation is concerned. Intravasation may contribute to the development of deep vein thrombosis. In addition to medicamentous prophylaxis and early mobilization, a surgical technique also helps in the prophylaxis thrombosis. In this technique, intramedullary pressure increases are avoided as far as possible, which consequently minimizes intravasation of the content of the bone marrow cavity.
