K. Wenda et al., IN HIP-REPLACEMENT IS THERE A CONNECTION BETWEEN INTRAMEDULLARY PRESSURE PEAKS, BONE-MARROW INTRAVASATION AND DEEP-VEIN THROMBOSIS, Der Orthopade, 24(2), 1995, pp. 114-122
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.
