THROMBOSIS IN HIP ENDOPROSTHESES - A STUD Y USING COLOR-CODED DUPLEX SONOGRAPHY

After 102 hip replacements in a surgical technique that avoids bone-ma rrow intravasation as much as possible, color-coded duplex sonography revealed thigh thrombi in only 4 cases without any signs of thrombosis . This rate is lower than that found in all other comparable studies. The investigations stress the role of bone-marrow intravasation in the induction of deep vein thrombosis in hip replacement. With an optimal surgical technique, thigh thrombi can be greatly reduced in hip repla cements, which have a higher rate than all other operations.
