The quality of the cement layer influences the long-term survival of cemented endoprostheses. However, blood and fluid laminations within the cement layer, which can form during implantation of endoprostheses, lead to the deterioration of bone cement. Since the bone cement is the weakest part in the construction consisting of prosthesis, bone and bone cement, further weakening of the bone cement should be avoided if possible. By means of in vitro studies, three different cementing techniques were tested, measuring quantitatively the amount of fluid within the cement layer after implantation. The least amount of fluid within the cement layer was found in the cement-canal technique, and the highest amount in anterograde cement injection. Retrograde cement injection led to intermediate values.
骨水泥层的质量会影响骨水泥固定型假体的长期存活。然而，在假体植入过程中可能形成的骨水泥层内的血液和液体分层会导致骨水泥性能变差。由于骨水泥是由假体、骨和骨水泥组成的结构中最薄弱的部分，应尽可能避免骨水泥进一步弱化。通过体外研究，测试了三种不同的骨水泥固定技术，定量测量植入后骨水泥层内的液体量。骨水泥层内液体量最少的是骨水泥-髓腔技术，最多的是顺行骨水泥注入法。逆行骨水泥注入法的液体量处于中间值。
