An in vitro study was dthesigned to measure the effects of variable cement volumes and modified mixing techniques on the monomer leakage after simulated implantation. The cement volume as such was found to be an irrelevant parameter for calculations of the monomer loss from bone cement. The leakage was directly related to the surface area of the cement. Variations in the thickness of the cement mantle from 1 to 5 mm did not affect the leakage. Late cement insertion should reduce the total monomer leakage into the tissues. It is doubtful whether an increased stirring speed during mixing reduces the monomer leakage after implantation.
一项体外研究旨在测量不同骨水泥体积和改良混合技术对模拟植入后单体渗漏的影响。结果发现，骨水泥体积本身并非计算骨水泥单体损失的相关参数。渗漏与骨水泥的表面积直接相关。骨水泥套厚度在1至5毫米之间的变化并不影响渗漏。延迟注入骨水泥应能减少进入组织的单体总量。混合过程中搅拌速度增加是否会降低植入后的单体渗漏尚不确定。
