The results of these experiments show that an increase in the intramedullary pressure (IMP) can lead to embolization of bone marrow contents via the venous drainage system along the linea aspera. A vacuum applied distally to the medullary canal is very effective for filling the diaphyseal tube with cement. The cancellous bone honeycombs of the proximal metaphysis, however, can only be filled if the bone sponge is tunneled at the level of the femoral calcar; a proximal vacuum then yields filling of the cancellous bone framework with bone cement. In order to fill the weight-bearing spongious framework of the pelvic bone with cement, the acetabular cavity should be sealed with a rubber ring and vacuum applied proximo-laterally to the ilium, thereby giving an extremely high suction pressure.
这些实验结果表明，髓内压力（IMP）的增加可导致骨髓内容物通过沿粗线的静脉引流系统发生栓塞。在髓管远端施加真空对于用骨水泥填充骨干管非常有效。然而，只有当骨松质在股骨距水平处打通隧道时，近端干骺端的骨小梁蜂窝才能被填充；然后在近端施加真空可使骨水泥填充骨小梁框架。为了用骨水泥填充骨盆骨的负重松质框架，髋臼腔应用橡胶圈密封，并在髂骨近端外侧施加真空，从而产生极高的抽吸压力。
