Modern cement technique consists of the use of porosity reduction of the cement, a femoral medullary canal plug, injection of the cement using a cement gun, centralization of the stem, and pressurization of the cement. The use of cement in femoral revision is increasing rapidly; however, when there is a major cortical defect, forming and pressurizing the cement column might appear impossible. We describe a surgical technique for sealing such defects with a custom-made, intraoperatively fashioned femoral stent that allows for temporary restoration of the cortical tube of the femur, and therefore full pressurization of the cement.
现代骨水泥技术包括降低骨水泥孔隙率、使用股骨骨髓腔塞、用骨水泥枪注入骨水泥、使假体柄居中以及对骨水泥进行加压。骨水泥在股骨翻修术中的应用正在迅速增加；然而，当存在较大的皮质骨缺损时，形成并加压骨水泥柱似乎是不可能的。我们描述了一种手术技术，即使用定制的、术中制作的股骨支架来封闭此类缺损，该支架可暂时恢复股骨皮质管，从而实现对骨水泥的充分加压。
