To describe the (1) indications, (2) preoperative precautions, and (3) stepwise technical details of modern femoral stem cemented fixation.
Femoral stem cementation provides excellent implant longevity with a low periprosthetic fracture rate among patients with compromised bone quality or aberrant anatomy. Unfamiliarity with the details of modern cementation techniques among trainees who may lack frequent exposure to cementing femoral stems may preclude them from offering this viable option to suitable patients in later stages of their careers. As such, maximizing benefit from cemented femoral stem fixation among suitable candidates is contingent upon the meticulous use of modern cementation techniques. In addition to proper patient selection, modern cementation techniques emphasize the use of (1) pulsatile lavage of the femoral canal, (2) utilization of epinephrine-soaked swabs, (3) vacuum cement mixing, (4) retrograde cement introduction, (5) cement pressurization, and (6) the use of stem centralizers. Furthermore, identifying and optimizing the preoperative status of at-risk patients with pre-existing cardiopulmonary compromise, in addition to intraoperative vigilance, are essential for mitigating the risk of developing bone cement implantation syndrome. Further research is required to assess the utility of cemented femoral stem fixation among younger patients.
描述现代股骨柄骨水泥固定的(1)适应证、(2)术前注意事项以及(3)逐步的技术细节。
对于骨质量受损或解剖结构异常的患者,股骨柄骨水泥固定可提供出色的植入物长期稳定性,假体周围骨折发生率低。在培训学员中,由于他们可能不经常接触股骨柄骨水泥固定操作,对现代骨水泥技术细节不熟悉,这可能使他们在职业生涯后期无法为合适的患者提供这种可行的选择。因此,在合适的候选人中最大限度地从骨水泥固定股骨柄中获益取决于对现代骨水泥技术的精心使用。除了正确的患者选择外,现代骨水泥技术强调使用(1)股骨髓腔的脉冲冲洗、(2)使用肾上腺素浸泡的拭子、(3)真空骨水泥混合、(4)逆行骨水泥注入、(5)骨水泥加压以及(6)使用柄中央定位器。此外,识别并优化术前存在心肺功能不全的高危患者的状态,以及术中保持警惕,对于降低发生骨水泥植入综合征的风险至关重要。还需要进一步研究以评估骨水泥固定股骨柄在年轻患者中的效用。
