Cement pressurization is critical to achieving optimal results in cemented arthroplasty of the hip. An in vitro experiment using plastic femoral models (10 per group) was undertaken to measure the pressures developed by 3 cementing systems: the Howmedica Mark 1 (Stryker Howmedica, Limerick, Ireland) and DePuy Cemvac retrograde cementation systems (DePuy CMW, Blackpool, UK), and a novel antegrade system consisting of a 60-mL catheter-tipped syringe and a Miller proximal femoral seal (Zimmer Ltd, Swindon, UK). The mean pressure was higher for the syringe system (161.45 +/- 28.9 kPa) than the Mark 1 (103.51 +/- 22.0 kPa) or Cemvac (92.65 +/- 30.7 kPa) systems (P = .0001). In addition, fewer cement mantle defects were seen with the syringe system (1, interquartile range [IQR] 1-2) than the Mark 1 (3, IQR 2-4) or Cemvac (3, IQR 1-3) systems (P = .0256).
在髋关节骨水泥型关节置换术中,骨水泥加压对于获得最佳效果至关重要。进行了一项体外实验,使用塑料股骨模型(每组10个)来测量3种骨水泥注入系统产生的压力:豪美迪克Mark 1型(史赛克豪美迪克公司,爱尔兰利默里克)和迪普伊Cemvac逆行骨水泥注入系统(迪普伊CMW,英国布莱克浦),以及一种新型顺行系统,该系统由一个60毫升带导管的注射器和一个米勒股骨近端密封装置(捷迈有限公司,英国斯温顿)组成。注射器系统的平均压力(161.45±28.9千帕)高于Mark 1型(103.51±22.0千帕)或Cemvac系统(92.65±30.7千帕)(P = 0.0001)。此外,与Mark 1型(3个,四分位数间距[IQR] 2 - 4)或Cemvac系统(3个,IQR 1 - 3)相比,注射器系统出现的骨水泥壳缺陷更少(1个,IQR 1 - 2)(P = 0.0256)。
