对文献进行综述，以确定双锥形和三锥形种植体的柄下沉水平，以确定在测量方法、下沉的幅度和速度以及临床结果方面是否存在任何差异。所有关于抛光锥形滑杆下沉的研究都已确定。收集了患者的人口学资料、植入物设计、放射学表现、手术技术细节、测量方法和下沉水平，以调查哪些因素与增加下沉有关。在应用纳入和排除标准之后，确定了28篇相关论文。这些研究最初招募了3090个髋关节，其中2099个髋关节在最终随访时可用于放射学分析。患者年龄42~70岁，平均68岁，女性占60.4%，体重指数(BMI)平均27.4 kg/m2(24.1~29.2)。1年、2年、5年和10年的平均沉降量分别为0.97 mm、1.07 mm、1.47 mm和1.61 mm。尽管在所有时间点上，双锥度杆比三度锥度杆的下沉幅度更大，但这在统计学上没有统计学意义(p>；0.05)，也没有使用测量方法(p>；0.05)。我们报告了临床结果和存活率保持良好的下沉水平，但基于文献，不可能确定下沉阈值，超过下沉阈值更有可能失败。关于三个锥度的研究相对较少，但由于没有统计学上的显著差异，本综述中提出的水平可以应用于双锥度和三个锥度设计。引用本文：Efort Open Rev 2021；6：331-342。电话：10.1302/2058-5241.6.200086
The literature was reviewed to establish the levels of stem subsidence for both double and triple-tapered implants in order to determine whether there were any differences in subsidence levels with regard to the methods of measurement, the magnitude and rate of subsidence and clinical outcomes. All studies reporting subsidence of polished taper-slip stems were identified. Patient demographics, implant design, radiological findings, details of surgical technique, methods of measurement and levels of subsidence were collected to investigate which factors were related to increased subsidence. Following application of inclusion and exclusion criteria, 28 papers of relevance were identified. The studies initially recruited 3090 hips with 2099 being available for radiological analysis at final follow-up. Patient age averaged 68 years (42–70), 60.4% were female and the average body mass index (BMI) was 27.4 kg/m2 (24.1–29.2). Mean subsidence at one, two, five and 10 years was 0.97 mm, 1.07 mm, 1.47 mm and 1.61 mm respectively. Although double-tapered stems subsided more than triple-tapered stems at all time points this was not statistically significant (p > 0.05), nor was the method of measurement used (p > 0.05). We report the levels of subsidence at which clinical outcomes and survivorship remain excellent, but based on the literature it was not possible to determine a threshold of subsidence beyond which failure was more likely. There were relatively few studies of triple-tapered stems, but given that there were no statistically significant differences, the levels presented in this review can be applied to both double and triple-tapered designs.
