Seventy-two lower limb long radiographs were reviewed with respect to mechanical and anatomic axes. A template of an intramedullary tibial guide rod was employed to determine the accuracy of the intramedullary guide in producing ideal tibial cuts (ie, 90 degrees ) and acceptable tibial cuts (ie, 90 degrees +/- 2 degrees ). The mean difference of the angle formed by the 2 axes was 1.84 degrees +/- 1.42 degrees. In our findings, 22.2% of patients would have unacceptable cuts if an intramedullary device were employed for the tibial cut during a total knee arthroplasty. A radiograph showing the whole tibia is required preoperatively to identify varus tibiae that are not suitable for the intramedullary method.
对72张下肢全长X线片进行了力学轴和解剖轴方面的评估。使用髓内胫骨导杆模板来确定髓内导板在制作理想胫骨截骨（即90度）和可接受胫骨截骨（即90度±2度）时的准确性。两轴形成的角度平均差异为1.84度±1.42度。根据我们的研究结果，如果在全膝关节置换术中使用髓内装置进行胫骨截骨，22.2%的患者将会得到不可接受的截骨结果。术前需要一张显示整个胫骨的X线片，以识别不适合髓内方法的内翻胫骨。
