摘要
[目的]探讨重建膝关节磁共振(magnetic resonance imaging,MRI)图像测量近端胫腓关节(proximal tibiofibular joint,PTFJ)倾斜角的可行性与可靠性。[方法]共35例内侧间室OA患者(35膝)纳入本研究,行MRI测量腓骨倾斜角(MRI measured fibular inclination angle,M-FIA)和X线测量腓骨倾斜角(X-ray measured fibular inclination angle,X-FIA)测量,评估M-FIA的信度,以及M-FIA与X-FIA之间的差异,采用Bland-Altmann分析法评估两者的一致性。[结果]M-FIA测量的观察者内与观察者间组内相关系数(intraclass correlation coefficient,ICC)分别为0.97和0.90,为一致性优异信度优异。X-FIA和M-FIA两种测量方法的测量值间差异无统计学意义[(26.9±7.6)°vs(26.6±7.5)°,P=0.244]。M-FIA与X-FIA的95%一致性界限为(-0.3±2.8)°。[结论]重建膝关节MRI图像来测量PTFJ倾斜角是可重复的技术。M-FIA与X-FIA可以相互替代。
[Objective]To investigate the feasibility and reliability of fibular inclination angles of proximal tibiofibular joint(PTFJ)mea-sured by magnetic resonance imaging(MRI)reconstruction of the knee.[Methods]A total of 35 patients(35 knees)with medial knee osteoar-thritis were included in this study.The MRI measured fibular inclination angle(M-FIA)and X-ray measured fibular inclination angle(XFIA)were conducted to present the inclination of PTFJ.The reliability of M-FIA and the differences between M-FIA and X-FIA were evalu-ated,and the consistency of the two measures was assessed by Bland-Altmann analysis.[Results]The intraclass correlation coefficient(ICC)of intra-observer and inter-observer reliability measured by M-FIA were of 0.97 and 0.90,respectively,indicating excellent consistency re-liability.There was no significant difference between the measured values of X-FIA and M-FIA[(26.9±7.6)°vs(26.6±7.5)°,P=0.244].In term of Bland-Altmann analysis,the 95%agreement limit between M-FIA and X-FIA was of(-0.3±2.8)°.[Conclusion]The knee MRI re-construction used to measure PTFJ inclination is a reproducible technique.M-FIA and X-FIA can be substituted for each other.
