中文摘要:
      目的:通过对比分析实验组(盘状半月板组)和对照组(正常膝关节组)在X线片上的相关测量数据和指标,从而论证运用X线片诊断膝关节盘状半月板的可行性?方法:选取122例盘状半月板患者和122例正常膝关节志愿者进行膝关节X线正位片的拍摄并测量以下变量:腓骨小头到胫骨平台平面的距离(A),外侧关节间隙的距离(B),外侧髁间结节的高度(C),外侧髁间结节的顶点到股骨外侧髁的距离(D),内侧髁间结节的高度(E),股骨内外侧髁的旋距(F,G),外侧髁间结节的倾斜度(α),股骨外侧髁的倾斜度(β)?分析两组数据之间是否存在统计学差异,并应用比值来减少个体差异对分析结果带来的影响?结果:实验组中A?B?C?D?F?A/B和B/C与对照组对应指标存在明显统计学差异(P < 0.05)?其中A/B和B/C的截止值最为突出,它们的受试者工作曲线(ROC)曲线下面积是所有指标中最高的两个?结论:实验组和对照组在X线片上测量的大部分变量存在明显的统计学差异,尤其是A/B和B/C,其敏感性?特异性和准确性都相当高,这使得运用X线片诊断和筛选盘状半月板变得可行?
英文摘要:
      Objective:To prove that it is feasible to diagnoze discoid lateral meniscus in radiographs by analysis of plain radiographic findings of discoid lateral menisci with matched controls in a quantitative method.Methods:Total 122 consecutive patients,who were diagnosed with discoid lateral meniscus (discoid group)by magnetic resonance imaging(MRI)and arthroscopy,and 122 age-and sex-matched controls with normal medial and lateral menisci on the basis of MRI findings were included. Each plain radiograph was evaluated from the anteroposterior view for the following variables:height of the fibular head(A),lateral jointspace distance (B),height of the lateral tibial spine (C),obliquity of the lateral tibial plateau (α),obliquity of the lateral femoral condyle (β),distance from the lateral tibial spine to the lateralfemoral condyle (D),height of the medial tibial spine(E),chordal distance of the femoral condyle (F,G),the A/B,B/C and the F/G. Statistical analyses were used to determine the differences between the two groups. Results:A significant difference was found in the A,B,C,D,F,A/B and B/C between the two groups. The difference in cut-off values of A/B and B/C was most significant. At the same time,the roc curve area of the A/B and B/C ranked highest among all the results. Conclusion:There were significant differences in the variables,especially the A/B and the B/C,between plain radiographic findings of discoid lateral meniscus patients and normal controls. The results of the A/B and the B/C showed a positive impact on the diagnosis of discoid lateral meniscus in this research. These findings enable radiographs to screen for discoid lateral meniscus.
