X线隧道位测量膝关节骨性关节炎患者股骨髁间窝宽度和高度的临床意义

Clinical significance of width and height of femoral intercondylar notch measured by using knee tunnel view radiograph for patients with knee osteoarthritis

目的:膝关节X线隧道位测量膝关节骨性关节炎患者与健康成人髁间窝宽度与高度,分析髁间窝高度、宽度与骨性关节炎的关系。方法:选取132例健康成人与97例膝关节骨性关节炎患者,进行膝关节X线隧道位摄片,并将所得结果按性别进行分组、比较。结果:健康成人组髁间窝宽度为(19.45±2.76)mm,高度为(27.93±2.75)mm;骨性关节炎组宽度为(17.74±2.14)mm,高度为(22.04±2.43)mm,二者均有明显统计学差异(P<0.05)。结论:骨性关节炎患者的髁间窝宽度与高度明显小于健康成人,膝关节骨性关节炎同髁间窝的狭窄有关;X线隧道位是显示股骨髁间窝一种有临床价值的影像学方法。

Objective To compare the differences in the width and height of the intercondylar notch between healthy adults and osteoarthritis patients by using knee tunnel view radiograph, and to analyze the relationship between the width and height of the intercondylar notch and osteoarthritis. Methods The width and height of the intercondylar notch were measured on 132 healthy adults and 97 osteoarthritis patients by using the knee tunnel view radiograph. The data of all participants were grouped by sex and compared statistically. Results The width of the intercondylar notch of healthy adults and osteoarthritis patients was respectively （19.45±2.76） mm and （17.74±2.14） ram. The height of the intercondylar notch of healthy adults and osteoarthritis patients was respectively （27.93±2.75） mm and （22.04±2.43） mm. Significant differences were found in the width and height of intercondylar notch of healthy adults and osteoarthritis patients （P〈0.05）. Conclusion The width and height of the intercondylar notch of osteoarthritis patients are smaller than those of healthy adults. Osteoarthritis is related to the stenosis of the intercondylar notch. The knee tunnel view radiograph is an imaging method with clinical value in showing the femoral intercondylar notch.
