【摘要】：目的:探讨MRI在客观评价严重股骨滑车发育不良中的作用。方法:回顾性分析30例正常人及根据Dejour形态分型确定的59例(61膝)严重股骨滑车发育不良患者膝关节MRI图像。利用软骨标志测量比较患者组和对照组中股骨滑车沟深度、股骨滑车沟角度、股骨滑车外侧面倾斜度、关节面对称性、股骨内外侧髁对称性和股骨外侧髁与滑车最大宽度之比有无差异。同时分析患者组中各分型间的股骨滑车沟深度和角度有无差异。结果:患者组中股骨滑车沟深度、股骨滑车沟角度、股骨滑车外侧面倾斜度和关节面对称性较对照组有显著统计学差异(P0.05)。患者组内各Dejour分型间,股骨滑车沟深度和股骨滑车沟角度无明显统计学差异。结论:MRI具有显示关节面软骨的优势,在严重股骨滑车发育不良患者中利用软骨标志进行测量能够客观地评价股骨滑车发育不良。
[Abstract]:Objective: to investigate the role of MRI in the objective evaluation of severe femoral trochlear dysplasia. Methods: the knee joint of 30 normal subjects and 59 patients with severe femoral trochlear dysplasia determined by Dejour morphological classification were analyzed retrospectively. MRI image. The depth of trochlear sulcus was measured and compared between the patient group and the control group by using cartilage markers. Angle of femoral trochlear groove, inclination of lateral side of femoral trochlear, symmetry of articular surface, The symmetry of the lateral and lateral femoral condyle and the ratio of the maximum width of the lateral femoral condyle to the trochlear were not different. At the same time, the depth and angle of the trochlear groove in the patients group were analyzed. Results: the depth of the trochlear sulcus of the femur in the patient group was analyzed. The angle of trochlear groove, the inclination of lateral side of femoral trochlear and the symmetry of articular surface were significantly different from those of control group (P 0.05). There was no significant difference between the depth of trochlear groove and the angle of femoral trochlear groove. The measurement of cartilage markers in patients with severe femoral trochlear dysplasia can objectively evaluate femoral trochlear dysplasia.
