摘要
目的:观察腕关节各结构在不同功能位的断面形态变化规律,为临床MR I诊断腕关节韧带损伤提供解剖学依据。方法:获取腕关节0.2 mm厚的薄层冠状断层标本,并将冠状断层标本与该区的MR I图像进行对照研究。结果:在腕关节的冠状断面,可清楚显示桡尺远侧关节、桡腕关节、腕中关节、腕骨间关节及各关节中韧带的形态特征,并提出腕骨间韧带、三角纤维软骨及桡尺远侧关节韧带在MR I冠状位的最佳显示平面。结论:腕关节的冠状断层解剖研究为腕部MR I影像学诊断提供了形态学依据,对影像学诊断及骨科治疗有重要的价值。
Objective：To sum up sectional morphology of the wrist in various functional positions and to provide sectional anatomical base for clinical MRI diagnosis of wrist joint disorders. Methods： A series of 0.2 mm-thiek eryoseetions of wrist joint specimens were compared with the corresponding MR imaging on the coronal planes. Results：The morphological character of the distal radioulnar joint, radioearpal joint, medioearpal joint,interearpal joints and the ligaments were clearly revealed on the cross-sections of wrist joint, and the optimal MRI coronal plane was proposed to display the interearpal interosseous ligaments,the triangular fibroeartilage and the distal radioulnar articular ligament. Conclusion ：The anatomy on coronal section of wrist joint could provide the morphological base for clinical MRI diagnosis of the wrist disor- ders and it was valuable to medical imaging diagnosis and arthroseopy of the wrist.
