斑点犬桡骨、尺骨的X线解剖特征与临床意义

The X-ray Anatomy Features of Radius and Ulna on Dalmatians and Clinical significance

采用X线解剖学方法,对一只成年斑点犬的桡骨、尺骨的形态特征进行了观察和测量,并结合临床进行了分析与讨论。结果显示:成年斑点犬桡骨骨干最窄处直径10 mm、骨髓腔直径3.5 mm,尺骨骨干最窄处直径5 mm、骨髓腔直径1.2 mm。正位X线片中主要是桡骨、尺骨重叠影像,侧位片中近端有部分重叠,但两骨之间界限清楚。了解桡骨和尺骨X线解剖特征对临床有重要意义。

By the methods of X-ray Anatomy, the morphologic features of radius and ulna on an adult Dalmatians were observed and measured, and the features were analyzed and discussed with the clinical. The result was as follow： the diameter of the narrowest part of the radius backbone was 10mm, and the diameter of the bone marrow cavity was 3.5mm. The diameter was 5mm in the narrowest part of ulna backbone, and the diameter of bone marrow cavity was 1.2mm. On X- negative film of the obverse location the overlapping image were observed. And on the film of the profile location part the overlapping image were observed approaching the near end of radius and ulna, and there were clear boundary between radius and ulna. On the clinical medicine it is very important to understand the features about radius and ulna.
