Abstract：
Recent literature has demonstrated that high-resolution ultrasonographic anatomy of the canine carpus is possible; however, only the structures of the dorsal face were described. The aims of this prospective study were: (1) to describe the normal ultrasonographic appearance of the carpal tendons in sporting Border Collies; (2) to measure the height, length, and thickness of the tendon at the radial ulnar notch level in order to create a baseline reference for the breed, and (3) to describe a standardised protocol to ultrasonographically evaluate the carpal faces and visible tendinous structures. A pilot study based on ten cadaveric front limbs was used to identify the structures. A subsequent clinical phase of the study using twenty-six Border Collies was recorded. The tendons of the Extensor Carpi Radialis, Extensor Digitorum Communis, and Extensor Digitorum Lateralis were identified and followed from the tenomuscular junction to the distal insertion on the dorsal face of the digits. On the lateral face, the tendon of the Extensor Carpi Ulnaris was recognised and followed. On the palmar face, the two heads of the Flexor Carpi Ulnaris tendon ending on the accessory carpal bone, the adjacent Flexor Digitorum Superficialis tendon, and the deep and medially located Flexor Digitorum Profundus tendon were seen and followed. The Flexor Carpi Radialis and the Abductor Pollicis Longus tendons were seen in the medial carpal face. The ulnar notch of the radius was used as the measurement and starting point of the ultrasonography. These data could be used as a standard reference in the case of chronic overuse and trauma-induced changes in the canine carpus.
摘要：
最近的文献表明，犬腕骨的高分辨率超声解剖是可能的；然而，只描述了背面的结构。这项前瞻性研究的目的是：（1）描述运动边境牧羊犬腕腱的正常超声表现；（2）测量身高，长度,和肌腱在桡骨尺骨切迹水平的厚度，以便为品种创建基线参考，和（3）描述一种标准化的协议，以超声评估腕面和可见的肌腱结构。基于十个尸体前肢的初步研究用于识别结构。记录使用二十六个BorderCollies的研究的后续临床阶段。桡侧腕关节的肌腱，扩展数字通信，并确定了手指外侧伸肌，然后从肌腱交界处到手指背面的远端插入。在侧面，识别并随访了尺重肌伸肌肌腱。在掌面，肘节屈肌腱的两个头终止于副腕骨，相邻的指屈肌腱并观察并追踪了位于深层和中部的屈伸肌腱。在腕骨内侧面部可见桡骨腕屈肌和Pollicis和Longus肌腱。桡骨尺骨切迹作为超声检查的测量和起点。在慢性过度使用和创伤引起的犬腕骨变化的情况下，这些数据可用作标准参考。
