A female Holstein cow presented with lameness in the left hind-limb, having suffered a fracture within the distal phalanx distal to the distal interphalangeal joint. The lesion was visualized as a radiolucent gap on a lateral radiograph and a hypoechoic gap on an ultrasonogram in which the hyperechoic bony line disappeared. Using regular ultrasonographic examinations, the healing of the fracture could be characterized by increased echogenicity inside the gap and the formation of a hyperechoic bony bridge. Ultrasonography can provide earlier evidence compared with that provided by radiography of the healing process of a fractured distal phalanx.
一头雌性荷斯坦奶牛出现左后肢跛行，其远端指骨在远侧指间关节远端发生骨折。在侧位X线片上，病变表现为一条透光间隙，在超声检查中则表现为低回声间隙，其中高回声骨线消失。通过定期超声检查，骨折愈合的特征表现为间隙内回声增强以及高回声骨桥形成。与X线摄影相比，超声检查能够为远端指骨骨折愈合过程提供更早的证据。
