The case report of a 14-month-old Thoroughbred filly with acute onset of severe right hindlimb lameness is presented. The horse had a severe and sudden abduction of the hindlimbs due to a side effect of an overdose of lidocaine, which had been administered in a constant rate infusion after a colic surgery. Transcutaneous ultrasonography and standing radiography of the pelvis revealed proximal and cranial displacement of the greater trochanter and free bone fragments consistent with an apophyseal avulsion fracture of the greater trochanter. The complete diagnosis was obtained with the horse in a standing position. The filly was euthanatized because of deterioration resulting from the colic condition and of the poor prognosis of the fracture of the greater trochanter. Postmortem evaluation confirmed an apophyseal avulsion fracture of the right greater trochanter. To the authors' knowledge, ultrasonographic and radiographic findings of this fracture have not been described in the standing horse. The diagnosis was reached quite easily with the horse in a normal standing position when the characteristic ultrasonographic and radiographic findings were detected.
本文报告了一匹14个月大的纯种雌马，该马后肢突然严重跛行。这匹马在进行结肠手术后以恒速输注利多卡因，因用药过量产生副作用，导致后肢严重且突然外展。经皮超声检查和骨盆站立位X线摄影显示，大转子近端和头侧移位以及游离骨碎片，符合大转子骨骺撕脱骨折。在马站立位时获得了完整诊断。由于结肠疾病导致病情恶化以及大转子骨折预后不良，对这匹小雌马实施了安乐死。尸检评估证实右侧大转子存在骨骺撕脱骨折。据作者所知，尚未有关于站立位马匹这种骨折的超声和X线表现的描述。当检测到特征性的超声和X线表现时，在马正常站立位时很容易做出诊断。
