Five mute swans (Cygnus olor) were presented with inability to stand or with abnormal positioning of a leg. Clinical examinations indicated the possibility of femoral fractures or coxofemoral luxations. The suspected diagnosis was proven by means of computed tomography (CT), while superimposition of gastrointestinal contents or other artefacts limited radiographic diagnosis in three birds. A typical CT sign for lesions of the coxofemoral joint apart from femoral displacement was haemorrhage within the pelvic bones (especially around the acetabulum), found in four of the five birds. Small femoral head avulsion fractures could be detected only with CT.
五只疣鼻天鹅（Cygnus olor）出现无法站立或腿部姿势异常的情况。临床检查表明可能存在股骨骨折或髋关节脱位。通过计算机断层扫描（CT）证实了疑似诊断，而三只鸟的胃肠道内容物重叠或其他伪影限制了X线诊断。除股骨移位外，髋臼关节病变的典型CT征象是骨盆骨内出血（尤其是髋臼周围），五只鸟中有四只出现这种情况。只有通过CT才能检测到小的股骨头撕脱骨折。
