In a 7-year-old Doberman Pinscher with an atactic gait, neurologic examination revealed tetraparesis, conscious proprioceptive deficits, and rigid ventral flexion of the neck. Radiography and myelography revealed a ventral, extradural, dynamic compressive lesion between C6 and C7. Distraction decompression was performed, using cancellous bone screws and methylmethacrylate. After initial improvement, clinical signs recurred 2 weeks after surgery and progressed until the dog was euthanatized 6 weeks after surgery. Postmortem myelography revealed an extradural compressive lesion adjacent to the implant, between C5 and C6. Secondary compressive lesions induced by surgical or biomechanical alterations of the cervical portion of the spine may be complications of treatment of caudal cervical spondylomyelopathy.
一只7岁的杜宾犬出现共济失调步态，神经系统检查发现四肢轻瘫、本体感觉障碍以及颈部僵硬腹屈。X线摄影和脊髓造影显示C6和C7之间存在一个腹侧、硬膜外、动态压迫性病变。采用松质骨螺钉和甲基丙烯酸甲酯进行撑开减压。术后初期有所改善，但术后2周临床症状复发并逐渐加重，直至术后6周对该犬实施安乐死。尸检脊髓造影显示在植入物附近C5和C6之间存在硬膜外压迫性病变。脊柱颈部手术或生物力学改变引起的继发性压迫性病变可能是尾侧颈椎病治疗的并发症。
