An adult male crossbred dog was referred with a history of a road traffic accident that took place 1 month earlier. Neurological examination revealed paraplegia with absent nociception in the pelvic limbs. On epaxial palpation, significant curvature of the anatomical axis of the spine between the third and fourth lumbar vertebrae was observed, with the presence of a bone end almost piercing the dog's skin. Survey radiographs of the lumbar spine revealed severe dislocation between L3 and L4 vertebrae. During surgery, the spinal cord was not visible between the dislocated segments. Because of difficulties in reducing the lumbar luxation during surgery, vertebrectomy and vertebral shortening were performed. After alignment between vertebrae L3 and L5, eight cortical orthopaedic screws and bone cement were used for fixation. After 30 days, the dog started to use a wheelchair and was considered by its owner to have a good quality of life with no evidence of pain. To the authors' knowledge, this is the first case of severe luxation treated by total vertebrectomy and spine shortening in a dog. This surgery can be considered as an option in the management of severe spine luxation when the spinal cord is physically transected.
一只成年雄性杂种犬因1个月前发生的交通事故前来就诊。神经学检查发现后肢截瘫且盆腔肢体无伤害感受。在轴后触诊时，观察到第三和第四腰椎之间脊柱解剖轴有明显弯曲，有一个骨端几乎刺破狗的皮肤。腰椎的X线平片显示L3和L4椎体之间严重脱位。手术过程中，脱位节段之间看不到脊髓。由于手术中难以复位腰椎脱位，遂进行了椎骨切除术和椎体缩短术。在L3和L5椎体对齐后，使用了8颗皮质骨矫形螺钉和骨水泥进行固定。30天后，这只狗开始使用轮椅，其主人认为它生活质量良好，没有疼痛迹象。据作者所知，这是首例在犬中通过全椎骨切除术和脊柱缩短术治疗严重脱位的病例。当脊髓发生物理横断时，这种手术可被视为严重脊柱脱位治疗的一种选择。
