To evaluate clinical and radiographic outcome in dogs with caudal cervical spondylomyelopathy (CCSM) treated with an intervertebral fusion cage and locking plates.
Prospective clinical study.
Large breed dogs (n=14) with CCSM.
Dogs had single level cervical spine distraction/fusion performed using an intervertebral cage with a hollow center filled with cancellous autograft and 2 ventrally applied locking plates. Outcome was measured using neurologic scores and radiographic interpretation 6 weeks, 6 months, and 12 months postoperatively.
The surgical procedure was well tolerated in all dogs. Final outcome at 12 months was available in 9 dogs. Five dogs were judged excellent, 1 dog was good, 2 dogs were satisfactory, and 2 dogs were poor because of adjacent segment disease. Four dogs died for reasons unrelated to the procedure. Radiographically, implants remained stable over the entire follow-up period. The disc space continued to fill with an immature pattern of new bone, which showed progressive increase in opacity and quantity. Subsidence of the cage (median 2 m) was detected in 9 dogs at 6 weeks and remained unchanged in those that could be followed further.
Distraction-fusion of single level CCSM in dogs with a combination of intervertebral cage and ventral locking plates is clinically effective and results in successful bony fusion.
评估采用椎间融合器和锁定钢板治疗的尾侧型颈椎病（CCSM）犬的临床和影像学结果。
前瞻性临床研究。
患有CCSM的大型犬（n = 14）。
对犬进行单节段颈椎撑开/融合术，使用中心中空并填充自体松质骨的椎间融合器和2块腹侧应用的锁定钢板。在术后6周、6个月和12个月，使用神经学评分和影像学解释来评估结果。
所有犬对手术耐受性良好。9只犬有12个月时的最终结果。5只犬评定为优秀，1只犬为良好，2只犬为满意，2只犬因相邻节段疾病评定为差。4只犬因与手术无关的原因死亡。影像学检查显示，在整个随访期间植入物保持稳定。椎间盘间隙持续被未成熟的新骨填充，新骨的密度和数量逐渐增加。9只犬在6周时检测到椎间融合器下沉（中位数2毫米），在可进一步随访的犬中下沉情况保持不变。
采用椎间融合器和腹侧锁定钢板联合治疗犬的单节段CCSM撑开融合术在临床上有效，并能成功实现骨融合。
