To report the radiographic and clinical outcome of an intervertebral bone cement plug technique for the management of disc-associated cervical spondylopathy in Dobermann Pinscher dogs.
Retrospective study of 52 Dobermann Pinscher dogs.
A variable degree of cement plug subsidence with loss of vertebral distraction was evident in all dogs (n = 40) that were radiographed >6 weeks postoperatively. In no case was there definitive evidence of vertebral body fusion. Eight dogs had a sudden deterioration in neurological status, cervical hyperaesthesia, or both between three days and 12 weeks following surgery that was considered to be implant-associated; six of these dogs were euthanatized. Following surgery, 43/52 dogs were considered to be neurologically normal or to have improved, however, nine of 43 subsequently deteriorated due to adjacent segment disease. At the long-term follow-up, 34 dogs were considered to be neurologically normal or to have improved. Twenty-nine dogs were dead by the end of the study period.
Intervertebral bone cement plug surgery results in an initial improvement in clinical signs in the majority of Dobermann Pinschers with disc-associated cervical spondylopathy. However, it fails to maintain vertebral distraction or achieve vertebral body fusion, and is associated with acute implant complications, additional cervical disc protrusions or mortality in a significant proportion of cases.
报告采用椎间骨水泥填充技术治疗杜宾犬椎间盘相关性颈椎病的影像学和临床结果。
对52只杜宾犬进行回顾性研究。
在术后超过6周进行X线检查的所有犬只（n = 40）中，均明显出现不同程度的骨水泥填充下沉及椎体撑开丢失。无一例有明确的椎体融合证据。8只犬在术后3天至12周之间出现神经状态突然恶化、颈部感觉过敏或两者皆有，被认为与植入物相关；其中6只犬实施了安乐死。术后，43/52只犬被认为神经功能正常或有所改善，然而，43只中的9只随后因相邻节段疾病而病情恶化。在长期随访中，34只犬被认为神经功能正常或有所改善。到研究结束时，29只犬死亡。
椎间骨水泥填充手术可使大多数患有椎间盘相关性颈椎病的杜宾犬的临床症状得到初步改善。然而，它无法维持椎体撑开或实现椎体融合，并且在相当一部分病例中会出现急性植入物并发症、额外的颈椎间盘突出或死亡。
