Evaluate the risk factors for reluxation and outcomes for dogs with a toggle rod construct.
Retrospective case series.
One hundred twenty-eight client-owned dogs.
Medical records from 2007 to 2018 were reviewed for signalment, history, surgery, and outcome for dogs with a coxofemoral luxation repaired with a commercial toggle rod and nylon monofilament suture construct. Univariate and multiple logistics regression analysis were performed to assess risk factors associated with postoperative luxation. Primary veterinarians and owners were contacted for follow-up via telephone or electronic communication.
The overall complication rate was 24.2%, and the reluxation rate was 14.8%. There was a decreased risk of reluxation when the cause was traumatic in origin (odds ratio [OR] 0.10) or when the lameness was severe at presentation (OR 0.42). Fifteen of 58 (25.9%) owners contacted completed a follow-up survey.
Dogs with nontraumatic, low impact luxations were at a higher risk for reluxation.
Dogs of any body condition with a traumatic coxofemoral luxation are at lowest risk for reluxation.
评估采用Toggle杆固定的犬髋关节脱位复位的危险因素及预后情况。
回顾性病例系列研究。
128只客户拥有的犬。
回顾2007年至2018年采用市售Toggle杆和尼龙单丝缝线固定修复犬髋关节脱位的病历，包括体征、病史、手术及预后情况。进行单因素和多因素逻辑回归分析以评估与术后脱位相关的危险因素。通过电话或电子通讯方式联系主治兽医和犬主进行随访。
总体并发症发生率为24.2%，脱位复发率为14.8%。病因是创伤性时（优势比[OR]0.10）或就诊时跛行严重时（OR 0.42），脱位复发风险降低。联系的58位（25.9%）犬主中有15位完成了随访调查。
非创伤性、低冲击力脱位的犬脱位复发风险更高。
任何身体状况的犬发生创伤性髋关节脱位时，脱位复发风险最低。
