Abstract：
OBJECTIVE: To describe patient characteristics, etiology, treatment outcomes and complications of caudoventral hip luxation (CvHL) in a large cohort of dogs and investigate factors associated with nonsurgical treatment outcomes.
METHODS: Multicenter retrospective case series.
METHODS: A total of 160 client-owned dogs (170 limbs).
METHODS: Medical records from 2003 to 2023 were reviewed for signalment, history, treatment outcomes and complications. Logistic regression was performed to investigate factors associated with nonsurgical treatment outcome.
RESULTS: Low-trauma accidents accounted for 82.9% of cases. Over-represented breeds included poodles (38.1%) and poodle crosses (11.3%). On a per-treatment basis, success rates of closed reduction alone, closed reduction/Ehmer sling, closed reduction/hobbles were 9.1%, 15.2% and 48.8%, respectively. When accounting for repeated attempts using closed reduction alone, Ehmer sling, or hobbles, eventual success rate increased to 10.3%, 18.5% and 61.8%, respectively. Success rate for toggle rod stabilization was 88.2%. Complication rate of hobbles was 31.9% versus 60.6% for Ehmer slings. Use of hobbles (OR:7.62, p = .001, CI:2.23-26.05), treatment by specialist surgeons (OR:2.68, p = .047, CI: 1.01-7.08) and increasing age (OR:1.15, p < .005, CI: 1.08-1.23) were associated with successful nonsurgical treatments.
CONCLUSIONS: Low-trauma etiology, and poodles and their crosses were over-represented in cases of CvHL. Success rate of nonsurgical treatments was lower than previously reported. Hobbles were 7.6 times more likely to be successful when compared to dogs treated without hobbles and remains a viable noninvasive first-line treatment.
CONCLUSIONS: Hobbles are recommended as a low-morbidity first-line treatment for CvHL. An Ehmer sling is not recommended. Toggle rod stabilization is an effective surgical treatment for CvHL.

摘要：
目的：描述患者特征，病因学,在大型队列狗中,足腹侧髋关节脱位(CvHL)的治疗结果和并发症,并调查与非手术治疗结果相关的因素.
方法：多中心回顾性病例系列。
方法：总共160只客户拥有的狗（170只四肢）。
方法：对2003年至2023年的医疗记录进行了审查，历史,治疗结果和并发症。采用Logistic回归分析研究非手术治疗结果的相关因素。
结果：低创伤事故占病例的82.9%。过度代表的品种包括贵宾犬（38.1％）和贵宾犬杂交（11.3％）。在每次治疗的基础上，单独封闭还原的成功率，闭合还原/Ehmer吊索，封闭减少/步履蹒跚为9.1%，15.2%和48.8%，分别。当考虑到仅使用封闭还原的重复尝试时，Ehmer吊带，或者步履蹒跚，最终成功率提高到10.3%，18.5%和61.8%，分别。肘杆稳定成功率为88.2%。绊脚石的并发症率为31.9％，而Ehmer吊索的并发症率为60.6％。使用hobbles（OR：7.62，p=.001，CI：2.23-26.05），专科医生的治疗(OR:2.68,p=.047,CI:1.01-7.08)和年龄增长(OR:1.15,p<.005,CI:1.08-1.23)与成功的非手术治疗相关.
结论：低创伤病因，在CvHL病例中，贵宾犬及其十字架的代表过多。非手术治疗的成功率低于以前的报道。与没有hobbles的狗相比，hobbles成功的可能性是其7.6倍，并且仍然是可行的非侵入性一线治疗方法。
结论：Hobbles被推荐作为CvHL的低发病率一线治疗。不建议使用Ehmer吊带。拨动杆稳定是CvHL的有效手术治疗方法。
