To report overall rate and type of complications and outcomes of cats with coxofemoral luxation managed with hip toggle stabilization (HTS), to compare rate of postoperative complications and outcomes of cats treated with ultrahigh-molecular-weight-polyethylene (UHMWPE) or nylon, and to identify risk factors for reluxation and non-excellent outcomes.
Multi-institutional retrospective cohort study.
Forty-eight client-owned cats.
Medical records of cats that underwent HTS from 2008-2018 using UHMWPE or nylon were reviewed. Univariable and multivariable logistic regression was performed to assess for factors associated with reluxation and non-excellent outcome. Final outcome was obtained from owner questionnaire.
Intraoperative and postoperative complications were recorded in two (4.2%) and 11 (24.4%) cats, respectively. The most common postoperative complication was reluxation (n = 5 [11.1%]). Outcome was classified as excellent in 81.1% and good in 16.2% of cats after a median of 445.5 days (range, 53-3720). No difference in rate of complications or outcomes was identified between UHMWPE and nylon. Performance of additional orthopedic procedures, occurrence of intraoperative complications, and non-performance of capsulorrhaphy were associated with reluxation. Performance of additional non-hip procedures (orthopedic/nonorthopedic) was associated with non-excellent outcome.
Hip toggle stabilization was associated with a low rate of intraoperative complications and reluxation and excellent long-term outcomes in most cats. No difference in rate of postoperative complications or outcomes of cats treated using UHMWPE or nylon was identified. Cats that underwent additional orthopedic procedures had greater risk of reluxation.
Hip toggle stabilization is an effective technique for management of coxofemoral luxation in cats. Comparable results are expected using UHMWPE or nylon.
报告采用髋关节扣锁固定术（HTS）治疗股髋关节脱位的猫的总体并发症发生率和类型以及结果，比较使用超高分子量聚乙烯（UHMWPE）或尼龙治疗的猫的术后并发症发生率和结果，并确定复发和非优良结果的危险因素。
多机构回顾性队列研究。
48 只患猫。
对 2008-2018 年间接受 HTS 治疗的使用 UHMWPE 或尼龙的猫的病历进行回顾性分析。采用单变量和多变量逻辑回归分析评估与复发和非优良结果相关的因素。最终结果通过主人问卷获得。
术中并发症和术后并发症分别记录在 2 只（4.2%）和 11 只（24.4%）猫中。最常见的术后并发症是复发（n=5[11.1%]）。在中位数为 445.5 天（范围，53-3720 天）后，81.1%的猫结果被归类为优良，16.2%的猫结果被归类为良好。在 UHMWPE 和尼龙之间，并发症或结果的发生率没有差异。进行额外的骨科手术、术中发生并发症以及未进行囊切开术与复发有关。进行额外的非髋关节手术（骨科/非骨科）与非优良结果相关。
HTS 与大多数猫的术中并发症和复发率低以及长期优良结果相关。使用 UHMWPE 或尼龙治疗的猫的术后并发症或结果发生率无差异。进行额外的骨科手术的猫复发风险更大。
髋关节扣锁固定术是治疗猫股髋关节脱位的有效技术。使用 UHMWPE 或尼龙预计会有类似的结果。
