Loh et al: Caudoventral hip luxation in 160 dogs (2003–2023): A multicenter retrospective case series
Veterinary Surgery 4, 2024

🔍 Key Findings

  • Low-trauma events caused 82.9% of CvHL cases; Poodles and poodle-crosses represented 49.4% of cases.
  • Success rate of hobbles (61.8%) was significantly higher than closed reduction alone (10.3%) or Ehmer sling (18.5%).
  • Multivariate analysis found hobbles 7.62x more likely to succeed vs. closed reduction (p = .001).
  • Specialist surgeons had higher success with nonsurgical management (OR: 2.68; p = .047).
  • Older age associated with better outcomes (OR: 1.15 per year; p < .0005).
  • Ehmer sling is not recommended due to high failure and complication rates (60.6%).
  • Toggle rod stabilization had a high surgical success rate (88.2%) with low complication.
  • No link was found between CvHL and hip dysplasia or OA in most cases (only 2/108 showed OA).

Multiple Choice Questions on this study

In Loh 2024 et al., on treatment outcomes for CvHL in dogs, what was the most common etiology?

A. Motor vehicle accident
B. High-velocity trauma
C. Dog bite injury
D. Low-trauma accidents
E. Post-operative dislocation

Answer: Low-trauma accidents

Explanation: Low-trauma events caused 82.9% of CvHL cases, unlike CdHL which is often MVA-related.
In Loh 2024 et al., on treatment outcomes for CvHL in dogs, which nonsurgical method had the highest success rate?

A. Ehmer sling
B. Hobbles
C. Closed reduction alone
D. Femoral head ostectomy
E. Transarticular pinning

Answer: Hobbles

Explanation: Hobbles achieved a 61.8% success rate, the highest among nonsurgical treatments.
In Loh 2024 et al., on treatment outcomes for CvHL in dogs, what was the odds ratio of successful treatment with hobbles vs. closed reduction alone?

A. 2.68
B. 4.20
C. 5.50
D. 7.62
E. 9.90

Answer: 7.62

Explanation: Hobbles were 7.62 times more likely to succeed compared to closed reduction alone.
In Loh 2024 et al., on treatment outcomes for CvHL in dogs, which surgical technique had an 88.2% success rate?

A. Ventral capsulorrhaphy
B. Femoral head ostectomy
C. Total hip arthroplasty
D. Transarticular pinning
E. Toggle rod stabilization

Answer: Toggle rod stabilization

Explanation: Toggle rod stabilization had the highest surgical success rate and was most frequently used.
In Loh 2024 et al., on treatment outcomes for CvHL in dogs, which factor was associated with improved success in nonsurgical treatment?

A. Smaller breed
B. Lateral luxation
C. Use of Ehmer sling
D. Older age
E. Lower bodyweight

Answer: Older age

Explanation: Older dogs were more likely to achieve successful nonsurgical outcomes (OR 1.15 per year).
