Anderson et al: Humeral condylar fractures and fissures in the French bulldog
Veterinary Surgery 1, 2023

🔍 Key Findings

  • Lateral humeral condylar fractures (LHCF) were most common, comprising 63.6% of cases.
  • Transcondylar screw (TCS) + K-wire(s) fixation had a 7.62x higher risk of major complications compared to other methods (p = .009).
  • All cases of TCS migration occurred in the TCS + K-wire group; none occurred with plate fixation.
  • Overall complication rate was 40.9%, with 29.5% being major and requiring intervention.
  • Contralateral humeral intracondylar fissures (HIF) were found in 58.1% of French Bulldogs with CT data.
  • No significant association between age and presence of HIF, but fissure length increased with age (R = 0.47, p = .048).
  • Younger, lighter dogs had higher complication and screw migration rates, possibly due to softer bone and smaller condyles.
  • TCS + plate fixation had the lowest complication rate, suggesting biomechanical superiority.

Multiple Choice Questions on this study

In Anderson 2023 et al., on French Bulldogs with humeral condylar fractures, what fixation method was associated with the highest risk of major complications in French Bulldogs?

A. Single transcondylar screw
B. Epicondylar plate only
C. Transcondylar screw + K-wires
D. External skeletal fixation
E. Cerclage wiring

Answer: Transcondylar screw + K-wires

Explanation: This combination had a 7.62x higher risk of major complications (p = .009).
In Anderson 2023 et al., on French Bulldogs with humeral condylar fractures, what percentage of French Bulldogs had a humeral intracondylar fissure (HIF) in the contralateral limb when CT was performed?

A. 22%
B. 35%
C. 43%
D. 58%
E. 71%

Answer: 58%

Explanation: HIFs were found in 58.1% of dogs with available contralateral CT data.
In Anderson 2023 et al., on French Bulldogs with humeral condylar fractures, which fixation method was associated with **no** cases of transcondylar screw (TCS) migration?

A. TCS + supracondylar K-wires
B. TCS + plate
C. TCS alone
D. TCS + external fixator
E. TCS + cerclage wire

Answer: TCS + plate

Explanation: No migration was observed in the TCS + plate group.
In Anderson 2023 et al., on French Bulldogs with humeral condylar fractures, which fracture configuration was most common?

A. Medial condylar fracture
B. Lateral condylar fracture
C. Bicondylar fracture
D. Oblique condylar fracture
E. Transverse supracondylar fracture

Answer: Lateral condylar fracture

Explanation: LHCF was the most frequent, representing 63.6% of fractures.
In Anderson 2023 et al., on French Bulldogs with humeral condylar fractures, which factor was **not significantly associated** with the presence of a contralateral HIF?

A. Younger age
B. Fissure length
C. Breed (French Bulldog)
D. CT availability
E. Condyle width

Answer: Younger age

Explanation: HIF presence was not significantly more common in younger dogs (p = .129).
