Whyte et al: Use of cannulated screws in the treatment of unicondylar humeral condylar fractures in dogs
Veterinary Surgery 2, 2025

🔍 Key Findings

Study focus: Outcomes of cannulated screw fixation in unicondylar humeral condylar fractures (UHCF) in dogs.
Clinical union rate: 89%
Overall complication rate: 36%

  • Major complication: Most common was screw breakage

Significant risk factor for screw breakage:

  • Body weight >20 kg (statistically significant)

Breed distribution:

  • Spaniels, especially English Springer Spaniels, were most common

No mention of plate augmentation as standard in this cohort
