Interfragmentary compression in a feline sacroiliac luxation model: biomechanical comparison of cannulated compression headless screws and cortical screws applied in positional or lag fashion

Key Points

• This research aims to assess interfragmentary compression effectiveness of different screw types in a feline sacroiliac luxation model.
• Conducted ex vivo static testing under controlled conditions
• Compared three types of screws: cannulated compression headless screws, cortical screws
• Evaluated biomechanical performance of screws in both positional and lag configurations.
• No statistically significant differences in interfragmentary compression across the screw types
• Findings challenge existing recommendations for using compression screws in feline sacroiliac luxation treatment.
