🔍 Key Findings

• Aiming device provided comparable trajectory accuracy to fluoroscopy, especially in right limbs (1.9° vs. 3.4°, p = .0128).
• Eccentricity (deviation from condylar center) was lower with fluoroscopy (3.1 mm vs 4.2 mm, p = .0017), making fluoroscopy more precise.
• Odds of joint infringement were 8× higher with the aiming device, though not statistically significant (p = .0575).
• Residents had greater screw trajectory deviation than diplomates (p = .0366), highlighting impact of experience.
• Aiming device procedures took less time than fluoroscopy in some scenarios, particularly for right limbs with right-handed surgeons.
• Fluoroscopic procedures had more pin/drill attempts, increasing risk of glove puncture and potential aseptic breaks.
• Mean deviation angles in both groups (<3.5°) were within acceptable range to avoid intracondylar fracture gap.
• Cadaver model used large-breed, healthy adult dogs, not small-breed immature dogs, limiting generalizability.
