Canine cadaveric forelimbs (136) were randomly assigned to either treatment (aiming device) or control (fluoroscopic-guided) groups, and to either diplomate or resident for humeral transcondylar screw placement. Each limb underwent a transcondylar humeral screw placement from a lateral to medial direction. Digital radiography was used to evaluate screw trajectory, measured as deviation from the epicondylar line, and eccentricity on the humeral condyle. Procedure time, difference in outcome based on experience level, and complications were recorded. In the right limb, screw trajectory with the aiming device was decreased compared to fluoroscopy. There was no difference of accuracy between leg laterality with fluoroscopy. Screw trajectory was increased with resident versus diplomate procedures. Eccentricity deviation was decreased in fluoroscopy groups. The findings of this current study suggest that the universal aiming device produced accurate transcondylar screws with comparable results to fluoroscopic- guided methods.
