- Abstract
Objective To compare the precision of computer-assisted surgery with a conventional technique (CV) using a special guiding device for screw insertion into the distal sesamoid bone in horses. Study Design In vitro experimental study. Sample Population Cadaveric forelimb specimens. Methods Insertion of a 3.5 mm cortex screw in lag fashion along the longitudinal axis of intact (non-fractured) distal sesamoid bones was evaluated in 2 groups (8 limbs each): CV and computer-assisted surgery (CAS). For CV, the screw was inserted using a special guiding device and fluoroscopy, whereas for CAS, the screw was inserted using computer-assisted navigation. The accuracy of screw placement was verified by radiography, computed tomography, and specimen dissection. Results Surgical precision was better in CAS compared with CV. Conclusion CAS improves the accuracy of lateromedial screw insertion, in lag fashion, into the distal sesamoid bone. Clinical Relevance The CAS technique should be considered for improved accuracy of screw insertion in fractures of the distal sesamoid bone.
