Computed Tomography and Fluoroscopy versus Radiographic Guidance for Internal Fixation of Central Tarsal Bone Fractures in Nonracing Horses

Abstract

Introduction: Internal fixation of central tarsal bone (CTB) fractures is challenging due to the size and curvature of the CTB. CT-imaging can improve the understanding of fracture configuration and precision of screw placement but may not be available to every surgeon. This study assessed screw placement in simulated dorsomedial-plantarolateral CTB fractures in 10 pairs of cadaver tarsi using two guidance techniques. We hypothesized that CT with fluoroscopy would be superior to radiography in procedure time and precision of screw placement.
