Value of 3D CT imaging in fractured os calcis

The authors report their experience with 3D computed tomography (CT) in 23 patients with fractured os calcis (several types of fractures) in comparison to classical 2D CT. The diagnostic accuracy was not found to be improved by the three-dimensional representation. 3D CT is affected by reconstruction artifacts and strongly depends on the choice of threshold. However the 3D visualization is appreciated by the surgeons.
