Abstract
As computerized axial tomography (CT) has evolved, the number of clinical applications has also grown. Originally used for imaging of the brain, CT has now found much use in the examination of the extremities. It was our intention in the present study to apply computerized techniques to re-create a three-dimensional image, that is, to take the data from forty-five transverse cuts and make a representational image of the bone and project it on a television screen. Once accomplished, it should be technically feasible to rotate the reconstructed bone on a screen in ten degree increments such that all sides could be observed. In this manner rapid assessment of the fracture or dislocation could easily be obtained visually.
