This diagram outlines the process by which decisions were made, relating to surgical planning and to the relevance of CT.

This chart details the distribution of fracture locations included in this study.
Fig 3.
These are radiographic and CT images of a case in which CT was of major relevance to surgical planning.
These images demonstrate radiographic evidence of a fracture of the proximal phalanx in sagittal and frontal planes and CT images confirm this but also highlight extensive distal fissure lines which were not radiographically appreciable. These additional findings significantly alter what is possible in terms of surgical repair.

These are images of a carpal fracture where CT is of major significance.
Following radiography the surgical plan had involved arthroscopic fragment removal, however following the CT diagnosis of severe comminution and partial joint collapse, the only viable surgical option was carpal arthrodesis. The severe comminution is labelled on this image.

This figure demonstrates there to be no significant difference in relevance of CT on different fracture types where each group has been compared to the phalangeal fractures group.
