Computed tomography is increasingly utilized for the evaluation of scaphoid fracture, nonunion, and deformity.

We have developed a new technique of positioning patients while performing longitudinal computed tomography of the scaphoid.

With the wrist positioned in radial deviation and neutral flexion, greater patient comfort is provided and immobilization of the wrist is not required.

A reproducible image can be obtained with attention to the alignment of the scanning plane to the longitudinal axis of the scaphoid on the scout image, and verified with the "target sign".

High resolution images, which clearly demonstrate the abnormalities of the scaphoid, can be produced even if the patient has a cast on the wrist or if there is hardware in situ.
