Evaluation of the humpback scaphoid by computed tomography in the longitudinal axial plane of the scaphoid.

The deformity known as the humpback scaphoid is difficult to visualize on radiographs. Three patients were studied by imaging with computerized axial tomography (CT scan) in the true longitudinal axis of the scaphoid. This projection demonstrates the anatomy, allowing assessment of fractures, the humpback deformity, and the shape of the scaphoid after grafting.
