Computed tomography of the hand and wrist

CT plays a limited but distinct role in the evaluation of the hand and wrist. It is most useful in assessing bone and joint anatomy and has only a secondary role in soft tissue abnormalities. The clearest value of CT is in assessing trauma and post-traumatic complications, such as malunion, nonunion, or avascular necrosis, where careful attention to position and technique can yield important information not otherwise obtainable.
