CT for determining the results of treatment of XXXX of the wrist.

@entity1 @entity174 @entity1184 @entity170 @entity194 @entity13316
Eighteen CT examinations of the wrist were performed in 13 @entity1 to evaluate the results of treatment for @entity174 . In four cases with metal objects and in seven with cast materials, there was no difficulty achieving adequate CT studies. In 13 cases CT was found to be helpful in determining bony union in the presence of advanced @entity170 . In six cases CT was excellent in evaluating bone-graft incorporation. CT affords improved detection of @entity174 perpendicular to the plane of the scan and also shows small areas of bone disruption, even with @entity170 . Axial CT images can evaluate Lister's tubercle, a bony prominence on the dorsum of the distal radius, for @entity1184 , which can occur secondary to traumatic and degenerative changes. A hypertrophied tubercle can impinge on the extensor pollicis longus tendon and cause @entity194 and disruption. The high cost of CT is offset by the possibility of reducing the @entity1 's period of immobilization and, thereby, the length of time the @entity1 is unable to participate in normal activities. In addition, since CT is often definitive, the number of supplemental or follow-up radiologic procedures or clinical appointments should be reduced. We conclude that CT is useful in evaluating the results of treatment of @entity13316 .
