Radiography and computerized tomography in the diagnosis of incongruity of the distal radio-ulnar joint. A prospective study
DE Mino, AK Palmer and EM Levinsohn
The diagnosis of subluxation or dislocation of the distal radio-ulnar joint
may be difficult to confirm by routine radiographs. We undertook a
prospective evaluation of fifteen patients with acute or chronic pain in
the distal radio-ulnar joint, using both standardized radiographs and
computer assisted tomography. In the absence of a deformity of the distal
end of the radius, a lateral radiograph made with the wrist in the neutral
position accurately revealed incongruency of the distal radio-ulnar joint.
When pain or cast immobilization prevented optimum positioning of the wrist
for radiography, or when a deformity of the distal end of the radius was
present, computer assisted tomography gave a more accurate determination of
the congruency of the joint.
