Radiologic aspects of the Galeazzi lesion.

In lesions of the forearm that included a fracture of the distal two thirds of the radial shaft, a concomitant disruption of the distal radio-ulnar joint was found in 20 out of 38 cases. In 15 cases a typical Galeazzi lesion was present. Dislocation of the distal radio-ulnar joint frequently goes unrecognized. The clinical significance of a lesion in the distal radio-ulnar joint is related to its prognostic value.
