Atrophic nonunion ? a radiological case study

This paper reports a rare case of complications following the forearm fracture in a female Italian greyhound aged 8 months. The radiographic examination showed a fracture in the distal one-fifth of the radial bone diaphysis, and a double fracture of the ulna at the distal one-fifth and one-fourth of the diaphysis. Owing to the incidence of other traumas, no improvement in the clinical state, and the persistent motility of the fractured bone fragments, subsequent radiographs were taken after 3, 5, 6, and 18 months after the first examination. Within the 18-month follow-up, no bone union was recorded. The last follow-up examination revealed advanced bone atrophy. The radial bone was severely narrowed and shortened by 50% as compared to the primary length. The ulna bone had nearly atrophied completely.
