Unusual Combination of a Fracture Monteggia Equivalent With Post-traumatic Radial Artery Pseudoaneurysm in a Child: A Case Report and Review of Literature.

CASE: We report a unique case of a combination of forearm fracture and traumatic radial artery pseudoaneurysm in an 8-year-old child. The fracture pattern was a Monteggia equivalent with a mid-diaphyseal ulnar fracture and a radial neck fracture with displacement of the distal radial diaphyseal fracture fragment. The pseudoaneurysm, which probably developed after vigorous manipulation by a bonesetter, thrombosed spontaneously, and the fracture was managed nonoperatively with a good outcome.

CONCLUSION: Pseudoaneurysm of the radial artery is a rare phenomenon associated with fracture in a child. A history of vigorous manipulation of displaced fracture fragments in the vicinity of a major vessel should raise suspicion of this possible complication.
