[Traumatic axial dislocation injury of the carpus and metacarpus with triquetrum fracture. Rare entity or typical injury].
Although there are only 39 reports of compression injuries with axial dislocation of the carpus and metacarpus, there are similar patterns of injury. In all cases the dislocation is located either between the first and second or the third and fourth metacarpals and the corresponding carpal bones so that weak points of the carpal arch can be assumed in these regions. Clinical and radiological findings in a 22-year-old patient with dislocation of the third and fourth metacarpals and a fracture of the os triquetrum of the right hand after compression injury of both forearms with severe soft tissue injuries are described. Wound débridement and subsequent skin grafting were performed. The osseous lesions were reduced and held by two Kirschner wires and an external fixator. Results at follow-up were satisfactory.
