title: Non-union of isolated displaced triquetral body fracture--a case report.
abstract: Triquetral fractures are the second most common carpal fractures. Triquetral body fractures are the less common type of triquetral fractures but they can be missed on plain radiographs and a non-union can be associated with considerable morbidity and reduction in functional activities. We report a unique case of displaced isolated triquetral body fracture that was initially missed on plain radiographs and resulted in non-union. The fracture non-union was diagnosed on magnetic resonance imaging and was treated successfully with open reduction and internal fixation using compression screws, without bone grafting, and early mobilisation of the wrist allowing a return to premorbid activity levels. To our knowledge, this has not been previously described in the literature. We advocate early clinical suspicion of triquetral fractures in patients with persistent ulnar-sided wrist pain following trauma, and early evaluation using computed tomography or magnetic resonance imaging.
