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.
三角骨骨折是第二常见的腕骨骨折。三角骨体部骨折是三角骨骨折中较不常见的类型，但在普通X线片上可能会漏诊，骨折不愈合可能会导致相当大的发病率和功能活动下降。我们报告了一例独特的孤立性三角骨体部移位骨折病例，该病例最初在普通X线片上漏诊，导致骨折不愈合。骨折不愈合通过磁共振成像诊断，并成功进行了切开复位内固定，使用加压螺钉，未进行植骨，早期进行腕关节活动，使患者恢复到病前的活动水平。据我们所知，此前文献中尚未有过此类描述。我们主张对于外伤后持续尺侧腕部疼痛的患者，应早期临床怀疑三角骨骨折，并早期使用计算机断层扫描或磁共振成像进行评估。
