The scaphoid is the commonest fractured carpal bone, but excluding a scaphoid fracture with plain radiographs is difficult. Other imaging modalities are being increasingly evaluated in the management of scaphoid injuries. MRI has been shown to be of considerable value in the adult population but there have been limited studies of its use in children.
To evaluate the role of MRI in the acute management of suspected scaphoid injuries in children.
Fifty-six children (57 injuries) who had a suspected scaphoid injury underwent MRI within 10 days of their initial trauma. The results of MRI were used to dictate management of the injury.
In 33 (58%) of the 57 injuries, MRI was normal and the patient was discharged from care. In 16 cases (28%), a fractured scaphoid was diagnosed and appropriate treatment started early. Additionally, other fractures around the wrist joint and ganglion cysts were demonstrated on MRI.
MRI of acute scaphoid injuries in children significantly alters management. Those children with normal scans are discharged earlier. Scaphoid fractures are confirmed earlier and other pathological conditions are also detected.
舟状骨是最常见的腕骨骨折部位，但通过普通X线片排除舟状骨骨折较为困难。在舟状骨损伤的处理中，其他影像学检查方法正得到越来越多的评估。MRI已被证明在成人中具有重要价值，但在儿童中的应用研究有限。
评估MRI在儿童疑似舟状骨损伤的急性处理中的作用。
56名疑似舟状骨损伤的儿童（共57处损伤）在初次受伤后10天内接受了MRI检查。MRI结果用于指导损伤的处理。
57处损伤中有33处（58%）MRI结果正常，患者出院。16例（28%）诊断为舟状骨骨折并早期开始了适当治疗。此外，MRI还显示了腕关节周围的其他骨折和腱鞘囊肿。
儿童急性舟状骨损伤的MRI显著改变了处理方式。扫描结果正常的儿童可更早出院。舟状骨骨折能更早得到确诊，其他病理状况也能被检测出来。
