摘　　要：目的利用ＭＲＩ技术，探讨创伤性三角软骨（ＴＦＣ）损伤急性期的特征，为早期治疗提供依据。方法选择２３例急诊经Ｘ线片确诊为桡骨远端骨折者进行磁共振成像（ＭＲＩ）检查。Ｔ１和Ｔ２Ｗ１应用ＳＥ序列，对ＴＦＣ的信号密度进行评价。结果２３例桡骨远端骨折均同时存在腕部软组织损伤和ＴＦＣ损伤。ＴＦＣ两处损伤是急性期的典型改变。急性期ＴＦＣ损伤可涉及五个部分即中心、尺侧、桡侧、尺桡侧和整体损伤。结论桡骨远端骨折的同时也存在腕部ＴＦＣ的损伤。Objective To investigate the image characteristic of MRI in acute traumatic lesion of triangular fibrocartilage(TFC). Methods MRI examination was performed in 23 wrists with acute fracture of distal radius which were diagnosed by roentgenography. T1 and T2 weighted spin echoimages were obtained. Signal intensity in TFC was evaluated. Results Distal radius fractures with injuries of the adjacent soft tissues and TFC were present in all 23 cases. MRI of TFC with two site lesion was typical for acute injury. Acute TFC lesions were subcategorized into five types: central, ulnar, radial, radioulnar and entire of TFC lesion. Conclusions TFC lesions were present in acute fracture of distal radius.MRI was of high diagnostic value.
