【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。

    【Abstract】 Objective To investigate the imagecharacteristic of MRI in acute traumatic lesion of triangular fibrocartilage(TFC). Methods MRIexamination was performed in 23 wrists with acute fracture of distal radius which werediagnosed by roentgenography. T1-and T2- weighted spin-echoimages were obtained. Signalintensity in TFC was evaluated. Results Distal radius fractures withinjuries of the adjacent soft tissues and TFC were present in all 23 cases. MRI of TFCwith two-site lesion was typical for acute injury. Acute TFC lesions were subcategorizedinto five types: central, ulnar, radial, radioulnar and entire of TFC lesion. Conclusions TFClesions were present in acute fracture of distal radius.MRI was of high diagnostic value.
