摘　　要：目的探讨腕关节三角纤维软骨复合体(TFCC)损伤的高频超声表现及诊断价值。方法回顾性分析具有完整术前MRI及超声检查资料,且经手术证实为单侧TFCC损伤的32例患者的超声表现,对比超声与MRI诊断结果。结果TFCC损伤超声主要表现为TFCC形态肿胀、结构紊乱、回声不均匀,破损处为不规则无回声区;CDFI于损伤的TFCC内部撕裂口边缘可探及血流信号。32例TFCC损伤患者中,超声诊断26例,检出率81.25%(26/32),MRI诊断27例,检出率84.38%(27/32),2种检查方法对TFCC损伤检出率的差异无统计学意义(~χ2=0.143,P=0.706)。结论通过高频超声可较准确地诊断TFCC损伤,从而简便、快速地为临床治疗提供影像学依据。Objective To discuss the ultrasonic features and diagnostic value of high frequency ultrasound in the diagnosis of the injury of triangular fibrous cartilage complex （TFCC） of wrist joint. Methods The ultrasonic features of 32 patients with pathology confirmed unilateral TFCC injury were retrospectively analyzed. The preoperative MRI and ultrasound data were complete. The difference between the two methods in diagnosis of TFCC injury were contrasted. Results The major ultrasonic features of the injure of TFCC included form swelled, structures disorganized, inhomogeneous echoes, irregular echoless in damaged place. The flow signals could be displayed from the tear opening edge of the injured TFCC by CDFI. Among 32 cases of TFCC injury, there were 26 cases （26/32, 81.25%） diagnosed by ultrasound and 27 cases （27/32, 84.38%） diagnosed by MRI. There was no significant difference in the detection rate of the two methods for TFCC injury （X2 =0. 143, P=O. 706）. Conclusion High frequency ultrasound can be used to diagnose the injury of TFCC accurately, and can provide imaging evidence simply and rapidly for clinical therapy.
