Abstract: 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=0.706).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.
