Application Of High-Frequency Color Doppler Ultrasound In Diagnosis Of Acute Traumatic Lesions Of Foot And Ankle

Objective: The application of high-frequency Color Doppler Ultrasound on traumatic lesions of foot and ankle was discussed with the findings of operation and results of pathology as the diagnostic gold standard.Method: 77 cases suspected foot and ankle traumatic lesions patients in Xinjiang Medical University second Affi-liated hospital outpatient or inpatient from January 2013 to September 2015 were detected by color Doppler Ultrasound and the characteristics of changing ultrasonog-ram were observed.With surgical and pathological results as the gold standard,the detection ability in traumatic soft tissue lesions of foot and ankle of high-frequ-e ncy ultrasonography was evaluated.50 cases of suspected ligaments,tendons,joint,nerves injury cases were examined by MRI at the same time,comparing the examination results of ultrasonography and MRI in traumatic soft tissue of foot and ankle injuries.21 cases of suspected fracture of foot and ankle were detected by Xray at the same time,evaluating the consistency of diagnosis of ultrasound and X-r ay in fracture cases of foot and ankle.Results: The diagnostic sensitivity,specificit-y,positive likelihood ratio,negative likelihood ratio,positive predictive value,nega-tive predictive value of high-frequency Color Doppler Ultrasound for 50 cases of t-raumatic soft tissue lesions of foot and ankle were 70.7%,77.8%,3.18,0.38,93.5%,36.8%,respectively.Compared with MRI,the examination results of ultrasound on the total soft tissue damage of foot and ankle,and on the ligaments,tendons,n-erves and joint injury showed no significant statistical difference(P>0.05).Compar-ed with X-ray,the consistency of diagnosis of ultrasound in 21 cases suspected fractures of foot and ankle,the Kappa=0.871(with excellent consistency).Conclusion: High-frequency color Doppler ultrasound has a high diagnostic value for acute traumatic lesions of foot and ankle,it provides clinicians with objective imaging diagnostic basis for the diagnosis and treatment on acute traumatic lesions of foot and ankle,which can be used as a conventional imaging examination method for posttraumatic lesions of foot and ankle.
