Abstract:
Objective To explore the application of high frequency ultrasonography in the rapid diagnosis of irreducible radial head subluxation in children.Methods Twenty-three patients aged 1 to 5 with unilateral radial head subluxation in children were observed by high-frequency ultrasonography and radiography,and then compared the symptomatic to the contralateral side.Results No case of radial head subluxation was found by radiography.23 cases of radial head subluxation were found by high frequency ultrasonography,10 cases with articular cavity effusion.On the diagnosis of radial head subluxation in children,the sensitivity of high frequency ultrasonography was obviously higher than that of radiography.Conclusions The sensitivity of high frequency ultrasonography in the rapid diagnosis of the radial head subluxation in children is obviously higher than that of X ray film.High frequency ultrasonography through continuous scan can determine the continuity of anatomical structure and the relationship between some views to show the location of the specific structure relations.Specifically,it can be quickly and clearly diagnosed on anterior long-axis view and the lateral coronal view of radiohumeral joint.
