Abstract:
Objective To investigate the diagnostic value of ultrasonography in radial head subluxation (RHS).Methods The clinical data and ultrasonographic findings of 34 children with RHS were retrospectively analyzed.All patients were routinely treated by bilateral compared and multi-sectional elbow joints ultrasonography.And the X ray results were negative.Results Ultrasonographic manifestations of RHS included increased radiocapitellar distance in 29 cases (29/34,85.29％);widened joint space and enhanced echo in 25 cases (25/34,73.53％);hook sign,supinator muscle above the radial head in 32 cases (32/34,94.12 ％);annular ligament entrapment in 33 cases (33/34,97.06％).Conclusion Ultra sonographic manifestations of RHS have certain characteristics.Comparation of bilateral elbow joints and the application of continuous scanning ultrasound are helpful to make a quick and accurate diagnosis of X-ray negative RHS.
