A-C These radiographs show the new anterior approach. (A) This radiograph shows an accurate intraarticular injection via the new anterior approach in the right shoulder. The upper red arrow indicates intraarticular contrast medium. There was no leakage in the soft tissue. The lower left red arrow indicates the sulcus was filled with contrast. The lower right red arrow shows a restricted capsule caudally, in accordance with the diagnosis of frozen shoulder.
