Fig. 5. A 6-year-old boy presented 6 months after injury of his left elbow with pain and an extension deficit. (A) Radiograph shows anterior dislocation of the radial head with calcification of annular ligament remnants. (B) He was treated with open reduction and ulnar osteotomy, because the radial head was unstable with open reduction alone. (C) Radiograph obtained 2 years later showing an anatomical position of the radial head.
