Application value of elbow arthrography in the treatment of chronic radial head dislocation in children

Elbow arthrography serves as a valuable adjunct for differentiating between congenital and traumatic radial head dislocations, thereby informing both surgical strategy and the decision for supplemental fixation. When stable bony alignment is achieved, proximal ulnar osteotomy without annular ligament reconstruction represents an effective management strategy for chronic radial head dislocation in children.
