Objective To review the research progress in the repair and reconstruction of isolated traumatic radial head dislocation with annular l igament injury in children. Methods In recent years, the related l iterature concering isolated traumatic radial head dislocation with annular l igament injury in children was reviewed. Results For isolated traumatic radial head dislocation with annular l igament injury in children, the surgery should be chosen as the main treatment, includingopen reduction and annular l igament reconstruction surgery. Triceps aponeurosis is usually used as reconstruction materials of annular l igament, mainly because the position of taking material of annular l igament is at the operative incision with less surgery trauma and short operative time; aponeurosis is tough and thick with rigid fixation and low risk of re-dislocation. Artificial materials are paid attention to increasingly because they are easy to get, have rigid fixation, and can avoid operative injury caused by taking material of annular l igament. Conclusion Currently active annular l igament reconstruction surgery should be taken; triceps aponeurosis is widely adopted as reconstruction materials of annular l igament and artificial materials have come to be a new research trend.
