Isolated Traumatic Radial Head Anterior Dislocation Treated with Open Reduction in Children / 대한정형외과학회잡지

Isolated traumatic radial head anterior dislocation without associated injuries is uncommon in pediatric patients. If diagnosed on time, most cases can be reduced by closed reduction. In some cases, the radial head was found to be trapped between annular ligament, anterior joint capsule and a buttonhole tear of the brachialis muscle, preventing closed reduction. This is a very uncommon injury and the diagnosis can be overlooked. We report a case of a 7-year-old girl who sustained an irreducible isolated dislocation of the radial head which was reduced with open reduction.
