Radial neck osteolysis after annular ligament reconstruction. A case report.

The treatment of the dislocated radial head in a late Monteggia lesion remains a matter of controversy. Annular ligament reconstruction using a strip of triceps tendon is a commonly used technique. Although most published series report good and excellent results, the overall complication rate of this procedure is not known. This study reports a 9-year-old boy who had avascular necrosis and bone resorption of the radial neck after a late annular ligament reconstruction using a sling of triceps tendon for a radial head dislocation that was not detected previously.
