BACKGROUND: The treatment of chronic @entity8244 remains controversial. High rates of redislocation and complications have been reported after surgery. In our view, correction of malalignment with @entity3165 is the key to a good surgical result. METHODS: Since 1975, twenty-two @entity1 were treated surgically for chronic @entity8244 at our hospital. The procedure consisted of open reduction of a dislocated radial head followed by radial and/or @entity3165 , with or without reconstruction of the annular ligament or by reconstruction of the annular ligament alone. The ages of the @entity1 ranged from four to twenty years. In 1991, we modified the surgical technique by performing an oblique @entity3165 with angulation and elongation and rigid plate fixation. Bone-grafting at the osteotomy site was also performed if necessary. A cast was applied with the forearm in @entity717 and was worn for two to four weeks. Nine @entity1 were treated with this modified technique. RESULTS: The mean interval between the @entity130 and the reconstructive surgery was ten months. There were no serious surgical complications. Of the thirteen @entity1 treated before 1991, four had a good reduction and seven had redislocation. Seven @entity1 had restricted @entity717 postoperatively. Of the nine @entity1 treated with the modified osteotomy since 1991, seven had a good reduction. Two @entity1 , who had had slight radial @entity85 preoperatively, had subluxation postoperatively. Two @entity1 had restricted @entity717 . CONCLUSIONS: Since we modified our technique for @entity3165 , good reduction of the radial head has been achieved without causing serious @entity1159 . Both angulation and elongation of the ulna are required to allow the radial head to reduce.
