From 1980 to 1992, 62 cases of Monteggias fracture in children were treated byoperation, in which were 18 cases were fresh, 44 old. The following procedure performed separately: the reduction of the head of radius; the use of internal fixation following anatomical reduction of the ulna or the osteotomy of the ulna and elongation; the repair or reconstruction of annular ligament of the superior radioular joint. From the last follwup, 93 percent was excellent in the clinical result. The operative method was introduced briefly. The importance of earlydiagnosis and prompt effective treatment of Monteggias fracture in children was discussed. The key to prevent redislocation of the head of radius was that rigid fixation of ulna and repair or reconstruction of the annular ligament of radius were important. It is also important to improve curative effect that early functional movement after operation was mandatory for good operative results.
