We had experiences of operative cases of lateral condyle fracture of the humerus in children during the past 13 years. Our series consisted of 38 patients, in which 29 cases were boys and 9 were girls. Their ages ranged from 2 years to 11 years with the average of 6.1 years old. The fracture type was subdivided according to the Wadsworth (type I: 3 cases, type II: 12 cases, type III: 18 cases, unknown: 5 cases.). The Kirschner wire and/or Fencing nail (Pro. Yamoto's special divice) were used as the fixation materials.
The satisfactory results were obtained in our all cases without any complications such as varus or valgus deformity, ulnar nerve irritation and the pseudarthrosis at the time of follow-up.
