Eighty-two cases of supracondylar fracture of the humerus in children were followed-up from 1 to 13 years with an average length of 4 years and 5 months. Supracondylar fractures were classified by Holmberg's classification. They were treated by fixation with plaster cast, plaster cast after manipulation, traction, percutaneous pinning or open reduction. We studied about the range of motion (R. O. M.) and varus or valgus deformity of the elbow after the treatment. There were no relation between the R. O. M. and deformity of the elbow and the degree of displacement of distal fragment after the treatment. The deformity and abnormal R. O. M. of the elbow were essentially caused by incomplete reduction. Decrease of the tilting angle led to the limitation of flexion of the elbow. If the conservative treatment is not acceptable to get the good augment, open reduction must be considered.
