The flexion type, supracondylar fracture of the humerus is a rare injury of the elbow in children. It is known as difficult fracture to achieve and maintain reduction and is associated with relative high incidence of complications such as ulnar nerve injury, varus deformity and limited range of motion of the elbow. We have experienced 6 cases of flexion type sapracondylar fracture of the humerus in children. We performed closed reduction and percutaneous piniiing in type II fracture and in type III fracture, open reduction and internal fixation was performed because closed reduction was failed. The resuli were generally excellent. Full range of motion of the elbow and under 5 degree varus or valgus deformity resulted in. We become to believe that the aggressive approaches-even open reduction in type III fracture-provide good results and decrease the complications mentioned previously.
