During the period of December 2012 to July 2013, 30 children with displaced supracondylar fractures of humerus were treated by closed reduction and percutaneous crisis-cross K-wire fixation. The technical details of the procedure include. (1) reduction under general anaesthesia with adequate relaxation. (2) insertion of crossed K-wire under image intensifier control to determine adequacy of reduction. By Mitchell and Adam's criteria acceptable results were obtained in 28 out of thirty cases studied. Two results were unacceptable because of loss of flexion of 30°and 20° respectively; moreover one of these patients developed postoperative ulnar nerve injury also. There were two cases who presented with absent radial pulse both of them recovered after emergency reduction and pinning without long term sequel. This is a safe and reliable technique for obtaining and maintaining an excellent reduction in this difficult fracture.
