title: Technique of Kirschner wire reduction and fixation of displaced two-part valgus angulated proximal humerus fractures at the surgical neck.
abstract: This article describes the technique of closed reduction with percutaneous fixation using Kirschner wires in helping the reduction of two-part valgus angulated and displaced proximal humerus fractures at the surgical neck. Traditional open reduction may lead to more accurate anatomic reduction; however, extensive tissue dissection increases the risk of avascular necrosis. Thus, closed reduction of unstable fracture mostly required forceful reduction maneuvers, which can harm the vascular supply and increase hematoma formation. Reduction of the fractured sides can easily be performed by engaging Kirschner -wires with a joystick method and fixation can be secured by using threaded pins. Thirty-six consecutive patients with displaced, two-part, valgus-angulated proximal humerus fractures at the surgical neck were treated by this method. The patients were followed for an average of 38 months. All fractures healed. According to the Constant scoring system, 21 patients (58%) had excellent, 9 patients (25%) had good, and 6 patients (17%) had fair results. The technique of closed reduction with a joystick method and percutaneous fixation is regarded as a reasonable treatment alternative in displaced two-part valgus angulated proximal humerus fracture.
