68 pediatric patients with displaced supracondylar humeral fractures were randomized to one of two methods of closed reduction. In one group, if closed manipulation did not yield acceptable reduction, the joystick technique was used to facilitate reduction. In the other group, only manual traction was used for reduction. Once reduction was achieved, all patients received fracture fixation with percutaneous pinning. Results demonstrated a significantly shorter operative time, shorter fluoroscopy time, and higher reduction success rate in the joystick group compared to the manual traction group. The time to union, final radiographic outcome, and the clinical outcome did not significantly differ between groups.
