Abstract:[Objective] To introduce the surgical technique and preliminary clinical results of a new combined reduction frame for su- pracondylar fractures of the humerus in children. [Methods] A retrospective study was made on 30 children who received closed reduction under the new combined reduction frame and percutaneous internal fixation with Kirschner wire for humeral supracondylar fractures. The patients were placed in the lateral decubitus position with the affected limb and body rested on the new combined reduction frame that at- tached with the operating table to resist the traction force in the opposite direction. After manual reduction of the fracture, its position was temporarily maintained by the forearm weight in suspension with elbow flexion at 90 degrees. As a satisfactory reduction was checked by fluoroscopy, Kirschner wires were percutaneously placed in a cross manner to fix the fracture stably. [Results] All the patients got operation conducted smoothly without complications such as nerve injury, whereas with operation time of (28.0±3.7) min, fluoroscopy of (4.5±0.9) times, intraoperative blood loss of (23.5±6.9) ml and hospital stay of (3.5±0.9) days. A month after operation, all the children got complete fracture healing with excellent and good rate of 98.7% based on Flynn score, and had the implant removed. [Conclusion] Utilizing this new combine reduction frame, fracture reduction and internal fixation do be realized by single-person operation for humeral supracondylar frac- tures in children, which reduces the need for medical staff, declines radiation exposure, shorten the operation time and save cost of patients.
