The fixation skills of pediatric tibia shaft fractures. A The sequence of placement of half-pins in turn at the nearest (1), farthest (2), and close to the fracture (3, 4). B The selection of the position followed the “near-near, far-far principle,” and 4 half-pins were inserted from the inner surface of the tibia perpendicular to the bone surface. The outside fixator needed 2 half-pins. C The proximal end was located below the level of tibia tubercle, and the distal end was driven through the fibula into the tibia
