The duration of splinting after a child has a fracture must vary depending on the specific fracture site. If the fracture is of an upper extremity, such as a proximal humerus fracture or a distal radius fracture, the splint can be removed after 2-3 weeks of immobilization. For ulnar radius fractures, humerus fractures, or elbow fractures, splinting can be removed in about 3-4 weeks. If the fracture is of a lower extremity, such as a fracture of the ankle or foot, the splint can be removed in 2-3 weeks. However, if there is a fracture of the tibiofibula, it takes about 3-4 weeks to remove the splint because the bone grows relatively slowly. The longest fixation time is for femur fractures or femoral neck fractures, which require fixation for about 5-6 weeks for femur fractures and 2-3 months for femoral neck fractures.
