Whether a child’s leg fracture will leave sequelae depends on the different fracture sites and types. Generally speaking, a fracture of the full backbone, such as the femoral stem or tibiofibular stem, can be allowed to heal on its own with conservative external fixation in a cast if there is no significant displacement. If there is significant displacement, it can be healed by surgical incision and internal fixation. Generally speaking, there will be no significant sequelae, but because fractures involving the articular surface are not yet closed in children, most fractures involving the articular surface will be in the epiphysis, which may affect future growth and development.
