The term “green branch fracture” refers to fractures in children, describing a fracture in a child as being like a green branch of a plant, which breaks but does not break. Children’s bones have a thicker periosteum than those of adults, which provides good elasticity and flexibility. When subjected to external forces similar to those of adults, the fracture may be incomplete, showing only localized distortion of the bone cortex and trabeculae without a fracture line, or only causing the bone cortex to be depressed, elevated, or crumpled. Greenstick fractures are generally stable fractures and usually do not require surgical treatment. If there is obvious deformity, it can be manipulated and repositioned, and then immobilized with a plaster or a brace. During the recovery period, dietary attention should be paid to strengthening nutrition, and rehabilitation exercises are also needed, which is conducive to recovery. After the injury, if children have limb pain and activity limitation, they should go to the hospital in time for further examination and treatment.
