A growth plate fracture affects the layer of growing tissue near the ends of a child's bones. Growth plates are the softest and weakest sections of the skeleton — sometimes even weaker than surrounding ligaments and tendons. An injury that might cause a joint sprain for an adult can cause a growth plate fracture in a child.
Growth plate fractures often need immediate treatment because they can affect how the bone will grow. An improperly treated growth plate fracture could result in a fractured bone ending up more crooked or shorter than its opposite limb. With proper treatment, most growth plate fractures heal without complications.
