The length of time taken for healing depends on where the fracture is and how severe the break is. For example, a simple buckle fracture will need a plaster cast for 2 to 3 weeks and be almost completely healed in 4 weeks.Children heal in about half the time it takes an adult to heal from a similar injury.or example, a simple buckle fracture will need a plaster cast for 2 to 3 weeks and be almost completely healed in 4 weeks.
