Pediatric bone metabolism is faster and blood supply is richer, so fracture healing is also faster and easier to repair than adults. The healing time of pediatric fracture is as follows: 1, age classification: children aged 0-2 years old need about 4 weeks to heal, while children aged 3-8 years old need about 6 weeks, and children aged 9-14 years old can be healed in about 8 weeks; 2, fracture type: fresh, stable fracture needs about 6 weeks to heal after successful reset; unstable fracture such as comminuted and spiral need a long time, about 8 weeks. Open fractures that are more than half a month old and then dislocated need to be treated surgically, and postoperative recovery takes about 10 weeks, and postoperative recovery for children with non-connected fractures takes even longer. The healing time for fractures is only approximate and may vary according to individual differences, so it is important to have regular radiographs and not to remove the fixation at will to avoid problems.
