Within the first 3 days after surgery: 1. Elevate the injured upper limb: The nurse will use a pillow to elevate the injured upper limb, generally so that “the hand exceeds the elbow and the elbow exceeds the heart”, such a position is conducive to the swelling of the injured arm. Avoid prolonged sagging of the injured upper limb; 2. After the child’s anesthesia has subsided: after the hand can move, supervise and guide the child to do the fist-clenching and releasing action, in order to promote the swelling. The fist clenching activity can be done 4 times a day for 10 minutes each time; 3) It is good to have a light diet, as the child’s fracture heals quickly and does not need to eat food or medication that “accelerates fracture healing”. 3 days-3 weeks after surgery: The child can walk on the ground, but the cast should be fixed with a tricot to avoid falls and bumps. If the child feels comfortable with the pain and symptoms, he/she can return to school. Until the fracture is healed and the Kirschner pin is removed, care should be taken to sterilize the end of the pin. The end of the needle should be checked and disinfected approximately every 4 days. If there is significant redness and oozing at the eye of the needle, oral cephalosporin anti-inflammatory medication can be administered if necessary. 3 weeks after surgery: You will need to bring your child to the outpatient clinic for a follow-up check to see if the cast can be removed depending on how the fracture is healing. After the cast is removed, the child can do simple elbow flexion and extension exercises. 4 weeks after surgery: You will need to bring your child to the outpatient clinic for a follow-up check to see if the fracture is healing enough to remove the kyphosis pin. The removal of the pin does not require anesthesia and can be done in the outpatient dressing room with little or no pain. After the cast is removed, the child should start to do elbow flexion and extension exercises. You can use small water bottles and dumbbells to assist the exercises. 6 weeks after surgery: The child will need to return to the outpatient clinic in the near future to check the functional recovery of the elbow joint and, if necessary, to perform functional rehabilitation in the outpatient clinic. At home, you should continue to supervise your child to do active elbow exercise activities, which can be assisted by small water bottles and dumbbells. 1 year after elbow fracture surgery: Recently, you need to bring your child back to the hospital for a review to see how the fracture is healing and shaping and how the child is recovering functionally. Children’s bone development and growth are very related and may change with growth, it is very important to follow up on time.
