1.After the revision and fixation, the next day, 3 to 4 days, one week, two weeks and three weeks, and then can be reviewed regularly according to the time given by the doctor. 2.After external fixation of the small splint, the limb should be elevated about 30 degrees to facilitate blood return and swelling of the limb, and the affected limb can be elevated with a brace or pillow. 3. Closely observe the blood flow, sensation and motor function of the injured limb, especially within 1-4 days after revision, pay attention to the arterial pulsation, swelling degree, temperature, color sensation and active activity of the injured limb. If the swelling of the extremity is very swollen, the skin is cold, there is purple or pale after, the skin sensation is reduced and other symptoms, should promptly release the external fixation and come to the hospital for review, to prevent the occurrence of ischemic contracture and other complications of the limb. 4. Pay attention to the presence or absence of fixed pain points. If there is fixed pain outside the splint fixation of the limb or at the ends of the small splint, the splint should be removed promptly for examination to avoid pressure ulcers or nerve and vascular injury. 5.Adjust the tightness at any time. Fracture trauma plus reset secondary injury, swelling of the limb within 1-4 days of reset is obvious, and there is a tendency of pressure rising within the splint, the cloth belt should be relaxed appropriately every day, and as the swelling subsides afterwards, the cloth belt should be tightened appropriately again every day, but it is still appropriate to be able to go up and down 1cm. 6. Attention should be paid to the warmth of the injured limb in the cold season. In the hot season, attention should be paid to ventilation, to keep the splint and cast clean, by which children should avoid pollution such as wet urine and wet stool. 7, in the physician patient appropriate functional exercise to accelerate the swelling subsidence and promote fracture healing. (1) Once the fracture is repositioned and fixed, you can start muscle isometric contraction exercise and move your fingers and toes. (2) After 1-2 weeks, wrist, elbow, ankle and knee extension and flexion activities can be performed. (3) In the 3rd week, increase the activities of shoulder and posterior hip joint. (4)After 4-6 weeks, the joint movement can be increased, and the lower limb fracture can be walked down with crutches, but not weight bearing. (5) At week 10, the splint is removed for trial activities, and the fracture of the lower limb can be walked on the ground with an abductor, and weight-bearing is gradually practiced. (6) At 10-12 weeks, the fracture is in bony healing, and the patient can do light work and abandon the crutches for walking. (7) It is especially important to point out that patients with plate fixation should never remove the cast on their own without the doctor’s permission, have and get out of bed with the cast, and after the cast is removed, they should not get out of bed without the hospital’s permission (because the plate cannot support the limb), so as not to break the plate and cause unnecessary pain.
