Ribs appear fracture, the use of chest strap for external fixation, must be fixed for about 4-6 weeks. Generally 4 weeks after the fracture must be reviewed photos, if you see the fracture line is blurred, or even there is a bone scab growth, local pressure pain is not very obvious, and there is no pain in the activities, then you can remove the chest strap, and you can do the activities of the functional exercise appropriately. However, if the fracture is still relatively clear in the review photo, it is still necessary to continue to immobilize for about 2 weeks and then review the photo. If it is a child, the chest belt can be removed relatively early, usually 3-4 weeks can be removed. However, in the case of middle-aged and elderly people, especially osteoporotic patients, due to the relatively slow growth rate of the fracture, it must be removed in about 6-8 weeks.
