Bone cortical roughness is a relatively minor bone injury, only a minor injury to the local bone trabeculae and periosteum of the bone cortex, recovery time is relatively fast, and can be recovered in 3-4 weeks after the injury. However, in children, because they are in the growth period, they have good recovery ability and can return to normal in about 2 weeks. For the elderly, malnourished patients or patients with underlying diseases, such as common liver disease and kidney disease, the recovery ability will be significantly lower than normal, and the recovery time will be relatively delayed, taking 4-6 weeks to recover, or even longer. For special parts of the bone cortical irritability recovery time will also be longer, such as the rib area, because the thorax is always in activity when breathing, the damaged ribs do not get a good brake, so the recovery is slower, also need about 4-6 weeks. During the recovery period, it is necessary to apply the necessary brakes and use blood-stasis and bone-building drugs to help recovery, such as oral red pills.
