Roughness of the bone cortex is seen in relatively minor bone injuries and is a sign of minor damage to the trabeculae and periosteum of the local bone cortex. Most recovery time is relatively short, usually 3-4 weeks after the injury. Some patients can recover by local immobilization such as plaster or brace, and some patients can recover by braking. However, for children and adolescents, the recovery time is about 2 weeks because of the good recovery ability during the growth period. For the elderly, malnourished patients or patients with underlying diseases such as liver disease and kidney disease, the recovery time is relatively delayed because the recovery ability is significantly worse than normal, requiring 4-6 weeks to recover or even longer. Recovery is aided by the use of blood-boosting and bone-building drugs, such as oral red pill tablets and wound-joint tablets, while regular review tablets are needed to understand the healing situation.
