When the damage is mild, only part of the periosteum is torn or damaged, giving local physical therapy and hot compresses, oral anti-inflammatory and analgesic drugs and drugs to activate blood stasis can speed up the local blood circulation, promote the supply of local nutrients to speed up the recovery of the periosteum, and can even be repaired in a week. Periosteal injury is mostly seen in car accidents, falling injuries, which leads to the local periosteum of the injured area to produce stimulation and blood flow changes. It can also be caused by periosteal stripping during fracture reduction surgery.
