Sequelae of trauma generally include limb dysfunction, distal limb numbness, local dysfunction and so on. 1. If the muscle or tendon of the limb is damaged during the trauma and not repaired in time, it may cause dysfunction of the limb. 2. If the nerve is damaged during the trauma, numbness at the distal end of the limb may occur. 3. Localized scars formed after trauma, resulting in muscle and skin adhesion together, in which case local dysfunction may occur. It is recommended to go to the hospital for a comprehensive examination after the trauma, and timely surgical repair of traumatic injury to reduce the chances of limb dysfunction and the risk of infection, and effectively alleviate the scar proliferation.
