The sequelae of patients after recovering from trauma, in general, have the following symptoms: First, it may be accompanied by dysfunction of the affected limb, which may be caused by the patient’s injury to the muscles or tendons of the limb during the trauma, in which case the limb will have dysfunction, such as flexion function, if it is not repaired or strengthened in a timely and effective manner. Secondly, numbness may appear in the distal part of the limb after the trauma. In this case, it is also due to the damage to the local nerve during the trauma, which will lead to the numbness of the distal part of the limb later. Thirdly, local dysfunction may be caused by local scar formation after trauma, and local muscle or skin adhesion together, which will cause local dysfunction. Therefore, after the trauma, we must go to the hospital for detailed examination, and if it is clear that there are side injuries in the trauma and trauma, we must carry out surgery to repair these side injuries in time to avoid affecting the function of the limbs in the later stage. And avoid infection when recovering from trauma, so as to effectively alleviate the scar growth, which will lead to dysfunction in the later stage.
