Minor fractures are usually incomplete fractures or fractures without displacement, such as bruise fractures, which can usually recover on their own but do require fixation. Minor fractures usually have no displacement of the fracture end or joint movement disorders, and the body can form bone scabs on its own, which will gradually heal. Immobilization is usually sufficient after the fracture, with the affected limb being immobilized in a cast or brace for 4-6 weeks. After regular conservative treatment, the fracture will gradually recover. Immobilization is a necessary step, as failure to immobilize the fracture may result in slight movement of the fracture end with daily activities, resulting in non-union or abnormal healing of the fracture. Therefore, it is important to treat the fracture as prescribed by the doctor, regardless of the severity. During the recovery period of the fracture, care should be taken to avoid putting the affected limb under stress, such as not lifting heavy objects for upper limb fractures, while the affected limb can be elevated to promote venous return to reduce swelling. The patient should closely observe the blood circulation of the injured limb during the cast. If the cast is too tight and causes obstruction of blood flow to the limb, resulting in pain and darkening of the limb, the patient should go to the hospital in time to loosen the cast and refix it.
