Finger fractures are determined by first having a history of injury to the finger and by observing the swelling, pain, and functional limitations of the injured area, and of course, the most accurate method is to perform an x-ray. After the injury, the patient will have obvious pain in the finger, swelling, bruising and pressure pain. The most typical and definite diagnosis of a fracture is a functional limitation of the finger, which means that the bending and straightening of the finger is significantly restricted. For patients with finger injuries, a high degree of attention should be paid to finger fractures. Therefore, if a patient is suspected of having a finger fracture, the most definitive method is to perform an imaging examination of the finger area. If a fracture occurs, the fracture should be actively treated, first of all by examination, and according to the degree of injury and the type of fracture, the most effective treatment should be developed, such as external fixation and, if necessary, internal fixation, such as the use of steel nails for internal fixation, etc. It is important to pay great attention to the complications after the treatment of the finger fracture, such as wound infection, muscle tendon and nerve The complications of finger fracture management, such as wound infection, muscle tendon and nerve damage, should be highly noted.
