Hand is an important organ for human beings to carry out daily life and engage in production and labor, and its functions include movement, sensation, expression, etc. In life, we have to use our hands all the time, and our hands are more exposed than other parts of the body in life and labor, so the incidence of hand trauma is also higher than that of other parts of the body. Hand injuries can cause different degrees of dysfunction, affecting daily life and work. Hand trauma is a common trauma, accounting for more than 1/3 of the total number of traumas. There are many causes of hand trauma and more types of trauma, but for the general public, hand trauma can be categorized into open and closed injuries. Open injuries are often combined with bleeding, pain, swelling, deformity or dysfunction. Closed injuries, because the skin is intact and the subcutaneous tissues are severely swollen after the injury, tend to cause the skin to tighten the swollen soft tissues, making the local blood circulation impaired, and some patients may even lead to necrosis of the distal limb or soft tissues as a result. There are obvious age and gender differences in the occurrence of hand trauma, especially the highest incidence in the age group of 20-30 years old, and there are far more males than females. Hand trauma is most common among machine builders, carpenters, construction workers and farmers, mainly related to the labor intensity of these types of work, requiring a high degree of technical proficiency, poor safety protection measures and more opportunities for injury. Secondly, there are life injuries, violent fight injuries, traffic accident injuries and sports injuries. Compared with the whole body trauma, although hand trauma leads to less life-threatening possibility, but the disability caused by severe hand trauma, significantly reduce the human ability to work, not only will affect the patient’s life and work, to the patient and the family to bring great pain, but also to the unit and the community to cause great economic losses. Once the hand trauma, we should do what is possible to keep a pair of intact hands? The key is to do “three early”, that is, early diagnosis, early treatment, early recovery. 1, early diagnosis for the occurrence of hand trauma to the hospital emergency treatment patients, the doctor should first of all in a short period of time on the patient trauma to understand the situation, to find out whether accompanied by bone and joints, tendons, nerves or blood vessels damage. For patients with suspected osteoarthritic injuries, all injured fingers must be photographed from multiple angles, including standard lateral and oblique views. All fractures or dislocations of the first metacarpal require a hand surgery consultation, as the thumb is of particular importance in hand movement. 2. Early treatment For open injuries (e.g., superficial puncture wounds, contusions, cuts, etc.) that are generally small and not serious, a simple antiseptic bandage can be given. For severe bleeding, intravenous access can be established quickly to replenish blood volume according to the patient’s bleeding and vital signs. For injuries to tendons, nerves and bones, it is necessary to make a correct diagnosis and fully estimate the consequences before surgery, and decide the treatment methods and steps in time. 3.Early rehabilitation Hand trauma patients need to stay in the hospital for one to two weeks after surgery as observation and early rehabilitation stage, the earlier the hand rehabilitation, the better the effect, because postoperative edema, pain and joint stiffness will affect the patient’s future recovery of hand function if they are not dealt with in a timely manner. Early rehabilitation usually involves the participation of hand surgeons, occupational therapists and physiotherapists, which is conducive to strengthening the communication among different specialties and making the most appropriate rehabilitation plan for the patient.
