Metacarpal fractures

　　Metacarpal fractures are mostly caused by direct violence. Metacarpal fractures are superficial, and in addition to obvious pain, swelling, tenderness, and limited activity, there is obvious deformity. For suspected fractures, an X-ray film can be taken for diagnosis.

　　Metacarpal fractures are superficial, and in addition to obvious pain, swelling, tenderness, and limited activity, there is obvious deformity. For suspected fractures, an X-ray film can be taken for diagnosis. The treatment of metacarpal fractures is often not given enough attention, often resulting in malunion or non-union due to poor alignment or unstable fixation, and often leading to contracture of the joint capsule and collateral ligaments due to improper fixation or excessive fixation time, resulting in joint stiffness; especially fractures near or through the joint often lead to joint ankylosis, seriously affecting the function of the fingers.

　　Based on the medical history, clinical manifestations, and X-ray examination, diagnosis can be made.

　　1. In daily life, be aware of the possibility of unexpected events and make full use of the tools around you to reduce the risk of injury caused by accidents.
　　2. Once a disease occurs, treat it actively to strive for the best treatment effect. Timely and effective treatment of complications is needed to minimize disability and improve the quality of life of patients.
　　Three actively carry out functional exercises under the guidance of the doctor to prevent the occurrence of complications.

　　1. Comprehensive physical examination:Pay attention to shock, soft tissue injury, bleeding, and check the size, shape, depth, and contamination of the wound. Check for exposure of bone ends, and for nerve, blood vessel, or other injuries.

　　2. X-ray Examination:In addition to anteroposterior and lateral X-ray films, special position films should also be taken according to the condition of injury, such as occlusal position, dynamic lateral position, axial position, and tangential position, etc. X-ray films can accurately show the degree of injury and the type of fracture.

　　1. What foods are good for finger fractures

　　(1) It is advisable to eat more vegetables rich in fiber, and eat bananas, honey, and other foods that promote gastrointestinal digestion and defecation.

　　(2) In the early stage, one should eat foods that promote blood circulation, remove blood stasis, and dissipate qi, such as vegetables, soy products, fish soup, eggs, etc.

　　(3) In the middle stage, one can eat foods that help relieve pain, remove blood stasis, regenerate new tissues, and promote bone healing and ligament repair, such as bone soup, Cordyceps chicken, animal liver, etc.

　　(4) In the later stage, one can eat more foods that benefit the liver and kidneys, invigorate the qi and nourish the blood, and relax the tendons and collaterals, which can help the formation of callus, such as chicken soup with old hen, pork bone soup, sheep bone soup, etc.

　　2. What foods should be avoided for finger fractures

　　(1) Avoid blindly supplementing calcium.

　　(2) Avoid indigestible foods.

　　(3) Avoid eating too much meat and drinking braised bones.

　　I. Treatment Methods

　　1. For fractures without displacement, the injured finger can be fixed in a flexed position of the metacarpophalangeal joint and a slightly flexed position of the interphalangeal joint with an aluminum plate or plaster. The fixation should be removed for about 4 weeks, and functional exercise should be performed. For comminuted fractures of the distal phalanx, they can be treated as soft tissue injuries and do not need to be fixed.

　　2. For closed fractures with displacement, manual reduction and external fixation can be performed. The position of fixation should be determined according to the situation of fracture displacement, such as fixing the fingers in a flexed position for those with palmar angulation; for avulsion fractures at the base of the distal phalanx, the proximal interphalangeal joint should be flexed and the distal interphalangeal joint should be extended to fix, and the fixation should be removed after 4 to 6 weeks.

　　3. For patients with open fractures and closed fractures with poor reduction after reduction, open reduction and internal fixation should be performed. There are many methods of fixation, which are determined according to specific circumstances. The commonly used method is Kirschner wire fixation, but it should be based on the principle of firm and reliable, while avulsion fractures at the base of the phalanx are often treated with tension band fixation, and phalanx fractures can also be fixed with screws.

　　II. Prognosis

　　Generally, the prognosis is good.
