The carpal bones are located in the wrist joint and include eight bones. A fracture of the carpal bone is often caused by a fall or a violent injury that results in an impact on the wrist. Fractures of the carpal bones can generally be characterized by the following symptoms: first, pain, which is very obvious when the fingers are moved or when the wrist joint is moved. Second, swelling, swelling is usually due to localized bleeding after the fracture of the wrist bone, or soft tissue damage around the wrist bone leads to swelling after the fracture of the wrist bone. Third, bleeding signs of bruises and petechiae. Carpal fracture can be seen on the body surface because there is bleeding from the fracture site, resulting in petechiae and ecchymosis under the skin. Fourthly, limited wrist movement, wrist movement is obviously limited, this is due to the pain and swelling caused by the fracture of the carpal bone, the fracture of the carpal bone is sometimes more insidious, and sometimes the conventional X-ray can not be early diagnosis. If a carpal fracture is suspected, CT or MRI should be performed to further confirm the diagnosis, so as to facilitate early braking or surgical treatment.
