To determine a dorsal hand fracture, you can judge from the following aspects: 1. the back of the hand appears deformed, different from the normal back of the hand, or there is no obvious deformity, but the fingers grasp differently from the normal hand. 2. pain and swelling are felt, or the sound of bones breaking off and rubbing can be heard. 3. x-rays and CT are used to determine the site, type, and severity of the fracture and fracture, and the first two can be used to roughly determine whether the dorsal hand fracture is present. For dorsal hand fractures where the symptoms and signs are not very obvious, it is also likely to be impossible to determine, so when a dorsal hand fracture is suspected it is best to take a film for analysis. A fracture of the back of the hand is usually referred to as a metacarpal fracture. In the case of a metacarpal fracture without significant displacement or simple angular displacement, most cases are treated conservatively with manual repositioning and immobilization in a cast or splint for about 5-6 weeks. A diet rich in calcium is recommended to help promote bone growth and healing.
