The method of determining whether the hand bone is fractured is as follows: 1. First, we must confirm whether there is any trauma here, and injury is a necessary condition for the existence of a fracture. 2. To determine whether there are signs and symptoms associated with a fracture here, for example, we must first see whether there is any pressure pain or percussion pain here. By percussion pain, we mean that the injured part is tapped gently with the finger or tapped on the adjacent part of the injured part to see if there is any particular pain in the injured part through vibration transmission, and if there is, it suggests that there may be a fracture. It is also important to see if there is any significant swelling or deformity, which can be detected by comparison with the contralateral hand. On top of this, it is important to look for any abnormal movement or bone rubbing sensation. If the patient has the above symptoms and history, he/she should go to the orthopedic department as soon as possible and ask the doctor to make relevant examinations and do plain films to clarify whether there is a fracture.
