A baby’s finger being pinched can be determined by its symptoms, the presence of fracture-specific signs, and related examinations to determine whether it is fractured or not. 1. Symptoms: Finger fracture may cause pain, swelling and dysfunction of the finger, but it is easy to be confused with soft tissue injury of the finger. 2. Signs of fracture: Finger fracture may show signs of fracture, including deformity, abnormal movement, bone rubbing sound or bone rubbing sensation, etc. If the above signs exist, it is possible to determine whether the finger is fractured. If these signs are present, a fracture can be recognized. 3. Related examination: Imaging examination can clarify whether there is a fracture or not, which is more accurate. Commonly used tests include X-ray and CT. If your baby’s finger is pinched, it is recommended that you seek prompt medical attention and have the relevant tests performed to clarify the diagnosis and then proceed to diagnosis and treatment.
