Fracture bone ringing when moving may be caused by fracture non-union, fracture with soft tissue contusion, fracture osteophytes and other factors. 1. Non-union of fracture: serious fracture or untimely treatment of fracture will obviously affect the healing of fracture, and after treatment without following the medical advice to take care of the fracture will lead to non-union of the fracture, which will cause abnormal activity of the fracture end and make a sound when moving. 2. Fracture with soft tissue contusion: if the fracture is accompanied by severe blunt contusion of the surrounding soft tissue, the soft tissue at the fracture will produce scar during recovery, and when the body moves, it will pull on the scar tissue and lead to abnormal noise. 3. Osteophytes at the fracture site: Osteophytes at the fracture site will cause the tendon activity to be blocked by the osteophytes and friction with the osteophytes when the body moves, which will result in a rattling sound. In order to determine the cause of bone ringing at the fracture site as soon as possible, it is recommended to go to the orthopedic department of the hospital in time for a comprehensive examination, diagnosis and treatment.
