Bone fracture is more serious than bone contusion. Bone fracture is actually a kind of fracture, while bone contusion refers to subcortical bone marrow hematoma, bleeding, and fracture of bone trabeculae. Bone fracture is more serious than bone contusion in terms of the degree of injury, clinical symptoms and recovery time. 1. Degree of injury: Bone fracture belongs to the fracture of bone, most of bone contusion does not have bone fracture, so the degree of damage to the bone fracture is more serious, and the degree of pain of bone fracture is also heavier than bone contusion. 2. Clinical symptoms: most of the patients with bone fracture have more pressure and swelling pain than bone contusion, and bone fracture also affects their normal activities or weight bearing. 3. Recovery time: The recovery time of most bone fractures is longer than that of bone contusion, and it takes six to eight weeks to recover from a bone fracture in general, while most bone contusions can be moved in an orderly manner after three to four weeks after strict braking and systematic treatment. Bone fracture and contusion are different concepts, with different degrees of injury, but need to be combined with imaging to confirm the diagnosis, so for this type of trauma factors, objective imaging is also very important.
