A bone fracture is completely well is a fracture that meets the criteria for healing, i.e., exhibits no localized pain, no abnormal activity, blurred fracture lines, and no deformity in healing. Bone fracture is a form of fracture, i.e. crack fracture. This means that the continuity or integrity of the bone at the site of the fracture is interrupted, and there is a crack in the bone, but there is no obvious displacement of the bone. The fracture is completely well, that is to say, it has reached the clinical healing standard of the fracture, which is specifically manifested in the following points. 1. There is no localized compression pain or percussion pain of the fracture. 2. No abnormal activity at the fracture site. 3. The fracture line is blurred and the bone scab is continuous through the fracture line by imaging. 4. After the fracture of the upper limb is healed, it is able to lift 1kg weight for 1 minute after releasing the external fixation, and the lower limb is able to walk for 3 minutes without external force. Whether the fracture is completely healed or not needs to be evaluated by professional doctors, and patients should not evaluate themselves so as not to affect the rehabilitation effect.
