Fracture healing criteria

Fracture healing criteria include local tenderness and longitudinal percussion pain, local no abnormal activity, X-ray shows that the fracture line blurred, after removal of external fixation limb function recovery, etc. 1. Local tenderness and longitudinal percussion pain This means that the fracture has been stable, no longer obvious activity and pain, indicating that the fracture is healing well. 2. No abnormal local movement, i.e. no abnormal movement at the fracture site, indicating that the fracture end has been initially connected and has a certain stability. 3. X-ray shows that the fracture line is blurred and there is a continuous callus passing through the fracture line. The progress of fracture healing can be seen visually by X-ray examination. The blurred fracture line indicates the formation and growth of callus. The appearance of continuous callus indicates that fracture healing is progressing in an orderly manner. 4. After removing the external fixator, the limb function recovered. The upper limb could lift 1 kg forward for 1 minute, and the lower limb could walk continuously for 3 minutes without crutches, and no less than 30 steps. The fracture was not deformed for 2 weeks. This reflects the recovery of limb function, can bear a certain load and maintain stability, further confirmed that fracture healing has reached a certain degree, with the corresponding mechanical strength. It should be noted that the healing time and standard of different parts and types of fractures may be different. When evaluating fracture healing, various factors should be comprehensively considered, and if necessary, comprehensive judgment should be made in combination with clinical symptoms, signs and other imaging examinations.
