The performance of healing after internal fixation of femoral neck fracture mainly includes clinical symptoms such as disappearance of pain at the fracture site, no discomfort in weight-bearing movement, etc., as well as imaging tests. 1. Clinical symptoms: the skin color of the incision returns to normal, no pain at the fracture site, no obvious pain under hip joint adduction, abduction, extension and flexion, and no percussion pain; no obvious discomfort after full weight-bearing, all of the above can indicate that the fracture site is basically healed. Generally, it takes more than 3 months for femoral neck fracture to heal after internal fixation. 2. Imaging performance: Imaging is the gold standard of fracture healing, and X-ray examination of the hip joint is routinely chosen for judgment. X-ray shows that the fracture line is blurred or disappeared, visible bone trabeculae pass through the fracture segment, the surrounding bone scabs are formed, and the internal fixation is well aligned, etc., which can suggest that the fracture of the neck of the femur has reached the clinical standard of healing.
