General reasons for stiffness, sinking and pain at the surgical site: 1. In the early stage, the muscle wound has not healed, and too much activity can easily lead to pain; then the collar and lumbar guard are not worn closely, and there is still local activity; 2. At 2-3 months, most of them are caused by insufficient muscle strength exercise and muscle weakness; then the spine is afraid to move, leading to stiff joints and muscles; 3. After several months or years, strain + insufficient exercise. Extremity symptom condition: the general recovery period of 12 months, the symptoms smooth down, the average improvement rate of about 70%.
