The ligament connecting the adjacent spinous processes is the supraspinous ligament. When inflammation of the supraspinous ligament occurs, it can cause lumbar pain and back pain, and the symptoms are aggravated when bending over, and can be alleviated after lumbar back extension or bed rest. The pressure point is located in the spinous process or two adjacent spinous processes, superficial, and limited to the top of the spinous process. Occasionally, the supraspinous ligament that can slide to both sides of the spinous process can be touched, which is called the supraspinous ligament peeling phenomenon, and there is no abnormality on X-ray. Treatment includes maintaining a good sitting and standing posture, preventing long-term bending work, advocating lumbar activities between work, and strengthening muscle strength training, especially lumbar back muscle exercise, which has a certain effect on the prevention of the disease and the treatment of patients with mild cases. Oral non-steroidal analgesic drugs, such as indomethacin, diclofenac, etc., and local closed injection treatment can be carried out when the pain is severe.
