Spinous process tenderness is common in the spinous processes of kyphosis caused by spinal tuberculosis, fractures or congenital spinal deformities. Pressing the spinous processes causes pain. This bursa is located on the spinous processes, between the supraspinous ligament and the skin, and is generally not accessible by hand. Elderly people with spinal deformities (kyphosis) who sit with their backs against a chair for a long time often suffer from friction and compression injuries, which can lead to inflammation of the supraspinous ligament bursa, causing the bursa wall to secrete synovial fluid and local swelling. Extending the neck, bending the waist, and turning around can all cause referred pain. Clinically, small or less obvious cystic masses can be touched at the site of frequent friction in the kyphosis deformity of the spine, which causes pain when pressed. Sometimes when taking an X-ray, calcification of the cyst wall can be seen on the lateral view.
