Ankylosing spondylitis can be corrected by orthopedic surgery. 1. Ankylosing spondylitis with a hunchback, i.e., a backward convexity of the spine, affects the patient’s ability to see and lie down, thus reducing the quality of life. Posterior transpedicular vertebral osteotomy can be used. 2. The indications for ankylosing spondylitis surgery are mainly ankylosing spondylitis with obvious spinal kyphosis, accompanied by intractable low back pain, and some patients may have limited vision and poor results of medication. 3. The so-called posterior transpedicular vertebral osteotomy is a method of removing the bone in the spine and then correcting the kyphosis with pedicle screws, which involves certain risks. 4. Some ankylosing spondylitis vertebral kyphosis is caused by pain and activity of the condition. Regular anti-rheumatic therapy can be given by visiting a rheumatology department, as well as visiting a rehabilitation department to give moderate functional exercises to correct the condition may also help to alleviate it. Patients with ankylosing spondylitis to correct the kyphosis should seek prompt medical attention and actively cooperate with their doctors.
