How long a person with spondylitis lives cannot be generalized, but needs to be taken into account in the context of the specific disease. Simple spondylitis is generally rarely life-threatening, and patients can maintain a normal survival period. If spondylitis leads to spinal nerve damage, it may cause dysfunction and can be life-threatening in severe cases. There are many causes of spondylitis, but the pathological changes are mainly aseptic inflammatory reactions. Patients mainly present with localized pain in the thoracic back, predominantly with activity pain, which may sometimes be combined with nocturnal resting pain. Treatment is mainly based on non-steroidal anti-inflammatory and analgesic drugs, and if the compression of nerves causes spinal cord injury, surgery may be required if necessary. For spondylitis the focus is on prevention, usually should strengthen the functional exercise of the muscles of the low back, avoid prolonged sedentary or heavy physical labor, if there is long-term low back pain, should promptly go to the hospital for examination.
