The causes of narrowing of the cervical spinal space include scoliosis, cervical tuberculosis, degenerative spinal osteoarthropathy, and so on, which can be treated by wearing a brace, physical therapy, using drugs such as isoniazid and celecoxib, or surgery. 1. Scoliosis: Scoliosis can lead to narrowing of the intervertebral space on one side, unequal height of both shoulders, spinal nerve compression and other symptoms. If the scoliosis angle is less than 20°, it can be followed up and observed. If the scoliosis angle is greater than 20° and the child is growing up, the brace should be worn 16-23 hours a day until maturity. If the scoliosis angle is more than 40°, surgery is usually needed. 2. Cervical spine tuberculosis: Cervical spine tuberculosis can cause low-grade fever, night sweats, neck pain, numbness of the upper limbs and other symptoms, which can destroy the intervertebral discs and lead to narrowing of the intervertebral space. It is necessary to pay attention to rest, strengthen nutrition, systemic use of isoniazid and other anti-tuberculosis drugs, local support can be worn to limit spinal activity, and in severe cases, surgery is needed. 3. Degenerative spondylolisthesis: Degenerative spondylolisthesis is common in the elderly, due to the loss of normal tissues caused by aging, resulting in narrowing of the intervertebral space, which may cause local pain, stiffness and other symptoms. Degenerative spondylolisthesis should avoid prolonged standing, and local blood circulation can be promoted through phototherapy and hydrotherapy to eliminate symptoms. Medications such as celecoxib can also be used to relieve symptoms. All of the above medications should be used under a doctor’s supervision, avoid self-medication. If the cervical spine space narrows, it is recommended to go to the hospital in time, with the help of the doctor to clarify the cause of the disease, and early and regular treatment.
