Narrowing of the lumbar 5-sacral 1 spinal space is considered to be caused by degenerative disease of the lumbar 5-sacral 1 disc in most cases. After degenerative disc disease, the disc becomes less elastic and less watery, which can lead to herniation of the disc. After the disc generally protrudes posteriorly, it causes narrowing of the intervertebral space. If there are no obvious symptoms, no special treatment is needed, but you should also actively correct your body posture, avoid a long time a posture, change your posture regularly; strengthen the warmth, avoid getting cold, avoid sitting and standing for a long time, avoid bending, not to mention bending to bear weight; you can use the lumbar circumference to fix, take it down when resting in bed; appropriate functional exercise of the muscles of the low back. If local symptoms of low back pain, leg pain and leg numbness appear, anti-inflammatory and analgesic drugs can be applied for symptomatic treatment, such as diclofenac sodium, the drug to relieve muscle spasm, ethylprednisolone hydrochloride, dehydration and swelling treatment with intravenous mannitol injection to reduce the pressure in the spinal canal, and nerve-nourishing drugs such as methylcobalamin capsules for treatment. If conservative treatment is ineffective and nerve damage is severe, surgery is required.
