Lumbar intervertebral disc prolapse is caused by compression of the nerve root by the prolapsed intervertebral disc tissue. With age, the intervertebral disc undergoes degenerative disease, the water content of the annulus fibrosus and nucleus pulposus gradually decreases, the nucleus pulposus loses its elasticity, and the annulus fibrosus gradually appears to be cracked. Under the action of chronic strain and external force, the intervertebral disc will rupture, and the nucleus pulposus fibrous annulus will prolapse backward, and the prolapsed tissues will compress the nerve root, resulting in symptoms such as lumbar pain, buttock pain, radiating pain in the lower limbs, numbness and weakness, and lightness of the feet, etc. Prolapsed disc is a relatively serious type of herniated disc. Patients with lumbar disc prolapse should consult the spine surgery or orthopedics department in time to improve the imaging examination, and then take targeted treatment measures according to the examination results.
