Nucleus pulposus prolapse is a more serious condition and a serious type of lumbar disc herniation. The human lumbar disc can be surrounded by an annulus fibrosus, where the fibers form a ring of tissue with the nucleus pulposus in the middle. If the nucleus pulposus falls out completely and into the spinal canal, it is a lumbar disc nucleus pulposus prolapse. Symptoms of prolapse are difficult to relieve with conservative treatment. If the lumbar spinal canal is large and the nucleus pulposus does not cause significant pressure on the spinal cord or nerve roots, conservative treatments, such as changing position and applying heat, can be performed. However, if the nucleus pulposus has completely prolapsed, it can compress the nerve roots and spinal cord, and surgical treatment is needed to remove the nucleus pulposus from the spinal canal in order to completely remove the cause of the disease. It is recommended to go to the hospital in time, under the guidance of the doctor’s treatment.
