Lumbar disc herniation in the elderly is often combined with lumbar spinal stenosis, including disc degeneration vertebral gap shortening, osteophytes, hypertrophy of the ligamentum flavum, ossification of the posterior longitudinal ligament and other pathological changes that compress the nerve, resulting in lower limb numbness, weakness, or with pain. Once the neurological symptoms and imaging changes are obvious, early surgical decompression intervertebral support fusion treatment can relieve the symptoms and restore most of the functions of the nerve, if the long-term compression of the nerve leads to cell necrosis it is difficult to restore the surgical field, so early surgery is good for functional recovery.
