Positive straight leg raising test, limited lumbar spine motion, straightening of the anterior spine, localized percussion pain, and spasm of the erector spinae. These symptoms are from mononeuropathy versus plexiform neuropathy. Spinal peripheral neuropathy refers to structural and functional disorders of axons and (or) Schwann (Schwann) cells and myelin sheaths of motor neurons, primary sensory neurons, and peripheral autonomic neurons in the spinal cord and lower brainstem. Then, how should patients with anterior spinal straightening localized percussion pain be diagnosed? Here is a brief introduction: 1, lumbosacral nerve root, plexus and nerve trunk damage must be differentiated from lumbar muscle strain, hip fibrositis, hip arthritis, etc. The latter can cause pain in the lower back, buttocks and lower limbs, but there is no radiating pain, no hypotonia, ankle reflexes and sensory disturbances. 2.Differentiation of etiology should pay attention to spinal cauda equina tumor, degenerative spondylitis (proliferative spondylitis), spinal tuberculosis, tumor, cryptic fissure, spinal cord cavernous disease, biceps tenosynovitis, pyriformis syndrome and so on. Spinal X-rays, CT, or MRI can help confirm the diagnosis. The main concern is to prevent damage to the peripheral nerves from various primary causes. In the treatment, neurotrophic metabolism drugs should be used as early as possible, such as B vitamins, vitamin E, cytarabine, ATP, coenzyme A, and nerve growth factor and other drugs, or can promote the improvement of nerve function.
