Monoplegia

Introduction Single scorpion, one of the limbs appears screaming as a single scorpion. Single sputum can be caused by peripheral neuropathy and central neuropathy. Lesions can be located in the anterior horn of the spinal cord, anterior root, plexus, and peripheral nerves. Acute morbidity is seen in trauma. When the peripheral nerve is damaged, the muscles or muscles of the innervation are reduced or disappeared, and the corresponding sputum reflexes disappear. The long-term serious damage often shrinks. Mostly caused by local trauma, fracture, decompression, pressure, ischemia and so on.

Cause

Acute morbidity is seen in trauma, and gradually taking off is seen in the compression of nerve plexus and nerve roots, such as the compression of tumors and neck ribs. The anterior or anterior horn lesions are segmental. There is no sensory disturbance in the lesion of the simple anterior horn, acute gray inflammatory disease in the acute, progressive spinal muscular atrophy in the chronic, muscle atrophy is more obvious than sputum, and there is fasciculation. Similar chronic spasms can occur in syringomyelia and anterior horns, but there are segmental pain, loss of sense of the sense of the ear and the separation of the sense of touch. Anterior root damage is often accompanied by root pain and segmental sensory disturbance due to simultaneous damage to the posterior root. Common causes of radiculopathy are tumors of the meninges and spine, inflammation, tuberculosis, trauma, and herniated discs.

Clinically, a single sputum lesion is located in the cortex or subcortical area, and the sputum can be central. If the lesion is located in the anterior horn of the spinal cord, the anterior root, and the peripheral nerve, the sputum is peripheral. The plexus lesion is the entire upper or lower extremity paralysis with sensory disturbance. When the brachial plexus is damaged, the entire upper limb muscle is flaccid paralysis, and various sensations below the arm disappear, which may be caused by brachial plexus neuritis, trauma, tumor compression, and the like.

Differential diagnosis

Differential diagnosis of single sputum:

1, lower extremity muscle spasm: lower extremity muscle spasm is a symptom of spinal cord compression.

2, quadriplegia: quadriplegia refers to the decline or disappearance of the free movement of the limbs.

3, the upper limbs around the sputum: peripheral sputum, also known as the lower motor neuron sputum, or flaccid paralysis, soft palate. It is caused by the damage of the anterior horn cells of the spinal cord and the brain to the motor nucleus, and the fibers of the anterior root, spinal nerve, and cranial nerves. Peripheral paralysis of the upper extremity refers to the peripheral paralysis of the upper limb in the affected part.

4, hemiplegia: Hemiplegia, also called hemiplegia, refers to the movement disorders of the upper and lower limbs, the facial muscles and the lower part of the tongue. It is a common symptom of acute cerebrovascular disease. Although mild hemiplegia patients can still move, but when they walk, they tend to flex their upper limbs, straighten their lower limbs, and take a half circle in the lower limbs. This special walking posture is called hemiplegic gait. Severe cases are often bedridden and lose their ability to live. According to the degree of hemiplegia, it can be divided into sputum, incomplete sputum and sputum. Flick: manifested as weak muscle strength, muscle strength in 4-5, generally does not affect daily life, incomplete sex is lighter and heavier, the range is larger, muscle strength is 2-4, full : muscle strength 0- Level 1, the limbs are completely inactive.

5. Paraplegia: refers to a condition in which the bilateral limbs feel, movement, reflexes, and the bladder and anal sphincter function are lost after the spinal cord injury. Among them, those who have completely lost the above functions, called complete paraplegia, and some functions exist, said incomplete paraplegia. In the early stage, it is a flaccid paralysis. After about 3 to 4 weeks, it gradually turns into a sputum. The cause of paraplegia is related to spinal cord trauma or its own pathology.
