Lesions in the peripheral nerves produce paralysis in the muscles that depend on them and an anesthetic effect in the areas of distribution of the same ones. These injuries can be caused by trauma, such as wounds or fractures, although there are tumors and compression lesions of the nerve trunks.
Symptoms of a peripheral nerve problem
The main symptoms of a peripheral nerve injury are paralysis and an anesthetic effect on the affected extremity. Unlike nerve lesions that originate in the medulla or brain, which produce paralysis with stiffness and spasticity, the paralysis of the peripheral nerves is flaccid.
Treatment of peripheral nerve injuries
Lesions in the peripheral nerves can be treated with different microsurgical methods , if they are detected in time. The main techniques are the decompression or neurolysis of compression zones, microsurgery or neurorrhaphy, with or without nerve grafts, depending on the lost distance of nerves, or the bypass of other nerves or neurotizations.
In the chronic phase, the establishment of paralytic upper or lower limbs can be treated with tendon transpositions of healthy tendons , microsurgical muscle transplants or fixation of the joints, arthrodesis, in a good position of the paralyzed zones.
When paralysis is due to central causes after stroke, brain or quadriplegia due to spinal cord injury, the treatment of spasticity will be done by a section of tendons, muscles or nerves , which will allow a better positioning of the affected extremities, allowing, in some cases Mobility of healthy muscles not affected.
