Nerve injury

Peripheral nerve injury can cause severe limb dysfunction and even permanent disability. Peripheral nerve injury is mainly caused by trauma, birth injury, bone developmental abnormalities, lead and alcohol poisoning, etc., resulting in sensory disturbances, motor disturbances, and trophic disturbances in the area innervated by the affected nerve. Peripheral nerves refer to nerves outside the central nervous system (brain and spinal cord), including 12 pairs of cranial nerves, 31 pairs of spinal nerves, and autonomic nerves (sympathetic and parasympathetic nerves).
