The difference between neonatal brachial plexus nerve injury and rupture is characterized by clinical manifestations, treatment methods and so on. 1. Symptoms: neonatal brachial plexus nerve injury usually occurs nerve shock, which makes the upper limbs appear abnormal function for a short time, accompanied by pain, burning sensation, but can be partially recovered on its own. For neonatal brachial plexus nerve rupture, the upper limbs will show paralysis, muscle atrophy, dyskinesia and other symptoms, and in severe cases, the function of the upper limbs will be completely lost. 2. Treatment: The treatment of neonatal brachial plexus nerve injury depends on the severity of the disease. If the condition is mild, it can be gradually recovered through functional training; if the condition is more serious, surgery is needed. In contrast, if a neonate suffers a brachial plexus nerve rupture, surgery should be performed immediately without delay to minimize the degree of permanent disability. Neonatal brachial plexus nerve injury and rupture belong to an inclusive relationship, both of which can have an impact on the healthy development of the newborn, so it is important to treat them as early as possible.
