Congenital malformation of brachial plexus in cesarean delivery infants without trauma

Abstract

Brachial plexus palsy is a weakness or paralysis of the shoulder and hand region due to damage to the nerves of the brachial plexus complex (including roots C5, C6, C7, C8 and T1), affecting many to arm motor function and personal activities. This damage can occur in adults or children, mostly due to trauma. The term congenital brachial plexus palsy is now used to refer to cases in which a child is paralyzed at birth, usually due to complications in obstetrics, but very rarely the cases are true congenital, due to abnormalities of anatomical structures during fetal formation. In this article, we refer to a very rare case in clinical practice and radiology: unilateral brachial plexus palsy due to aplasia of the plexus nerve branches with accompanying other congenital anomalies of the cervical spine
in an infant by cesarean section.
