Clinical and radiological characteristics of natally conditioned flaccid paresis of the upper extremities

Natally conditioned sluggish paresis of the upper extremities is an integral part of the problem of birth injuries of the central nervous system. For many decades, the cause of paresis, or the so-called obstetric paralysis, was considered to be damage to the brachial plexus during childbirth, therefore in the literature they are known as generic plexitis of Erb or Dejerin-Klumpke, depending on which suffered more - the proximal or distal muscles. Currently, the cause of obstetric paralysis is considered to be trauma to the cervical spine, spinal cord and adjacent vessels due to damage to the radicular-spinal arteries [3, 7].
