Brachial<unk>  is often caused from local trauma to the brachial plexus, as can happen from a dislocated shoulder. The disorder can also be secondary to compression or stretching of the brachial plexus (for example, during a baby's transit through the birth canal, in which case it may be referred to as Erb's Palsy or Klumpke's palsy). Non-traumatic causes of brachial<unk>  include diabetes, malignancy, and infection. Brachial<unk>  can also be idiopathic with an unknown cause, in which case it is known as Parsonage-Turner Syndrome. Both brachial and lumbosacral<unk>  can also occur as a consequence of radiation therapy, sometimes after 30 or more years have passed, in conditions known as Radiation-induced Brachial<unk>  (RIBP) and Radiation-induced Lumbosacral<unk>  (RILP).
