Brachial neuritis or Parsonage-Turner syndrome: A problem of liability. A presentation of 3 cases.

Neuralgic amyotrophy, brachial neuritis or Parsonage-Turner syndrome is a rare neuromuscular involvement of unknown aetiology. When it onsets in connection with a health care act, such as childbirth or surgery, a malpractice argument is often used as a cause of adverse outcome, usually due to an incorrect position of the patient on the operating table, a circumstance which directly involves the anesthesia area. Three cases are presented of Parsonage-Turner syndrome following very different surgery, with different results as regards prognosis. A review and discussion of bibliography is presented on the possibility that such circumstances are the subject of malpractice claims. Special emphasis is placed on the most currently accepted aetiopathogenic theories, and the relationship of this syndrome with the surgical act as a determining medico-legal aspect. Valuation parameters are proposed.
