Valleix's Sign.

Ann Plast Surg

Johns Hopkins University, Baltimore, MD.

Published: September 2024

AI Article Synopsis

  • Some patients experience localized pain linked to specific nerves, known as the "Valleix phenomenon," particularly affecting nerves like the ulnar and sciatic nerves.
  • The article explores François Louis Isidore Valleix's 1841 book on neuralgia, which details various nerve pain conditions and may represent the first observations of specific pain points linked to nerves.
  • Valleix's work included descriptions of nerve compression syndromes like cubital and fibular tunnel syndromes, and although he identified several rare compression sites, he did not mention the now-common median nerve compression at the wrist.

Article Abstract

Some patients present with clinical symptoms of localized tenderness and pain associated with a specific peripheral nerve, such as the ulnar nerve at the elbow or the sciatic nerve, which has been called, although rarely, "Valleix point" or "Valleix phenomenon". The purpose of this article was to translate and research the 719-page book "Traité des névralgies ou affections douloureuses des nerfs" dated 1841, dedicated solely to nerve pain (neuralgia), written by the French physician François Louis Isidore Valleix (1807-1855). He may have been the first person to observe and describe this phenomenon of localized pain, but he was probably also the first to describe distal nerve radiation, which he called "élancement" or lancinating, or stabbing. He described the phenomenon of a nerve producing pain at points along its course that we now understand to be sites of compression, clearly describing cubital and fibular tunnel syndromes, which he called neuralgias. He also described some rarer sites of compression, such as supraorbital and occipital neuralgia, notalgia paresthetica, and ACNES, but he did not describe the most common site of compression today, the median nerve at the wrist. Valleix's descriptions are clear and precede the classic 1915 reports of Hoffmann's and Tinel's signs by 74 years.
