Abstract/Notes

Objective: To describe an anatomical variant wherein, bilaterally, the C5 ventral root passes anterior to the anterior scalene muscle.

Clinical Implications: This and other variants in the anatomy of brachial plexus may complicate diagnosis of thoracic outlet syndrome, by producing unconventional signs and symptoms. Additionally, the passage of C5 ventral root anterior to the anterior scalene muscle, as in this case, may render the nerve root more susceptible to injury, including injury during manual therapy directed to this region.

Scalène antérieur et racine nerveuse C5 du plexus brachial : variation anatomique bilatérale et sa signification en clinique

Objectif : Décrire une variante anatomique selon laquelle, bilatéralement, la racine ventrale de C5 passe en avant du scalène antérieur.
Incidence clinique : Cette variante et d’autres dans l’anatomie du plexus brachial peuvent compliquer le diagnostic du syndrome du défilé thoracique, parce qu’elles produisent des signes et des symptômes inhabituels. Par ailleurs, le passage de la racine ventrale de C5 en avant du scalène antérieur, comme c’est le cas ici, peut rendre la racine nerveuse plus exposée aux blessures, notamment pendant des manipulations dans cette région.

Mots-clés de l'auteur: syndrome du défilé thoracique, variante anatomique, racine ventrale de la C5, cadavre
