Résumé
Our goal was to revisit the innervation of the adductor muscles of the thigh and add new evidence to currently existing knowledge. Ten thighs from five fresh frozen cadavers were dissected. Obturator nerve innervation to the pectineus, obturator externus, adductor brevis, adductor magnus, adductor longus, and gracilis was documented. The adductor longus and gracilis were innervated by the anterior branch in 100%, and the adductor magnus was innervated by the posterior branch in 100%. The adductor brevis was supplied by both the anterior and posterior branches in 90%. The obturator externus was innervated by the posterior branch in 60% and a direct branch from the main trunk in 10%. No innervation of the obturator externus by the obturator nerve was found in 30%. The obturator externus and adductor brevis need to be explored further to clarify their innervation.

RESULTS
The adductor longus and gracilis were innervated by the anterior branch in 100%, and the adductor magnus was innervated by the posterior branch in 100%. The adductor brevis was supplied by both the anterior and posterior branches in 90%. The obturator externus was innervated by the posterior branch in 60% and a direct branch from the main trunk in 10%. No innervation of the obturator externus by the obturator nerve was found in 30%.
CONCLUSIONS
CONCLUSIONS
The obturator externus and adductor brevis need to be explored further to clarify their innervation.
