Adductor Longus

Adductor Longus is a triangular muscle which is located in the exact same plane as pectineus. It forms the floor and medial boundary of the femoral triangle.

  • In horse riders, the rounded tendon of adductor longus frequently gets calcified as a result of its friction together with the horseback. This calcified tendon is named rider’s bone. Some authorities are of view that rider’s bone is a sesamoid bone, which sometimes grows in the tendon of adductor longus.
