In human anatomy, the accessory obturator nerve is an accessory nerve in the lumbar region present in about 29% of cases. It is of small size, and arises from the ventral divisions of the third and fourth lumbar nerves. Recent evidence support that this nerve arises from Dorsal divisions. It descends along the medial border of the psoas major, crosses the superior ramus of the pubis, and passes under the pectineus, where it divides into numerous branches. Occasionally the accessory obturator nerve is very small and is lost in the capsule of the hip-joint.

Se origina del tercero y cuarto pares lumbares, sigue el trayecto del nervio obturador en su recorrido dentro de la pelvis y se separa de él en el pubis para pasar por encima de la rama horizontal del pubis, a diferencia del obturador que lo hace por el canal obturador.

- In human anatomy, the accessory obturator nerve is an accessory nerve in the lumbar region present in about 29% of cases. It is of small size, and arises from the ventral divisions of the third and fourth lumbar nerves. Recent evidence support that this nerve arises from Dorsal divisions. It descends along the medial border of the psoas major, crosses the superior ramus of the pubis, and passes under the pectineus, where it divides into numerous branches. One of these supplies the pectineus, penetrating its deep surface, another is distributed to the hip-joint; while a third communicates with the anterior branch of the obturator nerve. Occasionally the accessory obturator nerve is very small and is lost in the capsule of the hip-joint. When it is absent, the hip-joint receives two branches from the obturator nerve. (en)

Vienen a terminar en el músculo pectíneo y a veces en el aductor corto, después de haber dado filetes articulares. En ciertos casos va a anastomosarse directamente con una rama del femoral o del obturador. (es)
