In our study we describe the passage of the obturator nerve via the obturator canal, not the "obturator foramen," (2) since the obturator groove is converted to a canal by the superior margins of the obturator membrane and the obturator muscles. We also conclude that the point of the obturator nerve bifurcation is variable: intrapelvic, at the entrance of the obturator canal, or within or at the exit of the obturator canal, and is the object of a separate investigation.

A triangular region bordered by the superior pubic ramus, posterior margin of the pectineus muscle and anterior aspect of the external obturator muscle containing the obturator vessels and nerve was defined and later used clinically to perform obturator nerve block with ultrasound guidance.
