The lacunar ligament (also named Gimbernat’s ligament) is a ligament in the inguinal region that connects the inguinal ligament to the pectineal ligament near the point where they both insert on the pubic tubercle.
The inguinal and lacunar ligaments. (Lacunar ligament labeled at center top.)
|From||inguinal ligament, pubic tubercle|
|Latin||ligamentum lacunare (Gimbernati)|
It is about 1.25 cm. long, larger in the male than in the female, almost horizontal in direction in the erect posture, and of a triangular form with the base directed laterally.
Its surfaces are directed upward and downward.
The lacunar ligament is the only boundary of the femoral canal that can be cut during surgery to release a femoral hernia. Care must be taken when doing so as up to 25% of people have an aberrant obturator artery (corona mortis) which can cause significant bleeding.
