Thelacunar ligament,also namedGimbernat's ligament,is a ligament in theinguinal region.[1]It connects theinguinal ligamentto thepectineal ligament,[2]near the point where they both insert on thepubic tubercle.[3]
Structure
[edit]The lacunar ligament is the part of theaponeurosisof theexternal oblique musclethat is reflected backward and laterally and is attached to the pectineal line of the pubis.
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.
Itsbaseis concave, thin, and sharp, and forms the medial boundary of thefemoral ring.Itsapexcorresponds to thepubic tubercle.
Itsposterior marginis attached to the pectineal line, and is continuous with thepectineal ligament.Itsanterior marginis attached to theinguinal ligament.
Its surfaces are directed upward and downward.
Clinical significance
[edit]The lacunar ligament is the only boundary of thefemoral canalthat can be cut during surgery to release afemoral hernia.Care must be taken when doing so as up to 25% of people have an aberrantobturator artery(corona mortis) which can cause significant bleeding.[4]
History
[edit]The lacunar ligament is sometimes calledGimbernat's ligamentafterAntoni de Gimbernat.[5]
