Pectineal ligament
Updates to Article Attributes
Body
was changed:
The pectineal ligament (also(somewhat confusingly also known as the inguinal ligament of Cooper) is an extension of the lacunar ligament that runs along the pectineal line of the pubis (also known as the pecten pubis).
Gross anatomy
The pectineal ligament is a highly resistant structure that runs along the pecten pubis on the superior ramus of the pubic bone. It is formed from:
fibres of the lacunar ligament
periosteum along the superior pubic ramus
aponeurotic fibres from the internal oblique muscle, transversus abdominis muscle and pectineus muscle 1
Some regard it as a thickening in the upper portion of the pectineal fascia.
Attachments
The pectineal ligament attaches medially to the pubic tubercle, where it meets the inguinal ligament and the lacunar ligament. It runs laterally along the pecten pubis, and slowly thins out along this course. It forms the posterior border of the femoral canal 2.
History and etymology
It was first described by Sir Astley Paston Cooper, (1768-1841) an English surgeon and anatomist, in 1804 3.
