Pectineal ligament

The pectineal ligament (sometimes known as the inguinal ligament of Cooper, after Astley Cooper) is an extension of the lacunar ligament that runs on the pectineal line of the pubic bone.

It was characterized by Cooper in 1804. The structure is strong and holds suture well, facilitating reconstruction of the floor of the inguinal canal. This variant of non-prosthetic inguinal hernia repair, first used by Lotheissen in Austria, now bears his name.
