Editing Inguinal region (section)

== '''Important structures near inguinal region''' ==

* '''Inguinal     ligament''' - see     above under EO
* '''Lacunar     ligament'''     (Gimbernat's ligament): occurs as the inguinal ligament fans out medially.     This fanning allows it to have a broader insertion onto the pectineal     ligament. The lacunar ligament is also the medial border of the femoral     space.
** In its lateral border, may      contain an aberrant branch between obturator artery and EIA/DIEA (25% of      patients) which can be difficult to control if injured. Also known as      corona mortis artery, or if it is quite small, as the 'pubic branch' of      IEA. Can be accompanied by veins. See 'femoral hernia' topic.
** Named for the vascular      'lacuna' or opening, for which it forms the medial border
* '''Pectineal     ligament'''     (Cooper's ligament) is formed with contributions from lacunar ligament,     IO, TA and pectineus. It inserts onto the pectineal line of the pubic     bone, overlying the pectineus muscle. It is usually about 6cm long. It is     the posterior border of the femoral space.
** Both lacunar and pectineal      ligaments are robust anchoring points for hernia repairs - very thick,      tough, fibrous band.

* '''Conjoint     tendon''' - see     above under IO
* '''Iliopectineal     arch''' and '''iliopubic     tract''' - see     above under TA
* '''Interfoveolar     ligament'''     (Hesselbach's ligament) - thickening at lateral edge of internal ring,     made up of fibres derived from the transversus abdominis muscle
** This ligament pulls the      inguinal canal closed when transversalis fascia contracts, by functioning      as a sling around the internal ring
