Editing Inguinal region (section)

== '''Myopectineal orifice''' ==

* A general descriptor for the     space through which groin hernias occur
* First described by Fruchaud     in 1956
* Bounded medially by rectus     abdominis, inferiorly by pectineal ligament, laterally by psoas, and     superiorly by transversus abdominis/internal oblique muscles (transverse     arch)
* The below triangles has been     described as the 'critical view of safety' for laparoscopic inguinal     hernia repairs

* '''The five     triangles:'''
** '''Pain'''
*** The triangle is bounded       medially by spermatic vessels, and superiorly by iliopubic tract (or       maybe even up to 2cm above it)
*** Lateral femoral cutaneous       nerve of the thigh - lies on ilacus, midway between ASIS and DIEA, then       passing deep to fascia iliacus and below the iliopubic tract
*** Femoral nerve - lies in a       groove between psoas and iliacus muscles, approximately midway between       psoas and iliacus
*** Femoral branch of       genitofemoral nerve - main trunk is beneath fascia iliacus, between       spermatic vessels and the iliac artery, and bordering the psoas -       bifurcates close to deep ring - genital branch into canal, and femoral       branch into femoral sheath
*** Ilioinguinal nerve is not       usually seen laparoscopically but can still be injured by fixation

* '''Doom'''
** Contains external iliac      vessels
** Bounded by vas def medially      and spermatic vessels laterally
