 injured in the operation for the relief of a strangulated femoral hernia. 



(2) Arteria Circumflexa Ilium Profunda. The deep circumflex iliac artery 



(Figs. 774 and 777) springs from the lateral side of the external iliac artery, usually 

 a little below the inferior epigastric, and immediately above the inguinal ligament. 

 It runs laterally and upwards to the anterior superior spine of the ilium. In that 

 part of its course it lies just above the lower border of the inguinal ligament, and 

 is enclosed in a fibrous canal formed by the union of the transversalis and iliac 

 fasciae. A little beyond the anterior superior spine it pierces the transversus
