Editing Inguinal canal (section)

The surface marking of the deep inguinal ring is classically described as half an inch above the midpoint of the inguinal ligament.<ref name="isbn0-443-07168-3">{{cite book |author=Susan Standring |title=Gray's Anatomy: The Anatomical Basis of Medicine and Surgery |publisher=Churchill-Livingstone |year=2004 |isbn=0-443-07168-3 |page=[https://archive.org/details/graysanatomyanat0000unse/page/1098 1098] |url=https://archive.org/details/graysanatomyanat0000unse/page/1098 }}</ref>

However, the surface anatomy of the point is disputed. In a recent study,<ref>{{cite journal |vauthors=Koliyadan S, Narayan G, Balasekran P |title=Surface marking of the deep inguinal ring |journal=Clin Anat |volume=17 |issue=7 |pages=554–7 |year=2004 |pmid=15376291 |doi=10.1002/ca.10257|s2cid=30726776 }}</ref> it was found to be in a region between the mid-inguinal point (situated midway between the [[anterior superior iliac spine]] and the [[pubic symphysis]]) and the midpoint of the [[inguinal ligament]] (i.e. midway between the [[anterior superior iliac spine]] and the [[pubic tubercle]]). Traditionally, either one of these two sites was claimed as its location. However, this claim is based upon the study's dissection of 52 cadavers, and may not reflect the live ''in vivo'' anatomy.

Some sources state that it is at the layer of the [[transversalis fascia]].<ref name="isbn0-7817-5309-0"/>
