Structure
Variations in origin and course of obturator artery. (Obturator canal not labeled, but visible at bottom center of each diagram.)

The obturator canal is formed between the obturator membrane and the pelvis.[1] The obturator artery, obturator vein, and obturator nerve all travel through the canal.

Clinical significance

An obturator hernia is a type of hernia involving an intrusion into the obturator canal.

The obturator nerve can be compressed in the obturator canal.[2]

The obturator canal may be compressed during pregnancy and major traumatic injuries, causing obturator syndrome.[3]
