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]
