Obturator nerve neuropathy

Last revised by Joachim Feger on 29 Oct 2024

Obturator nerve neuropathy is an entrapment neuropathy that occurs when the obturator nerve is compressed by surrounding structures. 

Pathology

It occurs as the nerve dives under the superior pubic ramus to enter the obturator foramen: the anterior division lies between adductor brevis, pectineus and adductor longus and the posterior division, between adductor brevis and adductor magnus.
