obturator nerve neuropathy
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.
Etiology
- trauma
- hip replacement complications (screws, cement)
- myositis ossificans
- pelvic tumors
- obturator hernia: see Howship-Romberg sign
- acetabular paralabral cyst
