Ultrasound images obtained during obturator nerve block. The probe was shifted medially and directed cranially. A hyperechoic thick fascia between the pectineus and obturator externus muscles (open triangles) is the target plane. The needle (blue arrow) was moved toward the fascial plane deep to the pectineus (PE) muscle using an out of plane method. LA: local anaesthetic; AB: anterior branch of obturator nerve; SPR: superior pubic ramus (arrows); OE: obturator externus
