Following publication of the original article [1], the authors reported an error in: the authors’ institution and the Fig. 2 has a minor adjustment. Because Our author’s institution has recently made a change, so I must to replace all the authors’ institution as follow:

Fig. 2

Ultrasound and magnetic resonance images. a. Ultrasound images of a novel suprainguinal fascia iliaca compartment block (FICB). (a) Ultrasound image for identification of the relevant structures for FICB. White arrows, fascia iliaca; *, needle; ASIS, anterior superior iliac spine; SM, sartorius muscle; IOM, internal oblique muscle; IM, iliac muscle; (b) local anesthetic around the FN. FI, fascia iliaca; FN, femoral nerve; FA, femoral artery; MED, medial; LAT, lateral. b. An axial T2- weighted fat-suppressed magnetic resonance image at the level of the fourth sacral vertebra shows medial spread of injectate (small white arrows) in a plane superficial to the IP muscle and deep to the FA and FV. IP: iliopsoas; ON: obturator nerve; FA: femoral artery; FV: femoral vein. c. An axial T2-weighted fatsuppressed magnetic resonance image at the level of the second coccygeal vertebra shows medial spread of injectate (white arrows) in a plane superficial to the IP muscle and diffuses below the pectineus muscle to obturator nerve (☆). PM: pectineus muscle; IP: iliopsoas; OE: obturator externus; OI: obturator internus
