Figure 1: (a) Ultrasound (US)-guided continuous erector spinae plane block. Erector spinae muscle (ESM)—brown outline; Tuohy needle—white broad short arrows; Catheter in erector spinae plane (ESP)—yellow broad short arrows. (b) Coronal image at the level costotransverse junctions; contrast spread from T4 to L4. Contrast spread in ESP—light green); cervicothoracic junction (CTJ)—(dark green arrows); fracture ribs—(red arrows). (c) Contrast in flow between the medial and intermediate ESMs. Medial and lateral ESM—purple; contrast spread from ESP to thoracic paravertebral space (TPVS)—light green; TPVS—light yellow. (d) Volume rendering technique (VRT) scan of erector spinae plane block. Contrast spread in ESP—light green; posterolateral rib fractures—red arrows
