Patient Positioning:

The patient is placed in a prone position with the heels rotated laterally and a cushion pillow is used as an iliac wedge to facilitate the exposure of the skin surface in the coccygeal area.

Probe Positioning:

Use a transverse image for the sacral hiatus and dorsal sacrococcygeal ligament between the bilateral sacral cornua first, then rotate the probe by 90 ° to show the longitudinal view of the sacral hiatus and coccyx.

Epidural sacral infiltration
