3 – Scanning technique for the subgluteal approach

Place the patient in the lateral position

Place the low-frequency curved array probe in the gluteal crease. A linear probe can be used in lean patients

Visualize the target sciatic nerve (see next page)

Insert the needle from the lateral end of the probe with in-plane technique

Advance the needle tip to the target sciatic nerve

Inject 10-15 mL of local anaesthetic until complete perineural spread is obtained
