Abstract
This article is a practical review update on ultrasound (US)-guided interventional
procedures on peripheral nerves. Technical considerations, biopsy techniques, and
some examples of injections are described. US is considered a safe imaging guidance
for interventional procedures, due to its high spatial resolution and the possibility
to image the needle and inject drugs in real time. US-guided injections could be considered
a diagnostic and therapeutic option in the most common neuropathy, before or as an
alternative to surgery. US-guided injection techniques in patients with carpal tunnel
syndrome, cubital tunnel syndrome, meralgia paresthetica, and Morton neuroma are reviewed.
US-guided injections of the iliohypogastric, ilioinguinal, genitofemoral, and pudendal
nerve are also illustrated. Knowledge of anatomy is crucial; therefore a brief description
of the courses of anatomical nerves and clinical notes are also reported. Treatment
of stump neuromas treatment was excluded.
