2026 Workshop Handout Bundle-W92RG Advanced Nerve US - Lower Limb

W92RG Advanced Nerve US - Lower Limb - Comer Miller Olson

Pdf Summary

This 2026 AANEM workshop handout is a practical ultrasound checklist for evaluating major lower-limb peripheral nerves. It outlines each nerve’s anatomy, patient positioning, scanning approach, landmarks, and common sites of injury or compression.<br /><br />The checklist covers the sciatic nerve and its tibial and common fibular components; the deep and superficial fibular nerves; the tibial nerve in the thigh, leg, and tarsal tunnel; the sural nerve; and the lateral femoral cutaneous nerve. It describes their spinal-root origins, motor and sensory territories, courses, and major branches.<br /><br />Scanning generally begins in short axis and follows the nerve along its course, using nearby muscles, tendons, vessels, and bony landmarks for identification. Long-axis views can help assess focal versus diffuse enlargement or constriction. The handout highlights clinically useful landmarks and vulnerable regions, including the common fibular nerve at the fibular neck, the deep fibular nerve at the anterior ankle, the superficial fibular nerve as it becomes subcutaneous, the tibial nerve in the tarsal tunnel, and the lateral femoral cutaneous nerve near the ASIS and inguinal ligament.<br /><br />Across all nerves, the examiner should look for trauma, focal enlargement, compressive masses, and abnormal surrounding soft tissues. Particular considerations include ganglion cysts and tendon-sheath inflammation near the tarsal tunnel, and the use of ultrasound to guide therapeutic injections around the lateral femoral cutaneous nerve. The handout also notes anatomical variation, such as differences in sural nerve formation.
