Overview

    • Feel For

    • A palpable, enlarged peripheral nerve - often more than 5mm in diameter.
    • Common Sites to Palpate

    • Ulnar nerve - between the medial epicondyle and olecranon at the elbow
    • Median nerve - over the palmar aspect of the wrist
    • Radial nerve - in the snuffbox
    • Causes of Peripheral Nerve Enlargement

    • Leprosy
    • Charcot-Marie-Tooth
    • Neurofibromatosis
    • Chronic inflammatory demyelinating polyneuropathy

Ulnar Nerve Subluxation

    • How to Elicit

    • Palpate the ulnar nerve while the patient flexes and extends their elbow. Note whether the ulnar nerve is transposed anteriorly over the medial epicondyle.
    • Significance

    • Ulnar nerve subluxation is often normal, though may be a cause of cubital tunnel syndrome.
