AANEM Practice Topic: Evidence-based guideline: Neuromuscular ultrasound for the diagnosis of ulnar neuropathy at the elbow
Monograph: Evidence-based guideline: Neuromuscular ultrasound for the diagnosis of ulnar neuropathy at the elbow
Introduction/Aims: The purpose of this literature review is to develop an evidence-based guideline for the use of neuromuscular ultrasound in the diagnosis of ulnar neuropathy at the elbow (UNE). The proposed research question was: “In patients with suspected UNE, does ulnar nerve enlargement as measured with ultrasound accurately identify those patients with UNE?”
Methods: A systematic review and meta-analysis was performed, and studies were classified according to American Academy of Neurology criteria for rating articles for diagnostic accuracy.
Results: Based on Class I evidence in four studies, it is probable that neuromuscular ultrasound measurement of the ulnar nerve at the elbow, either of diameter or cross-sectional area (CSA), is accurate for the diagnosis of UNE.
Recommendation: For patients with symptoms and signs suggestive of ulnar neurop-athy, clinicians should offer ultrasonographic measurement of ulnar nerve cross-sectional area or diameter to confirm the diagnosis and localize the site of compres-sion (Level B).
