PMID 38576834WHAT IT FOUND
Musculoskeletal ultrasound provides a non-invasive, real-time view of the ulnar nerve at the elbow, helping clinicians visualize structural issues like nerve instability or compression.
It serves as a useful adjunct to physical exams and nerve conduction studies, particularly when the diagnosis is unclear or anatomical variations are suspected.
Key findings
01Musculoskeletal ultrasound offers a real-time, dynamic approach to correlate imaging findings with clinical symptoms, which is valuable when the diagnosis of ulnar nerve pathology is uncertain.
02Traditional electrodiagnostic testing (EMG/NCS) has limitations in visualizing the morphology of the ulnar nerve and its surrounding tissues, making imaging indispensable for ambiguous cases.
03Ultrasound can visualize anatomical variations such as a shallow bony ulnar groove or nerve instability, which may contribute to symptoms even in the absence of clear entrapment.

What it does not show
This is a narrative review, not a systematic review or clinical trial, so it lacks the rigorous methodology needed to establish definitive diagnostic accuracy or treatment efficacy. The paper does not report specific sensitivity or specificity values for ultrasound compared to EMG/NCS in a head-to-head study. It does not provide evidence that using ultrasound directly improves patient outcomes or treatment success rates.
The easy way to misread this
Do not interpret this paper as evidence that ultrasound is superior to nerve conduction studies for diagnosing cubital tunnel syndrome. It is a descriptive review advocating for ultrasound as a complementary tool, not a replacement, and it does not present data proving that ultrasound use leads to better clinical outcomes.
