Treatment of ulnar neuropathy at the elbow – an ongoing conundrum

Ulnar neuropathy at the elbow (UNE) is the second most common mechanical mononeuropathy after carpal tunnel syndrome (CTS). Despite the frequency with which it is seen in the neurophysiology clinic, UNE still poses clinical and diagnostic challenges. The clinical diagnosis of ulnar neuropathy is generally easy to determine, but UNE may be difficult to localize on nerve conduction studies. Diagnostic localization is improved when the ulnar nerve is examined by ultrasound (Simon et al., 2015) and best with magnetic resonance neurography (Keen et al., 2012).
