The ulnar nerve is a major peripheral nerve originating from the brachial plexus, crucial for sensory and motor function in the forearm and hand. As part of the “Nerve” category, its course along the medial epicondyle (“funny bone”) makes it susceptible to compression or injury. In medical and ultrasound diagnostics, evaluating the ulnar nerve is essential for diagnosing conditions like cubital tunnel syndrome or nerve entrapment.
Ultrasound offers a non-invasive, dynamic assessment of the ulnar nerve, visualizing its integrity, continuity, and any structural abnormalities or inflammation. This imaging modality aids in precisely localizing nerve pathology, guiding injections, and monitoring treatment efficacy, providing valuable insights for hand and wrist neuropathies.
