The Effect of Perineural Dextrose Injection in Patients With Ulnar Neuropathy at the Elbow

Ulnar neuropathy at the elbow (UNE) is the second most common neuropathy and occurs after recurrent or elongated elbow flexion. Diagnosis of UNE depends on clinical symptoms, physical examination, and electrophysiological findings. Imaging methods such as ultrasonography (USG) and magnetic resonance imaging show cross-sectional area and echogenicity of ulnar nerve and give information about to surrounding structures around the ulnar nerve. In mild and moderate cases, conservative treatments are administered up to 6 months, who do not benefit from conservative treatment are referred to surgery. There are not many options for conservative treatment. Activity modification, nerve gliding exercises and night splints are conservative treatment methods. Steroid injection is no longer recommended. Perineural dextrose injection is applied in tendinopathies and entrapment neuropathies (especially carpal tunnel syndrome). In the literature, there is no study showing effect of perineural dextrose injection in patients with UNE. The investigators design a randomized, double-blind, controlled trail to evaluate the effect after ultrasound-guided perineural injection with 5% dextrose in patients with UNE.
