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

After obtaining written informed consent, patients of clinically diagnosed with UNE were randomized into intervention and control group. Participants in intervention group received one‐session ultrasound‐guided perineural injection with 5% dextrose and control group received one‐session ultrasound‐guided perineural injection with normal saline. No additional treatment after injection through the study period. The primary outcome is visual analog scale (VAS) and secondary outcomes include Quick‐DASH (Disabilities of Arm, Shoulder and Hand), cross‐sectional area (CSA) of the ulnar nerve, motor nerve conduction velocity and distal latency of the ulnar nerve. The evaluation was performed pretreatment as well as on the 2nd week, 1st and 3rd month after the treatment.
