ABSTRACT
INTRODUCTION:
We conducted a randomized, double-blind, placebo-controlled trial to evaluate the effect of ultrasound-guided corticosteroid injection in patients with ulnar neuropathy at the elbow (UNE).METHODS:
Fifty-five patients were randomized between an ultrasound-guided injection of 1 ml containing 40 mg methylprednisolone acetate and 10 mg lidocaine hydrochloride or a placebo injection. The primary outcome was the subjective change of symptoms after 3 months. The secondary outcomes were change in electrodiagnostic studies and ultrasonography findings.RESULTS:
A success rate of 30% was found in the corticosteroid injection group versus 28% in the placebo injection group. Only the nerve cross-sectional area changed significantly in the intervention group, from a mean of 11.9 mm(2) to 10.9 mm(2) .CONCLUSIONS:
We could not demonstrate a positive effect of ultrasound-guided corticosteroid injection in UNE compared with placebo. Favorable outcomes may be attributed to the natural course of UNE or the effect of patient education.Palavras-chave
