The aim of the study was to compare the effects of corticosteroid injection with lidocaine injection in treating tennis elbow.
It is a prospective, double-blinded, randomized controlled trial. Patients with tennis elbow for more than 1 mo were recruited from a hospital-based rehabilitation outpatient clinic. A total of 70 patients were recruited, and 61 patients completed the study. Patients received an injection of either 10 mg (1 ml) of triamcinolone (corticosteroid group, n = 30) or 1 ml of 1% lidocaine (lidocaine group, n = 31). All of the outcome measures were evaluated before the intervention and at 2 wks and 2 mos after treatment.
No significant group differences were observed between the corticosteroid and lidocaine groups regarding Patient-Rated Tennis Elbow Evaluation, Disability of the Arm, Shoulder, and Hand, visual analog scale for pain, and grip strength at baseline and at 2 wks and 2 mos after treatment (P > 0.05). However, within-group comparison showed significant improvement after injection with regard to Patient-Rated Tennis Elbow Evaluation, Disability of the Arm, Shoulder, and Hand, visual analog scale for pain, and grip strength in both groups (P > 0.05).
No differences in the short-term outcomes were found between lidocaine and corticosteroid injection in a small sample of people with tennis elbow with mean duration of 3.8 mos.
本研究旨在比较皮质类固醇注射与利多卡因注射治疗网球肘的效果。
前瞻性、双盲、随机对照试验。从基于医院的康复门诊招募患有网球肘超过 1 个月的患者。共招募了 70 名患者，其中 61 名完成了研究。患者接受 10 mg（1 ml）曲安奈德（皮质类固醇组，n = 30）或 1 ml 1%利多卡因（利多卡因组，n = 31）注射。所有结局指标均在干预前和治疗后 2 周和 2 个月进行评估。
皮质类固醇组和利多卡因组在基线时和治疗后 2 周和 2 个月的患者自评网球肘评估、手臂、肩部和手部残疾、疼痛视觉模拟量表和握力方面，组间差异无统计学意义（P > 0.05）。然而，组内比较显示两组在注射后患者自评网球肘评估、手臂、肩部和手部残疾、疼痛视觉模拟量表和握力均有显著改善（P > 0.05）。
在患有平均病程为 3.8 个月的网球肘的小样本患者中，利多卡因和皮质类固醇注射在短期结局方面无差异。
