The purpose of this study was to identify the results of ultrasound-guided injection of corticosteroid for biceps brachii tendinitis. In this randomized and prospective study, we evaluated 45 patients who were treated by free-hand injection without ultrasound guidance (group A) and 53 patients who were treated by ultrasound-guided injection (group B). The mean age was 47 y (range, 28 to 72). The average follow-up was 33 weeks (range, 24 to 56). The visual analog scale score decreased from 7.1 ± 2.3 before injection to 4.2 ± 3.1 at follow-up in group A and from 6.9 ± 2.6 to 2.1 ± 1.9 in group B (p < 0.05). The Constant-Murley score improved from 31.4 ± 11.6 before injection to 73.5 ± 19.2 at follow-up in group A and from 32.5 ± 14.7 to 85.5 ± 10.3 (p < 0.01). The ultrasound-guided injection therefore demonstrated a statistically significantly greater degree of pain relief. However, the outcome of injection was not satisfactory for the patients who demonstrated severely frayed tendons at arthroscopy. There were no complications related to the injection in both groups. Corticosteroid injection under ultrasound guidance is a safe and well-tolerated procedure with a satisfactory rate of symptom relief in patients with biceps brachii tendinitis.
本研究旨在探讨超声引导下肱二头肌长头肌腱炎皮质类固醇注射的疗效。本研究为随机前瞻性研究，共纳入 45 例采用徒手注射（A 组）和 53 例超声引导下注射（B 组）的患者。平均年龄 47 岁（2872 岁）。平均随访 33 周（2456 周）。A 组患者视觉模拟评分（VAS）由注射前的 7.1 ± 2.3 分降至随访时的 4.2 ± 3.1 分，B 组由 6.9 ± 2.6 分降至 2.1 ± 1.9 分（p < 0.05）。A 组患者Constant-Murley 评分由注射前的 31.4 ± 11.6 分提高至随访时的 73.5 ± 19.2 分，B 组由 32.5 ± 14.7 分提高至 85.5 ± 10.3 分（p < 0.01）。超声引导下注射能显著缓解疼痛，但关节镜下发现肌腱严重磨损的患者疗效并不满意。两组均未发生与注射相关的并发症。超声引导下皮质类固醇注射是一种安全、耐受良好的方法，可有效缓解肱二头肌长头肌腱炎患者的症状。
