The aim of this prospective randomized study was to compare the efficacy of 3 injection methods, intra-articular injection, subacromial injection, and hydrodilatation (HD), in the treatment of primary frozen shoulder.
Patients with primary frozen shoulder were randomized to undergo intra-articular injection (n = 29), subacromial injection (n = 29), or HD (n = 28). Evaluations using a visual analog scale for pain, Simple Shoulder Test, Constant score, and passive range of shoulder motion were completed before treatment and 1 month, 3 months, and 6 months after treatment.
Among the 3 injection methods for primary frozen shoulder, HD resulted in a greater range of motion in forward flexion and external rotation, a lower visual analog scale score for pain after 1 month, and better outcomes for all functional scores after 1 month and 3 months of follow-up. However, there were no significant differences in any clinical outcomes among the 3 groups in the final follow-up at 6 months.
Although HD yielded more rapid improvement, the 3 injection methods for primary frozen shoulder resulted in similar clinical improvement in the final follow-up at 6 months.
这项前瞻性随机研究的目的是比较三种注射方法（关节内注射、肩峰下注射和液压扩张术（HD））治疗原发性冻结肩的疗效。
将原发性冻结肩患者随机分为关节内注射组（n = 29）、肩峰下注射组（n = 29）或液压扩张术组（n = 28）。在治疗前以及治疗后1个月、3个月和6个月，使用视觉模拟疼痛量表、简易肩部测试、Constant评分和肩部被动活动范围进行评估。
在原发性冻结肩的三种注射方法中，液压扩张术在1个月后前屈和外旋活动范围更大，疼痛视觉模拟量表评分更低，且在随访1个月和3个月后所有功能评分的结果更好。然而，在6个月的最终随访中，三组之间的任何临床结果均无显著差异。
尽管液压扩张术改善更快，但原发性冻结肩的三种注射方法在6个月的最终随访中临床改善相似。
