Abstract：
Shoulder dislocation, particularly anterior dislocation, is a common orthopedic injury often presenting in emergency care settings, characterized by significant pain and muscle spasms. Prompt reduction is essential to alleviate symptoms and restore function. The Cunningham technique employs gentle pulling and massage motions targeted at the muscles and has emerged as a promising method for reducing anterior shoulder dislocations. However, its reported success rates vary widely across studies, and questions remain regarding its efficacy, particularly in cases of failure. This study aims to evaluate the effectiveness of the Cunningham technique for reducing anterior shoulder dislocations and its potential role in providing analgesia and muscle relaxation as an adjunctive method.
A retrospective study was conducted on patients presenting with acute anterior shoulder dislocation at a single center. Reduction using the Cunningham technique was performed initially, followed by the external rotation technique if unsuccessful. Procedural sedation and analgesia were administered if the reduction was still not achieved, and shoulder dislocation reduction was performed again through the external rotation method. The patients\' VAS scores were recorded and evaluated the Cunningham technique\'s effectiveness in reduction and whether it increases the effectiveness of other techniques applied for reduction by lowering the VAS score, even in cases where it is not effective.
A total of 61 patients were included in the study. The reduction was performed using the Cunningham technique in 34.4% (21/61) patients, the external rotation technique in 47.5% (29/61) patients, and the external rotation technique with PSA in 18% (11/61) patients. Significant differences were observed in the duration of hospital stay among the three techniques, with ER with PSA resulting in the longest stay. VAS scores showed significant improvements from initial presentation to post-reduction in all three groups. A significant decrease in pre-reduction VAS scores was observed during the transition from the Cunningham technique to other techniques.
The Cunningham technique showed effectiveness in reducing anterior shoulder dislocations, providing analgesia, and muscle relaxation. It demonstrated favorable outcomes as an initial reduction technique, with the external rotation technique used as a subsequent option. Further studies comparing the success rates and complications of the Cunningham technique with other reduction methods are warranted to establish its role in clinical practice.

摘要：
背景：肩关节脱位，尤其是前脱位,是一种常见的骨科损伤，通常在紧急护理环境中出现，以明显的疼痛和肌肉痉挛为特征。迅速减少对于缓解症状和恢复功能至关重要。坎宁安技术采用针对肌肉的轻柔的牵拉和按摩动作，已成为减少肩关节前脱位的一种有前途的方法。然而,报告的成功率在不同的研究中差异很大，关于其功效的问题仍然存在，尤其是在失败的情况下。这项研究旨在评估坎宁安技术减少肩关节前脱位的有效性及其在提供镇痛和肌肉松弛作为辅助方法方面的潜在作用。
方法：对单中心急性肩关节前脱位患者进行回顾性研究。最初使用坎宁安技术进行还原，如果不成功，则进行外部旋转技术。如果仍未实现减少，则给予程序镇静和镇痛，并通过外部旋转方法再次进行肩关节脱位复位。记录患者的VAS评分，并评估Cunningham技术的有效性，以及它是否通过降低VAS评分来增加其他技术的有效性。即使在没有效果的情况下。
结果：共61例患者纳入研究。34.4％（21/61）的患者使用Cunningham技术进行了复位，47.5%(29/61)的患者采用外旋技术，18％（11/61）的患者采用外旋转技术进行PSA。三种技术在住院时间上有显著差异,ER与PSA导致最长的逗留。在所有三组中，VAS评分从最初的表现到后的降低都显示出显着的改善。在从坎宁安技术过渡到其他技术的过程中，观察到还原前VAS评分显着降低。
结论：Cunningham技术可有效减少肩关节前脱位，提供镇痛，肌肉放松。它证明了作为一种初始还原技术的有利结果，使用外部旋转技术作为后续选项。有必要进一步研究比较坎宁安技术与其他复位方法的成功率和并发症，以确定其在临床实践中的作用。
