Abstract

Objective: Subacromial impingement syndrome (SIS) frequently causes shoulder pain. This study aimed to (1) assess the predictive utility of quantitative dynamic subacromial ultrasound for ultrasound-guided dual-target injections and (2) compare the long-term efficacy of dual-target injections with standard subdeltoid-subacromial injections in SIS patients.

Methods: Patients with SIS received 40 mg of triamcinolone acetonide via ultrasound-guided dual-target injections (subdeltoid-subacromial bursa and long head of the biceps brachii tendon). Clinical assessments and static/dynamic ultrasound were performed at baseline and 4 weeks post-procedure. Minimal vertical acromiohumeral distance (mVAHD) was measured by tracing the humeral greater tuberosity against the acromion. A historical cohort receiving standard subdeltoid-subacromial corticosteroid injections was used for comparison.

Results: Of 90 patients receiving dual-target injections, 70 (77.7%) achieved early treatment success. An enlarged minimal mVAHD was associated with success, except during the abduction phase in the full-can posture. Among these 70 patients, 25 (35.7%) had shoulder pain recurrence requiring repeat injections, linked to a decreased mVAHD across all phases and postures. Compared to 90 patients in a historical cohort receiving standard subdeltoid-subacromial injections, the dual-target group had a significantly longer mean time to pain recurrence (309.1 ± 130.1 days vs. 267.5 ± 184.2 days, p = 0.03).

Conclusion: Dynamic ultrasound metrics, including mVAHD, predict early success and pain recurrence following dual-target injections in SIS. Dual-target injections offer a longer duration of effectiveness compared to standard subdeltoid-subacromial injections. Future research should explore the predictive value of mVAHD with deep learning algorithms and evaluate the approach in adhesive capsulitis.

Critical relevance statement: Dynamic ultrasound metrics predict early success and pain recurrence following dual-target injections in SIS, offering a longer duration of effectiveness compared to standard subdeltoid-subacromial injections.

Key points: Dynamic ultrasound metrics predict injection success and pain recurrence in impingement. Dual-target injections offer a longer duration of effectiveness than standard injections. Future research should assess deep learning's predictive value in adhesive capsulitis.

肩峰下运动指标对超声引导双靶点注射有效性的预测价值：一项纵向随访队列试验。

目的：肩峰下撞击综合征（SIS）常引起肩痛。本研究旨在(1)评估定量动态肩峰下超声对超声引导双靶点注射的预测效用；(2)比较双靶点注射与标准三角肌下-肩峰下注射在SIS患者中的长期疗效。方法：超声引导下双靶点注射曲安奈德40 mg（三角下-肩峰下滑囊和肱二头肌肌腱长头）。在基线和术后4周进行临床评估和静态/动态超声检查。最小肩肱骨垂直距离（mVAHD）通过追踪肱骨大结节对肩峰测量。一个接受标准三角肌下-肩峰下皮质类固醇注射的历史队列被用于比较。结果：90例双靶注射患者中，早期治疗成功70例（77.7%）。增大的最小mVAHD与成功相关，除了在全髋位的外展阶段。在这70例患者中，25例（35.7%）有肩部疼痛复发，需要重复注射，这与所有阶段和姿势的mVAHD下降有关。与接受标准三角肌下-肩峰下注射的90例患者相比，双靶点组疼痛复发的平均时间明显更长（309.1±130.1天vs 267.5±184.2天，p = 0.03）。结论：动态超声指标，包括mVAHD，可预测SIS双靶点注射后的早期成功和疼痛复发。与标准的三角肌下-肩峰下注射相比，双靶点注射提供了更长的有效时间。未来的研究应探索深度学习算法对mVAHD的预测价值，并评估该方法在粘连性囊炎中的应用价值。试验注册：ClinicalTrials.gov （NCT04219527）。关键相关性声明：动态超声指标预测SIS双靶点注射后的早期成功和疼痛复发，与标准三角肌下-肩峰下注射相比，提供更长的有效时间。重点：动态超声指标预测撞击后注射成功和疼痛复发。双靶注射比标准注射提供更长的有效时间。未来的研究应评估深度学习在粘连性囊炎中的预测价值。

期刊介绍： Insights into Imaging (I³) is a peer-reviewed open access journal published under the brand SpringerOpen. All content published in the journal is freely available online to anyone, anywhere! I³ continuously updates scientific knowledge and progress in best-practice standards in radiology through the publication of original articles and state-of-the-art reviews and opinions, along with recommendations and statements from the leading radiological societies in Europe. Founded by the European Society of Radiology (ESR), I³ creates a platform for educational material, guidelines and recommendations, and a forum for topics of controversy. A balanced combination of review articles, original papers, short communications from European radiological congresses and information on society matters makes I³ an indispensable source for current information in this field.
