This study aimed to evaluate an innovative anterolateral approach using portable ultrasound, comparing the accuracy and safety of portable ultrasound-guided, conventional ultrasound-guided, and landmark-based blind injection techniques.
In this single-centre, prospective, randomised controlled trial, 117 patients with hip pain were randomly assigned to three groups: landmark-based blind injection (n = 39), conventional ultrasound-guided injection (n = 39), and portable ultrasound-guided injection (n = 39). Each patient received a unilateral injection of 2.5 ml hyaluronic acid and 1 ml betamethasone via the anterolateral approach, using parameters optimized from previous research. Primary endpoints included success and accuracy rates, while secondary endpoints comprised post-injection visual analogue scale (VAS) pain scores, procedure time, puncture depth, and complications.
The portable ultrasound group achieved 100% success and accuracy rates, comparable to the conventional ultrasound group, whereas the blind group showed lower success (87.2%) and accuracy (79.4%) rates. Post-injection VAS pain scores were significantly lower in the portable ultrasound group (1.95, SD 0.99) compared with the blind group (2.95, SD 1.61; p = 0.007) and similar to those in the conventional ultrasound group (2.41, SD 1.27; p = 0.337). Procedure times were comparable across all groups, and no significant differences in puncture depth were observed. Importantly, no injection-related complications were reported.
Portable ultrasound-guided injections via the anterolateral approach demonstrate accuracy and safety comparable to conventional ultrasound-guided injections. Additionally, the portable device offers advantages in portability, reduced space requirements, and cost-effectiveness, thereby enhancing clinical utility in outpatient settings.
本研究旨在评估一种使用便携式超声的创新前外侧入路，比较便携式超声引导、传统超声引导和基于体表标志的盲注技术的准确性和安全性。
在这项单中心、前瞻性、随机对照试验中，117例髋关节疼痛患者被随机分为三组：基于体表标志的盲注组（n = 39）、传统超声引导注射组（n = 39）和便携式超声引导注射组（n = 39）。每位患者通过前外侧入路接受2.5毫升透明质酸和1毫升倍他米松的单侧注射，使用从先前研究中优化的参数。主要终点包括成功率和准确率，次要终点包括注射后视觉模拟量表（VAS）疼痛评分、操作时间、穿刺深度和并发症。
便携式超声组的成功率和准确率均达到100%，与传统超声组相当，而盲注组的成功率（87.2%）和准确率（79.4%）较低。与盲注组（2.95，标准差1.61；p = 0.007）相比，便携式超声组注射后的VAS疼痛评分显著更低（1.95，标准差0.99），且与传统超声组（2.41，标准差1.27；p = 0.337）相似。所有组的操作时间相当，穿刺深度未观察到显著差异。重要的是，未报告与注射相关的并发症。
通过前外侧入路进行便携式超声引导注射显示出与传统超声引导注射相当的准确性和安全性。此外，便携式设备在便携性、减少空间需求和成本效益方面具有优势，从而提高了门诊环境中的临床实用性。
