To investigate the treatment effectiveness between ultrasound-guided and blind injection techniques in the treatment of subacromial bursitis.
A total of 40 patients with sonographic confirmation of subacromial bursitis were recruited into this study. These patients were divided into blind and ultrasound-guided injection groups. The shoulder abduction range of motion was compared before injections and 1 wk after the completion of injections in both groups.
The shoulder abduction range of motion before injection in the blind injection group was 71.03 +/- 12.38 degrees and improved to 100 +/- 18.18 degrees 1 wk after the injection treatments. However, the improvement did not reveal significant statistical differences (P > 0.05). The shoulder abduction range of motion before injection in the ultrasound-guided injection group was 69.05 +/- 14.72 degrees and improved to 139.29 +/- 20.14 degrees 1 wk after the injection treatments (P < 0.05).
Ultrasound may be used as an adjuvant tool in guiding the needle accurately into the inflamed subacromial bursa. The ultrasound-guided injection technique can result in significant improvement in shoulder abduction range of motion as compared with the blind injection technique in treating patients with subacromial bursitis.
探讨超声引导注射技术与盲目注射技术治疗肩峰下滑囊炎的疗效。
本研究共纳入40例经超声确诊为肩峰下滑囊炎的患者。这些患者被分为盲目注射组和超声引导注射组。比较两组患者注射前及注射完成后1周的肩关节外展活动度。
盲目注射组注射前肩关节外展活动度为71.03±12.38度，注射治疗1周后改善至100±18.18度。然而，改善情况未显示出显著的统计学差异（P>0.05）。超声引导注射组注射前肩关节外展活动度为69.05±14.72度，注射治疗1周后改善至139.29±20.14度（P<0.05）。
超声可作为一种辅助工具，将针头准确引导至发炎的肩峰下滑囊。与盲目注射技术相比，超声引导注射技术在治疗肩峰下滑囊炎患者时可使肩关节外展活动度得到显著改善。
