ObjectiveTo investigate the treatment effectiveness between ultrasound-guided and blind injection techniques in the treatment of subacromial bursitis.DesignA 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.ResultsThe 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).ConclusionsUltrasound 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.
