ObjectiveTo evaluate the efficacy of ultrasound guided microtraumatic treatment of acute subacromial bursitis.MethodsThe patients with shoulder pain from June 2012 to March 2014 were treated with musculoskeletal bone ultrasound examination. A total of 120 patients were diagnosed with acute subacromial bursitis, who were randomized divided into two groups:US guided injection group(ultrasound group) and palpation guided injection group(closed group). The patients in each group were injected with a mixture of 3.5 ml Betamethasone compound lidocaine mixture and 2.5 ml Sodium hyaluronate into the subacromial bursa. The outcome measures were the visual analog scale(VAS) for analyzing pain degree, the night rest pain and Constant-Murley score for detecting shoulder function, rate of secondary injection, and comprehensive effect. The VAS, the night rest pain and CMS were evaluated before, 1 day, 1 week, and 1 month after the injection.ResultsAfter treatment, the shoulder pain and function were improved. One day and 1 week after the injection, the VAS between the two groups were compared. The pain improvement in ultrasonic group was better than in the traditional group, and the difference was statistically significant(P<0.05). In the two groups, the night rest pain was relieved after treatment, and 1 day after the injection, the night rest pain in the ultrasonic group was significantly lower than that in the traditional group(P<0.05). One day, 1 week and 1 mouth after the injection, the CMS between the two groups were compared, and the improvement of CMS in the ultrasonic group was significantly better than that in the traditional group(P<0.05). The patient number with secondary injection in the ultrasonic group was 13 cases, which was significantly less than that in the closed group 45 cases(P<0.05). The recovery number of ultrasonic group was significantly better than that of the traditional group(P<0.05).ConclusionsThe ultrasound guided microtraumatic treatment of acute subacromial bursitis worked faster than traditional closed therapy. The short term curative effect and the comprehensive curative effect is better than the traditional closed treatment. The US guided subacromial injection technique is effective in guiding the needle into the subacromial bursa in patients with acute subacromial bursitis.
