The effects of combining extracorporeal shock waves with injection of the supraspinatus bursa in the treatment of non-calcified tendinitis of the supraspinatus tendon / 中华物理医学与康复杂志

ABSTRACT

Objective:To observe any differential clinical effect of supplementing ultrasound-guided injection of the subacromial bursa with extracorporeal shock wave stimulation in the treatment of non-calcific tendinitis of the supraspinatus tendon.Methods:Sixty individuals with non-calcific tendinitis of the supraspinatus tendon were randomly divided into an observation group and a control group, each of 30. Both groups received routine medication, health education and extracorporeal shock wave treatment, but the observation group additionally received ultrasound-guided injection of compound betamethasone injection plus 2% lidocaine intothe subacromial bursa. The treatment′s effect was evaluated using a visual analogue scale (VAS) and the UCLA shoulder rating scale (UCLA). Absorption of hydrops in the subacromial bursa was assessed using ultrasound imaging after 7 and 14 days of the treatment.Results:After 7 and after 14 days the average VAS scores had decreased significantly, while the average UCLA score had increased significantly. At both time points the observation group′s average results were significantly better than those of the control group. The total effective absorption rate of hydrops in the subacromial bursa in the observation group (80.0%) was significantly higher than in the control group after 14 days of treatment.Conclusion:Extracorporeal shock wave stimulation combined with injection of the subacromial bursa can effectively alleviate the pain of non-calcific tendinitis of the supraspinatus tendon, improve joint function, and promote the absorption of hydrops.
