Background: Shoulder pain is the third most common type of musculoskeletal disorder and rotator cuff (RC) tendinopathy is the most frequent diagnosis. Ultrasound is the most preferable guidance tool for diagnostic and interventional purposes. The aim of this study is to compare the effectiveness of the prolotherapy injection with corticosteroid injection in patients with RC dysfunction.
Materials and methods: Thirty to sixty-five-year-old patients with chronic RC disease were divided into two groups. Ultrasound-guided dextrose prolotherapy of supraspinatus tendon was done for one group and ultrasound-guided corticosteroid injection in the subacromial bursa was done for the other groups. Visual analog scale (VAS) and Shoulder Pain and Disability Index (SPADI) were evaluated for both groups at baseline, 3 and 12 weeks after injections.
Results: Thirty-three patients were included in the result. Both the groups showed significant improvement in VAS and SPADI scores in 3 and 12 weeks after injections compared with preinjection times with no difference between two groups neither in 3 weeks nor in 12 weeks after injections.
Conclusion: Both ultrasound-guided dextrose prolotherapy and CS injections are effective in the management of RC-related shoulder pain in both short-term and long-term with neither being superior to the other. Therefore, prolotherapy may be a safe alternative therapy instead of corticosteroid injection due to lack of its side effects.
