Purpose : To analyze the outcome after barbotage and subacromial corticosteroid injection in acute pain attack with calcific tendinitis of the shoulder. Materials and Methods : Twenty-two patients with acute calcific tendinitis were analyzed with average follow-up of Twenty-two months. The shape and size of calcific deposits were classified. The outcome was assessed by UCLA shoulder score and pain in visual analogue scale(VAS). Results : Sixteen patients(73%) had permanent relief of pain. The results assessed by UCLA score were excellent in fourteen patients and good in two patients. Average VAS for pain was 0.6 ± 0.73 (range:0-2). No complication was enccpuntered, but six patients underwent surgical treatment due to lack of improvement or recurrence. Conclusion : Barbotage as a primary treatment in acute calcific tendinits of the shoulder is simple and effective, and therefore should be tried before surgical intervention.
