Abstract: BACKGROUND:Recent studies have shown that ultrasound-guided injection of glucocorticoids is superior to blind puncture methods. OBJECTIVE:To evaluate clinical efficacy of ultrasound-guided drug injection in the treatment of olecranon subcutaneous bursitis. METHODS:From June 2016 to September 2018, 45 patients diagnosed with obvious synovial effusion and treated with ultrasound-guided injection therapy for olecranon bursitis were included in this study. Under the guidance of ultrasound, the synovial effusion aspiration was performed and 2 ml of the compound betamethasone mixture was injected into the bursae and dressed under pressure. Ultrasound examination was performed 2 weeks after operation and the secondary fluid aspiration and drug injection treatment were performed. The depth of synovial effusion, the thickness of synovial hyperplasia and the blood flow signal were measured 4 weeks after operation to evaluate the therapeutic effect. RESULTS:After first treatment, the recurrence rate of the olecranon mass were 40%. After secondary treatment, recurrence of olecranon mass occurred in 6 of the 45 patients with a recurrence rate of 13.3%. After 4 weeks of follow-up, the depth of olecranon synovial effusion, the average thickness of synovial hyperplasia and the blood flow signal decreased significantly after treatment (P < 0.05). CONCLUSIONS:Ultrasound-guided drug injection is safe and effective in treating olecranon subcutaneous bursitis. Although the recurrence rate is high after the first treatment, the second treatment is simple and can reduce the recurrence rate. The patients have a high acceptance rate, which is worthy of clinical promotion.
