- Abstract
<bold>Objectives: </bold>Rotator cuff calcific tendinopathy (RCCT) with intraosseous extension is a rare complication of tendinous and peritendinous involvement. The purpose of our study is to evaluate the outcome of ultrasound-guided percutaneous irrigation of calcific tendinopathy (US-PICT) in patients with intraosseous involvement.<bold>Materials and Methods: </bold>From January 2011 to June 2014, patients with a clinical and imaging diagnosis of RCCT were prospectively categorised in two groups based on imaging findings: group A (10 patients) with intraosseous RCCT and group B (control group 35 patients) without osseous involvement. US-PICT followed by subacromial injection was applied to all patients in groups A and B. During a 1-year follow-up, treatment outcome in terms of pain and functional improvement was evaluated at 3 weeks, 3 months, 6 months, and 1 year, with the use of a four-grade scale. The study has been approved by our hospital's ethics committee.<bold>Results: </bold>Mean improvement scores of group A were significantly lower than those of group B at all time points (p < 0.0001). Improvement of group B was noted mainly within the first 3 months post-treatment (p = 0.016).<bold>Conclusion: </bold>Outcomes of ultrasound-guided treatment in cases of RCCT with intraosseous extension are significantly less favourable than in purely tendinous or peritendinous disease.
