US-guided percutaneous treatment and physical therapy in rotator cuff calcific tendinopathy of the shoulder: outcome at 3 and 12 months.

The objectives of this study were to monitor the results of ultrasound (US)-guided percutaneous treatment of calcific tendinopathy of the shoulder at 12 months (T12) after treatment (T0) as well as to verify the possible relations between some pre- and post-procedural variables with the clinical outcome at T12. Forty-seven patients (26 female and 21 male) were enrolled in the study. Patients’ approval and written informed consent were obtained. Symptoms were assessed by Constant Shoulder Score (CSS) at T0 and T12. Thirty of these also underwent a CSS control at 3 months (T3). The treatment efficacy was statistically tested for relation with location and type of calcification, characteristics of the tendon and subdeltoid bursa, impingement, and rehabilitation treatments. There was a significant increase in the average CSS value between T0 and T12 (40.7 vs. 75.3). The variables analysed did not show a statistically significant effect on the outcome at T12. A link was noticed only between patients’ increasing age and score improvement, particularly among female subjects.

US-guided treatment of calcific tendonitis is a viable therapeutic option. No pre- or intra-procedural parameters emerged which might help in predicting the outcome, apart from patients’ needs in everyday life.
