Abstract

Rationale and objectives: While ultrasound-guided percutaneous irrigation for painful calcific tendinopathy (US-PICT) is the treatment of choice for the rotator cuff, there is a lack of knowledge regarding the treatment of this condition with atypical location. The purpose of our study is to assess if US-PICT can be applied safely and successfully in atypical sites, outside of the rotator cuff.

Materials and methods: We retrospectively reviewed the US-PICT performed outside the rotator cuff, in the last 5 years in a single institution. A total of 16 patients have been included in this study. We collected the values of the numerical rating scale (NRS) for pain pre- and post-procedure (7 days and 3-month follow-up). Moreover, we assessed the imaging studies available pre- and post-procedure (ultrasound and plain radiography) to assess complications.

Results: In all the 16 patients (10F, 6 M; mean age 50.2; range 24-65-year-old), no complications have been observed during and after the procedures. The mean pain NRS before treatment was 8.7 (range 10-6) and dropped to 1.1 (6-0) after 1 week as well after 3 months 1.1 (6-0). The NRS pain reduction from baseline resulted to be statistically significant after 7 days and 3 months (p < 0.001).

Conclusion: Our results suggest the safety and efficacy of this procedure, underlining the great potential of US-PICT applied even in different atypical locations.
