In this work, we modified the conventional double-needle approach by incorporating a closed-circuit irrigation system and assessed the procedure\u2019s clinical and radiological outcomes. We enrolled prospectively 24 patients (10 males; median age 54 years, IQR: 50\u201362) with painful calcific tendonitis of the shoulder between October 2023 and March 2024. All patients had a calcification &gt; 5 mm treated with ultrasound-guided closed-circuit irrigation. Radiography, ultrasound evaluation, and OSS and SPADI clinical questionnaires were administered before the treatment and 3 months after. After the procedure, there was a significant reduction in the size of the calcifications (12 mm, IQR: 10\u201320 mm vs. 5.5 mm, IQR: 2\u201310 mm; p &lt; 0.001). After the procedure, none of the patients experienced infections, while two developed bursitis. Three months after the procedure there were significant improvement in the OSS (16.5, IQR: 10\u201323 vs. 32, IQR: 36\u201345.5; p &lt; 0.0001) and reduction in SPADI scores: pain (88, IQR: 74\u201395 before vs. 13, IQR: 4\u201324; p &lt; 0.0001), disability (72, IQR: 60\u201390 before vs. 8, IQR: 4\u201320; p &lt; 0.0001), and total score (78, IQR: 66\u201391 before vs. 11, IQR: 4\u201320; p &lt; 0.0001). The closed-circuit double-needle irrigation for calcific tendinopathy of the shoulder is an effective treatment that improves both shoulder pain and function with a very low risk of short-term complications.<\/jats:p>","DOI":"10.3390\/life15081302","type":"journal-article","created":{"date-parts":[[2025,8,18]],"date-time":"2025-08-18T07:53:12Z","timestamp":1755503592000},"page":"1302","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Clinical and Radiological Outcomes of Ultrasound-Guided Closed-Circuit Irrigation of Calcific Tendinitis of the Shoulder: A Prospective Study"],"prefix":"10.3390","volume":"15","author":[{"ORCID":"https:\/\/orcid.org\/0009-0000-8818-1624","authenticated-orcid":false,"given":"Andrea","family":"De Grandis","sequence":"first","affiliation":[{"name":"Institute of Radiology, Department of Medicine-DIMED, University of Padova, Via Giustiniani 2, 35128 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-6721-3946","authenticated-orcid":false,"given":"Carlo","family":"D\u2019Alessandro","sequence":"additional","affiliation":[{"name":"Institute of Radiology, Department of Medicine-DIMED, University of Padova, Via Giustiniani 2, 35128 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0001-1694-4036","authenticated-orcid":false,"given":"Giovanni","family":"Sussan","sequence":"additional","affiliation":[{"name":"Institute of Radiology, Department of Medicine-DIMED, University of Padova, Via Giustiniani 2, 35128 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Alberto","family":"Crim\u00ec","sequence":"additional","affiliation":[{"name":"Orthopedics and Orthopedic Oncology Unit, Department of Surgery, Oncology and Gastroenterology DiSCOG, University of Padova, Via Giustiniani 2, 35128 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4239-4859","authenticated-orcid":false,"given":"Lucrezia","family":"Tognolo","sequence":"additional","affiliation":[{"name":"Rehabilitation Unit, Department of Neuroscience, University of Padova, 35122 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daniele","family":"Coraci","sequence":"additional","affiliation":[{"name":"Rehabilitation Unit, Department of Neuroscience, University of Padova, 35122 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0361-4898","authenticated-orcid":false,"given":"Stefano","family":"Masiero","sequence":"additional","affiliation":[{"name":"Rehabilitation Unit, Department of Neuroscience, University of Padova, 35122 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roberto","family":"Ragazzi","sequence":"additional","affiliation":[{"name":"Radiology Department, Ospedale dell\u2019Angelo Mestre, ULSS 3 Serenissima, Via Paccagnella 11, 30174 Venezia, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2020-9365","authenticated-orcid":false,"given":"Emilio","family":"Quaia","sequence":"additional","affiliation":[{"name":"Institute of Radiology, Department of Medicine-DIMED, University of Padova, Via Giustiniani 2, 35128 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6822-1430","authenticated-orcid":false,"given":"Filippo","family":"Crim\u00ec","sequence":"additional","affiliation":[{"name":"Institute of Radiology, Department of Medicine-DIMED, University of Padova, Via Giustiniani 2, 35128 Padova, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,8,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"130","DOI":"10.11138\/jts\/2014.2.3.130","article-title":"Calcific tendinitis of the shoulder","volume":"2","author":"Pulcinelli","year":"2014","journal-title":"Joints"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"1582","DOI":"10.1056\/NEJM199905203402011","article-title":"Calcific Tendinitis of the Shoulder","volume":"340","author":"Speed","year":"1999","journal-title":"N.
