GUILOFF P, Stefan; NIEDMANN E, Juan Pablo; HEBEL N, Esteban  e  VILLACRES C, Fabián. Calcific tendinitis of the rotator cuff and its lavage using ultrasound. Rev. chil. radiol. [online]. 2017, vol.23, n.3, pp.109-115. ISSN 0717-9308.  http://dx.doi.org/10.4067/S0717-93082017000300005.

Purpose: The objective of this study is to describe the technique of lavage and aspiration of calcifications under ultrasound in patients affected by this entity and to evaluate their results in the short term. Experimental design: Retrospective, descriptive study, with approval from the Ethics Committee of the Institution. Material and Methods: We performed a retrospective search of patients who underwent lavage as well as shoulder aspiration under ultrasound for calcific tendinitis at the Clínica Alemana in Santiago. 94 patients were identified between the years 2011 and 2015, of which 23 were excluded due to incomplete data. The electronic clinical record was reviewed and the data was recorded in RedCap v6 and statistical analyzes were performed using StataSE v12. Results: The sample consisted of 71 patients, the median age being 50.1 years (IQR: 41.6-57.7) and 45.1% were women. 70.4% affected the right shoulder. The mean evolution of the symptoms was 5 months (IQR: 2-24 months). 22.5% received one or more previous infiltrations and 47.9% attended kinesiotherapy. The calcifications corresponded mainly to type 1 according to the Gartner and Heyer classification (73.3%), with a median size of 14 mm on their major axis (IQR: 10-18 mm). They affected one tendon in 74.7%, two tendons in 18.3% and three tendons in 7.0%, the supraspinatus being the tendon most frequently affected (90.1%). 85.9% presented complete or significant improvement of the symptoms, only 8.5% requiring surgical resolution with arthroscopy. The final improvement had no significant association with the Gartner and Heyer type (p= 0.3), size (p= 0.16), or with the evolution time of the symptoms (p= 0.7). Conclusions: Patients with calcific tendinitis who underwent lavage and aspiration under ultrasound had, in most cases, a significant or total resolution of the symptoms at two months follow-up, with only a minor percentage requiring arthroscopy. It was not possible to identify predictors of poor evolution for this procedure. Further studies are needed to determine its advantages over medical treatment.
