RESUMEN
Background@#To evaluate the demographics, clinical and radiographic features of calcific tendinitis of the shoulder in the Korean population, specifically focusing on the incidence of coexisting rotator cuff tear. @*Methods@#Between October 2014 and January 2015, we performed a prospective multicenter study with 506 patients from 11 training hospitals in Korea. We collected data of demographics and radiographic analysis based on simple radiographs, clinical assessments based on visual analog scale (VAS) and the American Shoulder Elbow Surgeons (ASES) score, and treatment modalities that are used currently. We also evaluated coexisting rotator cuff tear by ultrasonography (US) or magnetic resonance imaging (MRI) images. @*Results@#There were 402 female patients (79%) with mean age of 55 years (range, 31–87 years). Mean duration of symptoms was 16 months. Mean size of calcific materials was 11.4 mm (range, 0–35 mm). Mean value of VAS and ASES scores were 6.5 (range, 1–10) and 47 (range, 8–95), respectively. Of 383 patients (76%), 59 (15%) had rotator cuff tear including 15 full-thickness tears on US or MRI. Patients with rotator cuff tears were significantly associated with older age, recurrent symptoms, menstrual disorders in females, and having undergone calcification removal surgery and rotator cuff repair (all p<0.05). @*Conclusions@#This study reported demographic, radiographic, and clinical features of calcific tendinitis of the shoulder in Korean population, which were not different from those of Western population. Coexisting rotator cuff tear was found with 15% incidence in this large series, suggesting that further radiographic study to evaluate rotator cuff tear might be needed in some calcific tendinitis patients of older age and presenting with recurrent symptoms.

RESUMEN
BACKGROUND@#This study was undertaken to evaluate early clinical outcomes of ultrasound-guided suprascapular nerve block (SSNB) using a proximal approach, as compared with subacromial steroid injection (SA).@*METHODS@#This retrospective study included a consecutive series of 40 patients of SSNB and 20 patients receiving SA, from August 2017 to August 2018. The visual analogue scale (VAS), American Shoulder Elbow Surgeon's score (ASES), University of California, Los Angeles score (UCLA), the 36 health survey questionnaire mental component summary (SF36-MCS), physical component summary (PCS), and range of motion (forward elevation, external rotation, and internal rotation) were assessed for clinical evaluations.@*RESULTS@#Compared with the baseline, VAS, and ranges of motion in the SSNB group significantly improved at the 4-week follow-up (VAS scores improved from 6.7 ± 1.6 to 4.3 ± 2.4, p<0.001; all ranges of motion p<0.05), while other variables showed no statistically significant differences. All clinical variables were significantly improved in the SA group (p<0.05). However, all clinical scores at the 4-week follow-up showed no significant difference between groups.@*CONCLUSIONS@#Ultrasound-guided SSNB using proximal approach provides significant pain relief at 4-weeks after treatment, with statistically significant difference when compared with SA, suggesting that SSNB using proximal approach is a potentially useful option in managing shoulder pain. However, in the current study, it was less effective in improving shoulder function and health-related quality of life, compared with SA.
