Palpation Versus Ultrasound-Guided Acromioclavicular Joint Intra-articular Corticosteroid Injections: A Retrospective Comparative Clinical Study

摘要: Background Primary osteoarthritis (OA) is the most common cause of pain arising from acromioclavicular (AC) joint. The true incidence unknown because differences in criteria used to define arthritis various studies. proper diagnosis AC joint OA requires a thorough physical examination, radiographic findings, and diagnostic local anesthetic injection. Objective goal this study was assess effects safety ultrasound (US) versus palpation-guided intra-articular (IA) corticosteroid injection for patients with Study design Retrospective, compared clinical study. Setting University hospital outpatient clinic. Method We retrospectively reviewed charts degenerative who had undergone US or IA between January 2012 December 2013 at our One hundred consecutive identified chart review met inclusion criteria. Patients (N = 50) guide steroid group were administered mixture 0.5% lidocaine (1 mL) triamcinolone (20 mg/mL; 0.5 contrast material (0.5 mL material. Results measured using Shoulder Pain Disability Index (SPADI), Verbal Numeric Scale (VNS) rest (VNSar), under pressure (VNSlp) ,and arm adduction test (VNSaat) space area before injections one, 3, 6 months after injections. Successful treatment occurred when obtained significant relief (as by > 50% improvement VNS score 20 point SPADI) Univariable analysis performed evaluate relationship possible outcome predictors therapeutic effect chi-square test. Logistic regression whether method, accuracy, patients' age, gender, duration disease independent successful outcome. SPADI, VNSaat, VNSlp, VNSar improved both groups. There statistically significantly greater VNSlp SPDAI VNSaat 3 US-guided as palpation group. defined found groups 3-month 6-month outcomes. Multiple logistic univariable showed that follow-up accuracy. Limitations include retrospective nature study, lack evaluation long-term , BMI less than 30 kg/m2, procedures conducted same physician. Conclusion symptomatic resulted better functional status follow-up.
