Comparison of the Treatment Efficacy of Suprascapular Nerve Block and Intraarticular Shoulder Injection Techniques in Patients Diagnosed With Adhesive Capsulitis

Objective: We aim to compare the efficiency of the ultrasonography-guided suprascapular nerve block (SSNB) and ultrasonography-guided intra-articular shoulder injection (IAI) techniques in terms of pain and functional status in the treatment of adhesive capsulitis. Design: 60 patients with adhesive capsulitis were divided into two groups: SSNB and IAI. Both groups received an injection of 1 ml of 40 mg of triamcinolone acetonide and 9 ml of 0.5% bupivacaine hydrochloride. The patients' Shoulder Pain and Disability Index (SPADI) scores, shoulder active and passive range of motions (ROM), and visual analog scale (VAS) scores were evaluated before and after the injection in the 1st week, 4th week, and 12th week.
