Abstract

Adhesive Capsulitis of shoulder (AdCS) is a treatment dilemma for surgeons. Intraarticular Corticosteroid Injection (IACI) has shown only short-term benefit in improving shoulder-related disability. Suprascapular nerve block (SSNB) has shown promise in trials in reducing chronic shoulder pain. Thus a RCT was conducted to compare the efficacy of SSNB versus IACI in the treatment of AdCS. 86 patients with AdCS were divided into SSNB and IACI groups by block randomization. SSNB group received single Suprascapular Nerve Block with 10ml of 0.5% Bupivacaine while IACI group received single injection of 40mg Triamcinolone and 1ml 2% Lignocaine in the shoulder; both followed by physiotherapy and followed-up and evaluated with SPADI and modified Constant scores at 1, 6 and 12 weeks. Statistically significant improvements occurred in both groups. At 12 weeks, the SPADI and Con-stant score for SSNB improved to 9.62±10.07 and 36.95±3.43 respectively (p<0.001); and for IACI improved to 11.65±5.56 and 35.07±3.32 respectively (p <0.001). The difference in the scores between the 2 groups at 1st and 6th week was insignificant, but was statistically significant in favour of SSNB at 12 weeks (p=0.002). 1. Thus, from the present study it can be concluded that both Suprascapular Nerve Block and Intra-articular Corticosteroid injection are effective mo-dalities of treatment for Adhesive Capsulitis of the shoulder. 2. Suprascapular Nerve Block increased patients' pain tolerability for effective mobilization, the effect be-ing persistent even at 12 weeks following injection. 3. It was safer than Intra-articular Corticosteroid in-jection with less incidence of adverse effects in our study and the literature. 4. It is an easy-to-perform outpatient procedure, with minimal chance of infection and other complications. 5. In light of the above, we may recommend Su-prascapular Nerve Block as the initial procedure of choice in patients with Adhesive Capsulitis of Shoulder.
