A Three-arm Randomized Control Trial Comparing Efficacy of Hydrodistension Hydrodistension With Suprascapular Nerve Block And Suprascapular Nerve Block Alone In Patients With Stage II and III (Hannafin And Chaia Staging) Adhesive Capsulitis

Adhesive capsulitis is a common shoulder disorder characterized by pain and restricted range of motion. Various treatments exist, but the most effective approach remains uncertain. This randomized controlled trial will compare the functional outcome of three treatment methods for Hannafin and Chiaia stage II and III adhesive capsulitis of the shoulder. The study will be conducted in the Department of Orthopaedics at AIIMS Bibinagar over a period of two years from June 2025 to June 2027. A total of 54 adult patients meeting Zuckerman diagnostic criteria will be enrolled and randomly allocated into three equal groups. Group one will receive ultrasound guided hydrodistension of the glenohumeral joint with corticosteroid and normal saline. Group two will receive hydrodistension combined with suprascapular nerve block, and group three will receive suprascapular nerve block alone. All participants will perform a supervised shoulder exercise program after the intervention. Pain will be measured using the Visual Analogue Scale, shoulder function by the Shoulder Pain and Disability Index and Quick DASH scores, and range of motion by goniometer at baseline and at day 2, week 2, week 4, week 8, and week 12. Data will be analyzed using appropriate statistical tests with a significance level of 0.05. The trial aims to identify which treatment provides the best pain relief, range of motion, and functional recovery in adhesive capsulitis.
