Outcome of Frozen Shoulder Mobilization Under General Anesthesia

Background: Frozen shoulder, or adhesive capsulitis, is a common musculoskeletal disorder characterized by pain and restricted shoulder movement. It significantly impacts daily activities and can be associated with systemic conditions such as diabetes and thyroid disorders. While conservative treatments like physical therapy and corticosteroid injections are commonly used, mobilization under general anesthesia (MUA) is an effective alternative for patients unresponsive to these methods. However, the efficacy and long-term outcomes of MUA remain debated. Objective: This study aims to evaluate the outcomes of MUA for the treatment of frozen shoulder, specifically examining improvements in pain, shoulder function, and quality of life, as well as the factors influencing treatment success. Methods: A retrospective cohort study was conducted involving 65 patients who underwent MUA for frozen shoulder at a tertiary care hospital in Dhaka, Bangladesh, between January 2023 and January 2024. Demographic and clinical characteristics were recorded, including comorbidities and prior treatments. Patients' pre- and post-procedure pain and functional outcomes were assessed using validated tools such as the Shoulder Pain and Disability Index (SPADI), Oxford Shoulder Score (OSS), and Numeric Rating Scale (NRS). Postoperative satisfaction and complications were also documented. Results: The mean age of patients was 57.6 years, with 61.2% being female. Pre-procedure shoulder mobility assessments showed significant restrictions, including an average anteflexion of 106°, abduction of 105°, and external rotation of 24°. Post-MUA, 84% of patients reported significant pain relief, and 90% experienced improvement in daily life functioning. The median SPADI, OSS, and EQ-5D scores all indicated substantial improvement in pain, disability, and quality of life. No complications were reported, and 83.7% of patients reported sustained benefits from MUA. Conclusion: MUA is an effective treatment ..
