Background: Frozen shoulder (FS) is usually a self-limiting but debilitating condition, with pain and limitation in range of motion of the involved shoulder which may peak at 3-6 months. Early shoulder exercises are painful but important to achieve full range of motion. So early interventions like hydrodilatation (HD)with suprascapular nerve blocks (SSNB) when performed prior to physical therapy can alleviate the severe pain, inflammation and make rehabilitation easy. This study aims to know the effect of SSNB on shoulder hydrodilatation, procedural comfort, and effect on pain and disability scores at 12 weeks follow up. Methods: Our study was a retrospective observational study which included 30-60 years old patients, diagnosed with stage 2 of FS who had underwent intervention. Group SSN+HD received suprascapular nerve block with local anesthetic, followed by hydrodilatation whereas Group HD no nerve block was given. The functional outcome was evaluated by Shoulder Pain and Disability Index (SPADI) score and shoulder active range of motion (ROM) measured at 2 weeks, 6 weeks and 12 weeks. Intraprocedure VAS score was measured. Result: The results of this study show that SSN block provides better intraprocedure VAS (3.8 vs 8.3 p< 0.001) and ease of HD and manipulation than HD alone .At the end of 12 weeks, both the groups improved significantly from the baseline SPADI score but SSN+HD group had significantly less scores ( p < 0.001). The ROM for active abduction ( p< 0.008) and forward flexion ( p < 0.001) was also improved significantly in SSN+HD group. Conclusion: Both SSNB+HD and HD are effective in reducing pain and improving shoulder function. However, augmentation with SSNB has significantly better results.
