Abstract
BACKGROUND: Frozen shoulder is not an uncommon disorder, and steroid injection into the glenohumeral (GH) joint is one of the most well-known approaches for the frozen shoulder. However, their results have been varied with beneficial effects or no additional advantage. With the understanding about the pathological changes taking place in frozen shoulder and the biomechanics involved, we wanted to evaluate the short- and long-term efficacy of steroid injection by a novel three-site (NTS) injection technique and compare it with the single-site injection (SSI). MATERIAL AND METHODS: This was a prospective study with 85 patients including all stages and randomized into two groups. SSI group received steroid injection through posterior approach. NTS group received the same dose of steroid in diluted doses at three sites (posterior capsule, subacromial and subcoracoid). Second sitting was repeated after 3 weeks. Both groups had received the same physiotherapy. The patients were evaluated by CONSTANT score at initial, 3 week, 6 week and 6 month. RESULTS:NTS group patients had significant pain relief and early improvement in activities of daily living ( p < 0.005). Both groups had improvement in shoulder movements but with NTS group, early near-normal scores were attained and sustained after 6 months. About 43% in SSI group could not attain near-normal levels and had relapses. CONCLUSION: The three-site approach to steroid instillation in frozen shoulder is a safe method and provides early recovery and better improvement in shoulder function with less relapses.
