Abstract: Introduction: Adhesive capsulitis (frozen shoulder) affects 2% to 5% of the adult population. The accuracy rate of intraarticular injections at shoulder was 52.4% in a study by Hegedus et al. Periarticular placement may allow sufficient steroid to diffuse into an adjacent joint and so achieve a partial response. Issues that remain to be clarified include whether the accuracy of needle placement and anatomical site influences efficacy. Due to these uncertainties we decided to do this study.
Materials and Methods: A Prospective study analyzing the functional outcome of 34 cases of Single Periarticular injection of Steroid at Shoulder for Periarthritis of shoulder was conducted. The surgeon confirmed with C-arm image that the needle was periarticular and ‘not intraarticular’ and instilled the injection of 40 mg of Triamcinolone acetate. Findings were recorded and Outcomes were measured before the injection and during all the followups. Statistical Evaluation was made and Conclusions were arrived at.
Results: There were 34 patients (36 shoulders) treated with periarticular injection of steroid. The improvement in abduction was 38.11 degrees with p value 0.001, which is statistically significant. Improvement in flexion was 39.19 degrees. The improvement in Constant score was 21.22 with p value 0.001 which is statistically significant.
Conclusion: A single Periarticular injection of steroid for Periarthritis of shoulder provides good improvement in Abduction and Flexion. Its results are the same as with intraarticular injections. Blind injections without fluoroscopic guidance will give the same results as those with fluoroscopic guidance.
