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.
