Title: Adhesive capsulitis of the shoulder: Dimensions of the rotator interval measured with magnetic resonance arthrography
Abstract: <h3>Background</h3> This study was performed to define the dimensions of the rotator interval (RI) in adhesive capsulitis using magnetic resonance (MR) arthrography preoperatively to clarify and evaluate pathology. <h3>Methods</h3> We performed a retrospective review of a series of 73 shoulders that underwent MR arthrography. The shoulders were grouped according to their diagnosis: group I comprised 47 shoulders without adhesive capsulitis; group II comprised 26 shoulders with adhesive capsulitis. Using MR arthrography, we estimated the height, base, RI area, width, RI index, and RI ratio. <h3>Results</h3> The group II shoulders differed significantly in height, base, RI area, RI index, and RI ratio from the group I shoulders. There were statistically significant differences in RI dimensions between patients with and without adhesive capsulitis of the shoulder. <h3>Conclusions</h3> Estimating the dimensions of the RI in adhesive capsulitis using MR arthrography may prove to be valuable for assessing patients preoperatively. <h3>Level of evidence</h3> Basic science study.
