Pain & resistance in patients with adhesive capsulitis during contrast material injection phase of MR arthrography.
OBJECTIVE
Adhesive capsulitis of the shoulder is a condition of unknown aetiology that results in the development of restricted active and passive glenohumeral motion. It has been reported that magnetic resonance (MR) imaging is useful in diagnosing adhesive capsulitis. We carried out this study to assess how pain and/or resistance during contrast material injection affects the diagnosis of adhesive capsulitis on magnetic resonance (MR) arthrography.


METHODS
The study included MR arthrography examinations of 21 patients with a diagnosis of adhesive capsulitis. The control group consisted of 20 patients who presented clinically with rotator cuff tear. The pain (visual analog scale, VAS), resistance to injection and the amount of contrast material that could be injected during injection phase of MR arthrography was assessed and compared between groups.


RESULTS
The patients in adhesive capsulitis group (mean VAS score 66.5+/-25.5) experienced more pain when compared with the control group (mean VAS score 34.9+/-27.7, P<0.001). A statistically significant difference (P<0.001) in terms of the amount of the injected fluid (4.3+/-2.6 ml for adhesive capsulitis group, and 10.9+/-4.1 ml for control group) was seen into the joint cavity. Resistance to injection was significantly more (P<0.001) in patients with adhesive capsulitis when compared to control group.


CONCLUSIONS
Experience of pain during injection, a decreased amount of contrast material injected and resistance to injection in patients during injection phase of MR arthrography may suggest adhesive capsulitis.
