Purpose: To evaluate the indirect magnetic resonance arthrographic findings in patients with adhesive capsulitis.
Material and methods: Twenty sets of the indirect magnetic resonance arthrographic images were included. The magnetic resonance images of ten patients who had adhesive capsulitis diagnosed by physical examination and then performed indirect magnetic resonance arthrography. The patients clinically diagnosed as adhesive capulitis were compared with those of 10 patients who did not have adhesive capsulitis. The presence of the enhancements of the subcoracoidal space, wall of the axillary recess and outer rim of the axillary recess was analyzed. The thickness of the humeral and glenoidal wall of axillary recess and the volume, height, width and depth of axillary recess was measured.
Results: The enhancement of the subcoraroidal space (n=8) and the wall (n=8) and outer rim (n=8) of the axillary recess was significantly frequent in the patients and the sensitivity/ specificity of the items were 89%/82%, 80%/80% and 88%/75%. The thickness of humeral and glenoidal wall of axillary recess in patients were 5.78 mm and 4.67 mm and these were significantly thicker than those in controls.
Conclusion: On indirect magnetic resonance arthrography, the enhancement of the subcoraroidal space and axillary recess and increased thickness of the wall of the axillary recess are the useful diagnostic imaging characteristics.
