Approach Considerations

No specific laboratory studies have been helpful in the evaluation or treatment of deltoid fibrosis. Diagnostic imaging (see Imaging Studies) is performed for initial evaluation. No other specific tests have been shown to be beneficial. Electromyography (EMG) may have research value, but it is not used routinely for patient evaluation in this setting. [26]  The histology of deltoid fibrosis shows dense fibrous tissue with some atrophied muscle fibers. [6, 27]


Imaging Studies

Plain radiographs are used initially to evaluate the glenohumeral and scapulothoracic mechanics. Fluoroscopic examination may follow if results are inconclusive.

If fluoroscopic examination is also inconclusive, computed tomography (CT) may be performed to evaluate any bone or joint abnormalities. CT scans provide a more comprehensive view of the glenohumeral joint than do plain films or fluoroscopic examination.
