Reliability of non-imaging-guided glenohumeral joint injection through rotator interval approach in patients undergoing diagnostic MR arthrography.
OBJECTIVE
The purpose of our study is to review the accuracy of our method of non-imaging-guided anterior glenohumeral gadolinium contrast injection targeting the rotator interval in 100 consecutive patients.


METHODS
One hundred consecutive community-referred patients at our MRI facility underwent non-imaging-guided glenohumeral contrast injection targeting the rotator interval, with no patients excluded on the basis of expected diagnosis. The studies were then retrospectively reviewed for accuracy of injection based on patient factors and diagnosis.


RESULTS
This method was 99% accurate in our study, regardless of diagnosis.


CONCLUSIONS
The relative ease, efficiency, reproducibility, and accuracy of this method of non-imaging-guided anterior glenohumeral injection make it the method of choice at our institution, and we believe this technique merits consideration for more widespread utilization.
