On a MRI of the shoulder with a arthrogram, if you can't do the end part of the MRI where you lift your arm over your head(because of the pain being too bad), what may they not see on the report? A torn labrum? Also would that cause severe upper bicep pain?
That position, known as the ABER, position is necessary to view the labrum well. However, usually the radiologist will inject anesthesia along with the dye to make positioning of your arm less painful.
While labral problems will cause biceps pain. This does not occur after successful biceps tenotomy.
