The geyser sign and torn rotator cuff: clinical significance and pathomechanics.
The geyser radiographic sign on shoulder arthrogram is characterized by leakage of dye from the glenohumeral joint into the subdeltoid bursa. The dye outlines the acromioclavicular joint. It is usually an indication of a full-thickness cuff tear of long duration. The clinical occurrence and pathomechanics of this finding indicate that repair is generally difficult.
