The intraarticular pressure during shoulder arthrography. A diagnostic aid in rotator cuff tear

The intraarticular pressure was determined in 24 shoulders during glenohumeral joint arthrography. As the contrast volume increased, the pressure stayed low in the shoulders with a tear of the rotator cuff and rose along a characteristic biphasic curve in intact shoulders. Simultaneous monitoring of the intraarticular pressure can improve the diagnostic value of arthrography.
