Abstract
Compare intraarticular pressure of the glenohumeral joint in patients with and without shoulder instability after a volume-limited arthrogram. Patients aged 18-45 years with shoulder instability or pain were included. After injecting 10 cc of contrast-mixture, intraarticular pressure was recorded using an arterial-line pressure-transducer connected to a portable monitor. 14/16 (86%) patients were included - 7/14 (50%) had instability. Post-injection pressure measurement averaged 59.9 ± 44.0 mmHg (range 15-181). Instability patients averaged 60.8 ± 37.6 (range 15-117) versus 41.9 ± 14.0 mmHg (range 30-64) for non-instability (p > 0.1). Glenohumeral pressure measurements are variable when utilizing standardized volume-limited arthrograms.
