Presentation
Two recent anterior glenohumeral joint dislocations, for MR arthrogram.
Patient Data
Injection of contrast
Injection of iodinated contrast through a 22-gauge Quincke needle and extension tubing extends into the posterior and axillary pouch portions of glenohumeral joint, confirming an intra-articular needle tip position.
The glenohumeral joint is distended with radiopaque fluid, with 8mL of the arthrogram solution injected. This image is a full exposure, as opposed to a captured image.
Case Discussion
Shown are stages of a technically successful glenohumeral arthrogram. Watching the distension of the axillary pouch is a good indication of how distended the joint is. The axillary pouch can be irregular in those with large HAGL injuries, but they will not always be apparent on fluoroscopy, even when subsequently shown on MRI.
