Glenohumeral arthrogram injection (fluoroscopic guided)

Case contributed by Dr Dai Roberts

Presentation

Two recent anterior glenohumeral joint dislocations, for MR arthrogram.

Patient Data

Age: 30
Gender: Male
Fluoroscopy

Injection of iodinated 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.

Fluoroscopy

Post administration of injectate

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.
