Shoulder arthrogram injection (fluoroscopic guided)

Case contributed by Dr Dai Roberts


Anterior glenohumeral joint instability. For MRI arthrogram injection.

Patient Data

Age: 20 years
Gender: Male

Injection of iodinated contrast

A 22-gauge Quincke needle targets the inferomedial humeral head, with the injection of iodinated contrast confirming an intra-articular needle position by extending into the inferior portion of the joint and axillary pouch.


Post administration of injectate

The arthrogram injectate distends the joint.  A small amount of iodinated contrast is included in the arthrogram injectate (in the 20mL syringe) to aid this assessment.  

Case Discussion

Shown is a technically successful posterior shoulder / glenohumeral joint arthrogram injection. Patient positioning is more technical compared to the anterior approach where the patient would lie supine with their arm by their side and hand supinated. In a posterior approach, the patient is prone and with the use of a wedge, they are angled at around 40 degrees from the table, therefore making the oblique glenohumeral joint in line with the x-ray beam 1
