Overview
Shoulder arthrography injects contrast into the glenohumeral joint under imaging guidance to evaluate labral tears and rotator cuff pathology. Fluoroscopic or ultrasound guidance ensures accurate intra articular placement. Arthrography is often combined with MRI for enhanced soft tissue visualization.
Technique
Perform sterile joint injection under fluoroscopic or ultrasound guidance and confirm intra articular contrast distribution. Use appropriate contrast type and volume for the planned imaging study. Monitor the patient for immediate adverse reactions.
Clinical Indications
Arthrogram is indicated for suspected labral tear adhesive capsulitis and occult rotator cuff pathology. It enhances detection of intra articular abnormalities when MRI alone is inconclusive. Post procedure MRI or CT arthrography provides detailed assessment.
Image Assessment
Evaluate contrast filling defects labral detachment and capsular irregularity. Assess for contrast extravasation indicating capsular rupture. Report findings to guide surgical planning and arthroscopic intervention.
