Summary
Double contrast computerized tomographic (CT) shoulder arthrograms are valuable for diagnosing bony, ligamentous, and cartilaginous shoulder issues. This imaging technique aids surgeons in surgical planning for conditions like instability and arthritis.
Area of Science:
- Orthopedics
- Radiology
- Medical Imaging
Background:
- Shoulder arthrography is a common diagnostic tool.
- Conventional methods have limitations in visualizing certain shoulder structures.
- Advancements in imaging technology offer potential improvements.
Purpose of the Study:
- To evaluate the diagnostic utility of double contrast computerized tomographic (CT) shoulder arthrograms.
- To compare CT arthrograms with conventional arthrograms.
- To correlate imaging findings with clinical and surgical outcomes.
Main Methods:
- Retrospective review of 55 double contrast CT shoulder arthrograms.
- Comparison with conventional arthrograms.
- Correlation of imaging findings with clinical and surgical follow-up.
Main Results:
- CT arthrograms effectively demonstrated bony, ligamentous, and cartilaginous structures.
- The technique assisted surgeons in surgical approach and procedure type selection.
- Indications for CT arthrography include instability, arthritis, deformities, and loose bodies.
- CT arthrography was less effective for rotator cuff injuries, impingement, adhesive capsulitis, and mild pain.
Conclusions:
- Double contrast CT shoulder arthrography is a useful tool for specific shoulder pathologies.
- It provides detailed anatomical information aiding surgical decision-making.
- Its utility is limited in certain conditions such as rotator cuff disease and adhesive capsulitis.
