The Samilson-Prieto classification is preferable for osteoarthritis of the glenohumeral joint.[1]
| Grade | Description |
|---|---|
| Mild | Exostosis of inferior humerus and/or glenoid measuring less than 3 mm |
| Moderate | Exostosis of inferior humerus and/or glenoid measuring 3–7 mm, and slight irregularity of the joint |
| Severe | Exostosis of inferior humerus and/or glenoid measuring more than 7 mm in height as well as sclerosis and narrowing of the joint space (normal joint space is 4–5 mm).[3] |
Differential diagnosis
Rheumatoid arthritis, also having joint space narrowing, but also periarticular joint erosions (arrows)
