Capitellar MRI staging to estimate stability

Stage	Characteristics	Stability
1	Capitellum is normally shaped with several spotted areas of high signal intensity lower than that of cartilage	Stable
2	Several spotted areas of higher intensity than that of cartilage	Stable
3	Discontinuity and non-circularity of the chondral surface signal of the capitellum and no high signal interface apparent between the lesion and the floor	Unstable
4	Lesion separated by a high intensity line in comparison with cartilage	Unstable
5	Capitellar lesion displaced from the floor or defect of the capitellar lesion noted	Unstable
