Capsulolabral insertion classification reflects the variation in the relationship between the glenoid labrum and the attachment of the anteroinferior shoulder joint capsule.
Classification
This classification was originally described by Mosely and Övergaard in 1962 on cadavers 3 but has since been applied to CT and MR arthrography 4,5:
- type 1: capsule inserts into the labrum proper (most common)
- type 2: capsule inserts into the base of the labrum at the junction of the glenoid (at the glenoid fossa)
-
type 3: capsule inserts into the scapular neck (least common)
- associated with shoulder instability, and can either be congenital or secondary to anterior shoulder dislocation 3,5
Differential diagnosis
The importance for radiologists is to not confuse normal capsulolabral insertional variation with anterior labral injuries 1,2:
