- Extensor compartment of the wrist
The forearm extensor tendonspass under the extensor retinaculum at the level of the wrist. The ligament is divided into six extensor compartments, separated by fibrous septa passing to the bones of the forearm 2.
Summary
The compartments in order from radial to ulnar are:
-
1st compartment:
-
2nd compartment:
-
3rd compartment (separated from compartment 2 by Lister's tubercle):
-
4th compartment:
-
5th compartment:
-
6th compartment (runs in the groove of the ulnar head):
