Extensor Carpi Ulnaris Subluxation (Snapping ECU)

The extensor carpi ulnaris tendon passes through a groove on the ulna bone of the forearm where it is held in position by a sheath of connective tissue. Deficiency of this sheath can lead to dislocation or subluxation of the tendon causing pain and snapping with wrist movement.
