Ude Hisigi Ude Gatame

Ude-hisigi-ude-gatame - Arm Crush

Ude-gatame-jime - the arm crush. Possible the most obvious of all arm locks, this move is demonstrated in the Katame-no-kata. Tori's knee closest to uke's legs can rest on uke to prevent movement. Control of the shoulder by pressing down can dispense with this need, however. The thumb of uke should be against tori's neck so that the elbow is pressed in the correct direction.

Mune-gyaku (Chest reversal) is the name given if tori was to drive their chest forward and to the floor. Hiji-makikomi is the same lock from a standing position, with tori's arm winding around uke's arm to apply the lock to uke's elbow.

Here is a video of the application of the technique:
