Spine

First Ordering: Intended Target of Attack

Locks applied to the Spine 

Andrew's Notes: Spinal manipulations are an order of magnitude more dangerous that any other Lock on this list, and are banned as a result from many competitions. Particularly spinal manipulation of the neck, can result in life alter injuries such as paralysis, and even  ☠️death ☠️.  It is my opinion that they should be practiced on a resisting opponent, during an open mat, and competitors should be very weary, when the result allows for them. Where practiced, I recommend a compliant Uke, who had been explained the technique, and is ready and prepared to tap prior to any significant application of breaking force.
