In combat sports, a spinal lock is a multiple joint lock applied to the spinal column, which is performed by forcing the spine beyond its normal ranges of motion. This is typically done by bending or twisting the head or upper body into abnormal positions. Commonly, spinal locks might strain the spinal musculature or result in a mild spinal sprain, while a forcefully and/or suddenly applied spinal lock may cause severe ligament damage or damage to the vertebrae, and possibly result in serious spinal cord injury, stroke, or death.[citation needed] Spinal locks and cervical locks are forbidden in all gi competitions, IBJJF Brazilian jiu-jitsu competitions,[1] amateur mixed martial arts (MMA),[2][3] multiple forms of no Gi jiu-jitsu,[4] judo,[5] and other martial arts.[6] However, professional MMA, some no gi Brazilian jiu-jitsu competitions[7] and one gi & no gi promotion (grappling industries) do permit spinal locks and, particularly, neck cranks, and such moves are trained in various MMA and Brazilian jiu-jitsu schools.
Spinal locks can be separated into two categories based on their primary area of effect on the spinal column: spinal locks on the neck are called neck cranks, and locks on the lower parts of the spine are called spine cranks.
