Can the Boston Crab Actually Break a Spine? Combat Experts Weigh In
By Alexander Ross
Q1: Can a Boston crab permanently paralyze someone?
Yes. If applied with maximum downward force against someone who cannot tap or whose cries are ignored, the severe hyperextension can cause catastrophic bilateral facet joint dislocation or severe disc extrusion into the spinal cord and cauda equina, leading to permanent neurological damage or lower-body paralysis.
Q2: Why is the Boston crab legal in pro wrestling but rare in the UFC?
In professional wrestling, performers actively cooperate to distribute weight safely and protect each other's spines. In the UFC, opponents do not cooperate; catching both legs of a defending mixed martial artist without getting kicked, swept, or leg-locked is nearly impossible against trained competition.
Q3: What should you do if someone catches you in a Boston crab during sparring?
Tap immediately if you feel pressure in your lumbar spine. If you have room before the arch is locked in, use your hands to walk your body forward, turn your hips to face the mat to relieve tension, or grab the attacker's ankles from below to break their base.
