wristlock

A wristlock is a joint-lock technique used in martial arts and self-defense to immobilize or control an opponent by applying leverage to the wrist joint. The technique typically involves securing the opponent’s hand or wrist with one or both of the attacker’s hands and then turning or extending the wrist to create torque across the radiocarpal joint and the surrounding ligaments. The resulting pressure can force submission, yield, or disrupt the opponent’s grip to create an opportunity to disengage.

Wristlocks are common in many martial arts and combat systems, including jujitsu, judo, aikido, wrestling, Krav Maga, and Systema. They are used to counter a grab, gain control in close quarters, or finish a confrontation. Variants include straight wrist locks (wrist extension), rotational or spiral wrist locks, and one-handed or two-handed controls, depending on grip and position.

Because the wrist contains several small bones and numerous ligaments, improper application can cause ligament strains, sprains, or more serious injuries such as dislocations. Training under qualified instructors and using proper control and communication is essential. In self-defense contexts, the legality and proportionality of using a wristlock depend on jurisdiction and circumstances.

Historically, joint locks appear across many martial arts; wristlocks are a basic tool in many grappling arts and are often contrasted with longer arm locks or chokes. See also: joint lock, submission wrestling, self-defense.
