The wristlock loads the wrist past its range in one of four directions — hyperextension, rotation, flexion, or lateral deviation toward the radius or ulna, with hyperextension and rotation the two you will actually meet. For the attack, see Wristlock. This page covers defending it, which is almost entirely a matter of what the hand is doing before anyone grips it.
The wristlock is unusual among submissions in that the defender supplies the opportunity with a posture rather than a mistake of position. An open hand posted flat on the mat, a palm pushing on a hip, a hand splayed against a shoulder to frame — each of those is a wrist already at the edge of its range, waiting for someone to close the last few degrees. The attacker does not have to isolate a limb or pass a guard. They have to notice a hand.
That makes the defence unusually cheap and unusually easy to neglect. It is a habit about hands, held permanently, rather than a technique deployed when a wristlock starts.
Elevated RiskWristlock (Defence) is an elevated risk technique. The wristlock loads the radiocarpal and intercarpal joints past range. The wrist is a small joint with a short travel between comfortable and damaged, and its pain signal arrives later relative to structural damage than the elbow's or the knee's — a defender can feel a wristlock as merely unpleasant while ligament and capsule are already loaded. There is also very little visible movement to warn a training partner that the joint is at its limit. Serious injury can occur Very short. The travel from set to damage is a few degrees, and the pain warning is less reliable than on larger joints..
If you are new to this technique: read this section before anything else. Understanding the danger is part of understanding the technique.
The person applying the technique is responsible for releasing immediately.
