Обзор

Radial deviation wrist locks bend the wrist laterally toward the thumb side (radial side), stressing the ulnar collateral ligament and the ulnar-side wrist structures. [1] These are less common than flexion or extension wrist locks but can be applied effectively from grip fighting situations and guard positions. [2],[3]

Биомеханический механизм

Primary Action — Forced flexion, extension, or rotation of the wrist beyond its normal range of motion
Joints Involved — Radiocarpal joint (wrist), intercarpal joints, distal radioulnar joint
Force Vector — Two-point control — one hand stabilises the forearm while the other drives the wrist into flexion, extension, or deviation
Vulnerability — Small joint with limited muscular protection makes it susceptible to sudden, low-force submissions

Позиция и вход

From any grip exchange — During grip fighting, isolate the opponent's wrist with two-on-one control and apply sudden flexion or rotation
From guard (gi) — When opponent posts a hand on the mat or chest, trap the wrist and apply downward pressure for the wrist lock
From mount or side control — Opponent posts to escape, trap the wrist against the mat and apply the lock

Заметки по тренировке

✓Radial deviation wrist lock bends the hand toward the thumb side — attacking the wrist from the lateral direction by forcing the thumb toward the inner forearm (Danaher, New Wave Jiu Jitsu, 2020)
✓This lock is less intuitive than flexion or extension but extremely painful: the wrist has very limited range of motion in radial deviation, making the lock effective with minimal movement
✓Radial deviation appears in aikido's yonkyo technique: pressure on the radial nerve combined with lateral wrist bending creates both pain compliance and structural threat
✓The lock is applied by gripping the opponent's hand and bending it thumb-side-first toward the forearm — the limited range means the submission happens quickly
✓Radial deviation locks are often accidental: during scrambles, grip fighting, and wrist control, the hand is sometimes bent in this direction unintentionally
✓The radial deviation lock combines effectively with extension: bending the hand backward and toward the thumb side creates a compound lock that attacks multiple structures
✓In self-defence, radial deviation is used to control and redirect: twisting the wrist laterally while stepping off-line controls the attacker's balance through their wrist

Типичные ошибки

!Not controlling the forearm — without forearm control, the opponent simply moves the entire arm to relieve the lateral bend
!Confusing radial and ulnar deviation — radial deviation bends toward the thumb; ulnar deviation bends toward the pinky; each attacks different structures
!Applying excessive force — the wrist has very little range in radial deviation; the lock can damage structures with surprisingly little force
!Not recognising the opportunity — radial deviation locks appear during specific grip configurations; learn to identify these moments
!Attempting with a single-hand grip — use both hands to control the hand and forearm for sufficient force and control
!Not combining with other wrist attacks — radial deviation defence often opens extension or flexion; flow between directions
!Training only radial deviation in isolation — it is most effective as part of a complete wrist lock system

From Clinch

Род

The radial deviation wrist lock from the clinch applies sideways pressure to the wrist — bending it toward the thumb side (radial deviation) — while standing in a clinch position. [1,2] The attacker isolates the opponent's wrist during a clinch exchange, then applies lateral force to deviate the wrist beyond its natural radial range of motion. [1] The clinch provides body-to-body contact that prevents the opponent from simply pulling away, making the wrist lock more controllable than from distance. [1] This is a quick, opportunistic attack during standing grappling exchanges. [1,2]

From Closed Guard

Род

The radial deviation wrist lock from closed guard applies sideways wrist pressure toward the thumb side while the attacker maintains closed guard control. [1,2] The attacker isolates the opponent's posting hand from inside closed guard, controls the wrist, and applies radial deviation — pushing the hand toward the thumb — while the guard prevents the opponent from posturing away. [1] This is an opportunistic attack when the opponent posts a hand inside the guard for balance, exposing the wrist to manipulation. [1] Closed guard provides the control needed to finish. [1,2]
