A joint instability (or flail joint ) is a reduction in the safe, stable guide of the joint forming bone during a movement with simultaneous abnormal increase in the possible range of movement.

This guidance usually takes place actively through the muscles and passively through the capsular and ligamentous apparatus .

The causes of a malfunction are:

A subluxation is used when there is a significant increase in the possible range of motion . If the joint connection is completely broken, there is a dislocation ( dislocation ). If this happens again and again with physiological movements without additional force, one speaks of a habitual dislocation .
