Difference between Instability and Fluctuation

INSTABILITY vs FLUCTUATION: NOUN

The quality or attribute of being unstable and irresolute
An unstable order
A state of disequilibrium (as may occur in cases of inner ear disease)
The quality or condition of being unstable.
The state of being unstable; want of stability or firmness, physical or moral; liability to fall, fail, give way, or suffer change.
Lack of determination of fixedness; inconstancy; fickleness; mutability; changeableness
The quality of being unstable.
A state that is not in equilibrium, or in which a small change has a large irreversible effect.
A lack of balance or state of disequilibrium
Unreliability attributable to being unstable

The quality of being unsteady and subject to fluctuations
A wave motion
An instance of change; the rate or magnitude of change
A motion like that of waves; a waving; movement in different directions: as, the fluctuations of the sea.
Alternating action or movement; a wavering or varying course; mutation: as, the fluctuations of prices or of the funds; fluctuations of opinion.
In medicine, the alternating motion of pus or other fluids perceptible on palpation.
Synonyms and Oscillation, vacillation.
Produce; fruit.
A motion like that of waves; a moving in this and that direction.
A wavering; unsteadiness
The motion or undulation of a fluid collected in a natural or artifical cavity, which is felt when it is subjected to pressure or percussion.

This presents a paradox, patients with cervical instability are getting surgeries that cause more instability and deformity.
Anterior instability is the most common form of glenohumeral instability and may be associated with nerve injury.
This further indicates that instability in area became major responsible factor for production instability.
