A vertebral subluxation involves which type of spinal articulation?

The concept of a vertebral subluxation primarily pertains to intervertebral articulations, as it specifically involves the relationship between adjacent vertebrae and their aligned position. While a subluxation certainly impacts how weight is distributed through the spine as a whole, it specifically addresses the misalignment or altered biomechanics between the individual vertebral bodies and the intervertebral discs.

A subluxation represents a partial dislocation or misplacement of these components, which can lead to altered motion and functionality, ultimately affecting how weight is transmitted and absorbed during various activities. Therefore, weight-bearing is indeed a relevant context, as the spinal column must support the body's weight, but it is the intervertebral articulation that is fundamentally involved in the definition and concept of subluxation.

The terminology around subluxation emphasizes the interaction between the vertebrae and the associated intervertebral structures, thus supporting the articulation classification of intervertebral in the context of this question.
