What is a subluxation?

A subluxation refers to a partial dislocation where there is an incomplete separation between two articulating bones. This condition often leads to instability in the joint, and while it may not result in a fully displaced joint, it can still significantly affect joint function and may cause pain, swelling, and reduced range of motion.

Understanding this definition is crucial because it distinguishes subluxation from a complete dislocation, which is a full separation of the joint surfaces (as described in one of the incorrect choices). Additionally, since a subluxation involves only a partial displacement, it differs from minor sprains, which are injuries to ligaments, and from joint inflammation, which refers to conditions related to pain and swelling but does not inherently involve dislocation or joint misalignment.
