What occurs during a subluxation?

A subluxation occurs when there is a partial loss of contact between the articular surfaces of a joint. This means that while the joint is not fully separated, its alignment is disrupted enough to cause pain and potentially affect its function. This condition can result from trauma, overuse, or underlying joint instability and may lead to symptoms like swelling, decreased range of motion, and joint instability.

In contrast to a complete dislocation, where the joint surfaces are entirely separated and cannot function normally, a subluxation retains some contact between the surfaces. Other choices, like the formation of a callus, are unrelated to the immediate mechanical disruption of the joint itself. Thus, recognizing that subluxation signifies only partial dislocation helps clarify its clinical implications and the necessary approach for treatment and rehabilitation.
