What does the term 'subluxation' refer to in a medical context?

The term 'subluxation' refers specifically to a partial dislocation of a joint. It occurs when the surfaces of the joint are misaligned but not completely separated, allowing for some degree of movement and stability. This condition can lead to pain, reduced mobility, and potential long-term joint issues if not addressed. Since subluxation implies an incomplete displacement, it highlights the distinction between it and a complete dislocation, where the joint surfaces are entirely separated. Understanding this distinction is crucial in medical contexts, particularly in orthopedics and physical therapy, as it informs diagnosis and treatment options for joint-related issues.
