FAQ
Frequently Asked Questions
A dislocation (luxation) is a complete separation of the joint surfaces. A subluxation is a partial dislocation where the bones remain in partial contact but are misaligned.
Yes, it is a standard term in orthopedics, rheumatology, and radiology for a partial dislocation. Its use and specific definition in chiropractic care is where controversy sometimes arises within the wider medical field.
Some minor subluxations, especially in hypermobile individuals, may reduce spontaneously. However, many require manual manipulation (adjustment) or specific exercises to correct the alignment and stabilize the joint.
The controversy stems primarily from the chiropractic use of 'vertebral subluxation' as a theoretical, often sub-radiographic, lesion affecting nerve function. This conceptual model is not widely accepted in mainstream medicine, which typically uses the term for objectively demonstrable partial dislocations seen on imaging.
