A subluxation is defined as a partial or incomplete dislocation of a joint or organ. It occurs when one of the bones in a joint is partially out of its normal position, differing from a complete dislocation (luxation) where the bones are entirely separated. Subluxations can often return to their normal position without medical intervention, although some cases may require treatment.
Medical Context
In medical terminology, subluxation is recognized across various fields including orthopedics, dentistry, and chiropractic care:
- Joints: A joint subluxation can happen in various joints such as the shoulders, fingers, kneecaps, and hips. For example, a common instance is “nursemaid’s elbow,” where the radial head is subluxated from the annular ligament. Subluxations can be caused by trauma, repetitive motion, or certain medical conditions.
- Ophthalmology: In the eye, a subluxation refers to a condition called ectopia lentis, where the lens is displaced. This can occur due to trauma or systemic disorders like Marfan syndrome.
- Dental: A dental subluxation involves a tooth that has increased mobility but remains in its socket, often treated conservatively with good oral hygiene and possibly a temporary splint.
Chiropractic Perspective
In chiropractic practice, the term “vertebral subluxation” is often used, though it is considered controversial and lacks scientific support. Chiropractors claim that these subluxations can affect overall health, but mainstream medicine disputes these claims due to insufficient evidence.
Overall, while subluxations can be a common occurrence in various contexts, their implications and treatment can vary significantly depending on the specific joint or organ involved.
