Chiropractic is conservative care, which means it is non-surgical and drugless. In treating low back "slipped discs", most spine experts agree that conservative care should be tried before surgery is considered, except in severe cases. Chiropractic care has a long history of successfully providing conservative care for disc conditions - and no, chiropractors don't try to "pop a disc back in place".
What is a "slipped" disc?
The disc is a circle of cartilage between each vertebra in the spine that acts as both a shock absorber and a shock distributor. If you jump up and down, imagine what would happen to the stack of bony vertebra that make up the spine without the cushioning of the discs. Move your back side to side. Again, you can visualize the give and take of the discs between the vertebrae. Without discs, the spine simply could not function.
Discs don't really "slip". Instead, they bulge, herniate, or rupture. Saying a disc has "slipped" does suggest that something has "slipped out" and is not where it's supposed to be, which is what happens in disc injuries.
Discs are made up of concentric circles or rings of fibrous material with a tough gelatinous center. When cracks or fissures occur in the fibrous rings, the gelatinous material in the center can begin to push out. A number of different factors may cause the disc to "slip".
