If you don't rely on manual reduction to correct spinal dislocation, you can't get better by doing yoga or traction. Doing yoga can avoid deviation, but only if you practice before the bone deviates, otherwise you will find that there are many postures that you can't reach, and traction will not depend on, but can only be improved or alleviated. The dislocated spine is still dislocated. You'd better find a masseur or osteopath to adjust it.
