There is a sound basis for the flexion treatment of low backache due to a narrowed lumbar disc, regardless of whether the pain is due to a protruded disc, or subluxation of the lumbosacral or lumbar facets.
Conservative flexion treatment as outlined, and utilizing new apparatus has been found efficient for home treatment.
A new spine-fusion procedure, using a mortised interspinous bone block, has been successful in restoring the intervertebral interspace to normal; in reducing the accompanying subluxation; and in giving internal fixation to the routine spine-fusion grafts.
