title: The torsional injury of the lumbar spine.
abstract: Torsional injuries of the lumbar spine occur with load application accompanied by axial rotation. In these, damage occurs in both the annulus of the disc and the neural arch. Traumatic arthritis then develops, as do torsional deformities, and these lead to neural compromise. Myelographic defects arise as a result of torsional obliteration of the dural extensions.
