Lumbar Spine, Trauma

aka
*spondylolysis deformity,
*spondylolisthesis

Fracture of the lumbar spine can occur whenever forces applied to the lower spinal column exceed the strength and stability of the spinal column unit.
Common injuries resulting in fractures of the lumbar spine include
fall from a height; motor vehicle
pedestrian accidents;
penetrating trauma, including gunshot wounds and stabbings.

Unstable injuries to the pelvis often are associated with injury to the sacral plexus and the lower lumbar spine.

A lumbar spine burst fracture results from hyperflexion, which produces wedge compression of one or more vertebral bodies.
Because of the rigidity of the ribcage, most of these fractures occur at the L1 or L2 level.
The lumbar spinal canal is relatively wide in relation to the lower spinal cord and the conus; thus, lower thoracic spinal cord injuries are commonly incomplete.

Oblique views of the lumbar spine are useful in the evaluation of spondylolysis of the pars interarticularis.
The so-called Scottie dog configuration may demonstrate a defect in the "neck" of the dog-shaped configuration in patients with spondylolysis.
