The influence of the pathologic state of the hip joint on the total sagittal alignment of the spine was investigated in patients with congenital hip dislocation retrospectively ⋯ The total sagittal alignment of the spine in patients with bilateral hip dislocation was compensated for by anterior angulation of the pelvis and by lumbar hyperlordosis. The main clinical symptoms were lower back pain, and not lower leg pain.

: A new model of experimental spinal cord injury is detailed based on the application of tensile (distraction) force to the vertebral column of the rat. ⋯ : Distraction-induced spinal cord injury was uniformly mild in rats with intact facet capsular ligaments, regardless of distraction parameters. Cutting the facet joint ligaments consistently generated outcome measures associated with mild, moderate, and severe spinal cord injury at 3-, 5-, and 7-mm distraction lengths, respectively.
