title: Perspectives in anatomy and pathology of paraplegia in experimental animals.
abstract: Three models of inducing spinal trauma in experimental animals--weight-dropping model, severance-by-knife model, and laceration-type-lesions model--are reviewed critically. Contributions by these models in understanding paraplegia in anatomical and pathological terms are brought out. Important distinctions between subthreshold traumas vs. threshold and suprathreshold traumas, transient and permanent paraplegic syndrome, and regeneration of served axonal fibers vs. prevention of development of permanent paraplegia, are stressed while evaluating each model of spinal trauma. Conceptual contributions by these three models and their bearing on the potential clinical applications are discussed.
