Abstract: Since the first spinal cord injury model was established in 1911, various models, which are similar to clinical situations, have been developed. These were transaction, retraction, compression and vascular exclusion. Nowadays, many new technologies, such as computer-controlled accurate strike, guided precision surgical cut, digital retractor and biomechanical compression device, have been applicated in modeling. With development of science and technology, kinds of models could be closer in simulating different clinical states. This article introduced us the progress and development trends of this spinal cord injury animal model.
