Experimental spinal cord transection injuries followed by spinal cord destruction and gentle resection of the destructed cord tissue necessarily lead to a gap between both of the cord stumps. For any attempts to reconstruct the cord or to bridge this gap by transplantation it may be useful to narrow or close the gap. This can be done by vertebral resection. The technique of upper lumbar vertebra resection in cats and rabbits with and without spinal cord lesion is presented. The spine is shortened by approximately 20 mm by spondylectomy. This length exceeds the 10-14 mm long gap in the spinal cord which is created by a spinal cord crush injury using haemostatic forceps and the subsequent destruction zone resection which is performed seven days later. The upper lumbar vertebra is resected by the posterior approach and the spinal cord is sufficiently exposed to perform spinal cord reconstruction experiments.
实验性脊髓横断损伤后，继以脊髓破坏并轻柔切除被破坏的脊髓组织，必然会导致两个脊髓残端之间出现间隙。对于任何通过移植来重建脊髓或桥接此间隙的尝试而言，缩小或闭合该间隙可能会有所帮助。这可以通过椎体切除来实现。本文介绍了在有或无脊髓损伤的猫和兔中进行上腰椎椎体切除的技术。通过椎体切除术可使脊柱缩短约20毫米。这一长度超过了使用止血钳造成脊髓挤压伤并在七天后进行后续破坏区切除所形成的10 - 14毫米长的脊髓间隙。通过后路切除上腰椎椎体，可充分暴露脊髓以进行脊髓重建实验。
