Conducting spinal cord injury model with clip compression in rodents: Pearls and pitfalls

Research on spinal cord injuries is an important and living topic that raises many critical questions that need to be addressed. While numerous articles have compiled and compared various models of spinal cord injuries, there is limited comprehensive guide with clear instructions available for researchers who are unfamiliar with clip compression model. This model creates acute compression damage in spinal cord, which aims to mimic the nature of traumatic spinal cord damage in humans. Purpose of this article is to share our experience on clip compression model, with experience gained from more than 150 animals, and to provide guidance for researchers with lack of experience who wish to design studies with this model. We have defined several key variables, as well as the difficulties that may arise when applying this model. −. Proper preparation, good infrastructure and necessary tools and knowledge of anatomy related is essential to the success of this model. −. Good exposure with non-bleeding surgical site is key factor for surgical step. −. Postoperative care is particularly challenging, and researchers should consider extending their studies over a reasonable time period to ensure that appropriate care could be provided.
