摘要:

牵张性脊髓损伤是由脊髓上一定程度的牵张或纵向张力引起的,常发生在临床接受严重脊柱畸形矫正的患者中。随着牵张程度和持续时间的增加,脊髓损伤在神经生理学、组织学和行为学方面变得更加严重。但是目前很少有研究聚焦于牵张性脊髓损伤的相关特征。此次综述纳入了22项相关研究,从而对牵张性脊髓损伤动物模型的神经生理学、组织学以及行为学特征进行了系统回顾,认识到牵张性脊髓损伤原发性损伤和继发性损伤的相关机制,同时在原发性损伤中明确了牵张强度和时间的不同给脊髓损伤带来的影响。这一综述为牵张性脊髓损伤模型的建立以及相关基础研究提供新的思路,也为临床的诊断和治疗提供了帮助。

Abstract: Distraction spinal cord injury is caused by some degree of distraction or longitudinal tension on the spinal cord and commonly occurs in patients who undergo corrective operation for severe spinal deformity. With the increased degree and duration of distraction, spinal cord injuries become more serious in terms of their neurophysiology, histology, and behavior. Very few studies have been published on the specific characteristics of distraction spinal cord injury. In this study, we systematically review 22 related studies involving animal models of distraction spinal cord injury, focusing particularly on the neurophysiological, histological, and behavioral characteristics of this disease. In addition, we summarize the mechanisms underlying primary and secondary injuries caused by distraction spinal cord injury and clarify the effects of different degrees and durations of distraction on the primary injuries associated with spinal cord injury. We provide new concepts for the establishment of a model of distraction spinal cord injury and related basic research, and provide reference guidelines for the clinical diagnosis and treatment of this disease.
