Abstract

The human spine is a complex biomechanical system composed of multiple articular structures controlled by muscles. Spine diseases are frequently related to a loss of stability. Dedicated imaging protocols have been developed to evaluate spinal instability. Dynamic radiography with lumbar flexion-extension is used most often; however, in traumatic instability, computerized tomography provides better diagnostic accuracy for fracture detection. Novel technology improvements allow acquisition of dynamic MRI with axial load or upright standing techniques to simulate a more pathologic condition compared with conventional supine scans. This article reviews the basic concepts of spinal instability and describes the role of different imaging techniques in its assessment.

摘要

人类脊柱是一个复杂的生物力学系统，由多个受肌肉控制的关节结构组成。脊柱疾病常与稳定性丧失有关。已经开发了专门的成像方案来评估脊柱不稳定。最常使用腰椎屈伸动态放射摄影；然而，在创伤性不稳定中，计算机断层扫描在骨折检测方面具有更高的诊断准确性。与传统的仰卧位扫描相比，新技术的改进允许通过轴向负荷或直立站立技术获取动态磁共振成像，以模拟更接近病理状态的情况。本文回顾了脊柱不稳定的基本概念，并描述了不同成像技术在其评估中的作用。
