CLINICAL BIOMECHANICS OF THE CERVICAL SPINE

颈椎损伤、退变(脊椎病)、神经根受压 (神经根病)和脊髓压迫(脊髓病)是主要的 颈部疼痛、畸形和神经功能障碍的原因 区域。尽管对脊柱的研究本身很重要，但它提供了 关于脊髓和神经根的信息有限。该计划的目的是 目前的建议是全面研究力学基础 颈椎的局部、神经根性和脊髓性症状。 我们暂时没有这方面的资料。 这项综合研究包括三个基本部分。首先，要确定 韧带劳损与椎间关节突关节改变 颈椎的生理运动。第二，衡量 神经根和脊椎的生理运动和应变 电源线。最后，为了量化颈椎的三维解剖 各种生理姿势使用冷冻显微镜切片，X射线和 CT扫描。 这项工作的意义将在几个不同的领域。这个 关于功能关系的一套综合生物力学数据 在颈椎系统的各个组成部分之间，即， 椎骨、韧带、脊髓和神经根将可用于 第一次。它将为理解的功能提供基础 颈椎系统。从而使关联成为可能 准确地说是具有临床症状的解剖紊乱 在一个病人身上。它也将有助于新的和更多的设计 对各种问题的有效诊断和治疗模式 颈椎。

Cervical spine injuries, degenertion (spondylosis), nerve root compression (radiculopathy) and spinal cord compression (myelopathy) are the major causes of pain, deformity and neurological disfunction in the cervical region. Studies of the spinal column alone, while important, provide limited information about the cord and nerve roots. The purpose of the present proposal is to study in a comprehensive manner the mechanical basis of local, radicular and myelopathic symptomatology in the cervical spine. Such information is not available presently. This comprehensive study has three basic parts. Firstly, to determine ligamentous strains and intervertebral foramenal changes due to physiological movements of the cervical spine. Secondly, to measure physiological movements of, and strains in,, the nerve roots and spinal cord. Finally, to quantify 3-dimensional anatomy of the cervical spine in various physiological postures using cryomicrotome sectioning, X-rays and CT-scans. Significance of this work will be in several different areas. The comprehensive set of biomechanical data about the functioning relationships between the various components of the cervical spine system, namely, vertebrae, ligaments, spinal cord and nerve roots will be available for the first time. It will provide the basis for understanding the functioning of the cervical spine system. Thereby making it possible to correlate precisely the anatomic derangements with clinical presentation of symptoms in a patient. It will also be helpful in the design of new and more efficient diagonostic and treatment modalities for the various problems of the cervical spine.
