本文介绍了一种测量离体人颈椎椎间盘压力的新技术。使用了微型压力传感器，并设计了插入技术，以最大限度地减少由于插入造成的伪影。该技术被用来测量在纯轴向压缩加载颈椎椎间盘内的压力。所产生的压力随所施加的压缩力线性变化，对于四个样本中的每一个，确定系数（r（2））大于0.99。在800 N压缩下记录的峰值压力在2.4和3.5 MPa之间。(C)2001爱思唯尔科技有限公司版权所有。
A novel technique to measure in vitro disc pressures in human cervical spine specimens was developed. A miniature pressure transducer was used and an insertion technique was designed to minimise artefacts due to insertion. The technique was used to measure the intradiscal pressure in cervical spines loaded in pure axial compression. The resulting pressure varied linearly with the applied compressive force with coefficients of determination (r(2)) greater than 0.99 for each of the four specimens. Peak pressures between 2.4 and 3.5 MPa were recorded under 800 N of compression. (C) 2001 Elsevier Science Ltd. All rights reserved.
