项目摘要

Although computer assisted navigation system are widely used in the treatment of spinal disease in order to minimize the operational damage to the surrounding tissue, the biomechanically spinal joint motion including the degenerative tissue has been insignificantly understood. Instability in the lumbar spinal motion segment (vertebra-disc-vertebra) is noted to be an important factor of spinal disorders. Radiographic or basic biomechanical research for definition of the segmental instability has been well documented. However, some contraversial definitions have been consistently demonstrated.In this project research, to evaluate quantitative spinal mobility and to justify lumber fusion or stabilization, an intraoperative and special designed measurement system has been developed. The system used for measuring spinal segmental mobility is consisted of three segments, spinous process holders, motion generator, and computerized controller. The spinous holders make it possible to handle spinal process without invasiveness for the supra- and inter-spinous ligaments. A continuous displacement that generated from actuator of motion generator at speed of 2.0 mm/s is given to the tip of the spinous processes holders. Measurements of human spinal mobility were made on 24 spinal motion segments in 23 patients with degenerative lumbar disease. (12 men and 11 women) including : 8 segments discopathy, 11 segments spondylitis deformans, 5 segments lumbar spinal canal stenosis. Patient ages ranged from 21 to 83 years (average, 57 years).Each measurement took only about ten minutes on average. Load-displacement curves during spinal segmental motion were recorded with excellent reproducibility. In clinical experiment and conclusion, this system is a accurate tool for measuring intraoperative spinal function. It can be used to evaluate sufficiently the degenerative charasiteristics of spinal segment, and to make pre and post disorder measurements.

虽然计算机辅助导航系统被广泛用于脊柱疾病的治疗，以尽量减少对周围组织的操作损伤，生物力学脊柱关节运动，包括退变组织一直没有显着的了解。腰椎运动节段（脊椎-椎间盘-脊椎）的不稳定是脊柱疾病的重要因素。影像学或基础生物力学研究对节段性不稳定的定义已经有很好的记录。然而，一些相反的定义一直被证明，在这个项目的研究，以评估定量脊柱活动度和腰椎融合或稳定，术中和特殊设计的测量系统已经开发。用于测量脊柱节段活动度的系统由棘突固定器、运动发生器和计算机控制器三部分组成。棘突夹持器可以在不侵入棘上和棘间韧带的情况下处理棘突。由运动发生器的致动器以2.0 mm/s的速度产生的连续位移施加到棘突夹持器的尖端。对23例退行性腰椎疾病患者的24个脊柱运动节段进行了人体脊柱活动度测量。(12男11例，女11例，其中椎间盘病8例，变形性脊柱炎11例，腰椎管狭窄症5例。患者年龄从21岁到83岁不等（平均57岁），每次测量平均只需10分钟。记录了脊柱节段运动期间的载荷-位移曲线，具有良好的重现性。临床实验和结论表明，该系统是一种准确的术中脊柱功能测量工具。它可用于充分评价脊柱节段的退变特征，并可用于病变前后的测量。
