项目摘要
The proposed study focuses on understanding and developing new methods to diagnose low back pain
problems resulting from both segmental instability and degenerative changes in intervertebral discs and/or
facets. In the ongoing study, we found that a relationship exists between the severity of intervertebral disc
degeneration and increases in torsional and flexion-extension movements. Significant differences were
found in facet degeneration and disc degeneration between the asymptomatic and the symptomatic
subjects. However, the mechanistic relationship between disc degeneration and the facet joint remains to
be clarified. In Project 1 of the renewal Program Project Grant, we will define kinematic hypermobility in
torsion and flexion-extension in vivo and correlate those measurements with low back pain symptoms. We
will identify factors of prognostic importance to the progression of disc and facet joint degeneration and
symptoms. We propose a five-year study of the in vivo relationship of degenerative changes with segmental
instability of the lumbar spine. In this proposed study, we will re-evaluate, over a five-year interval, 25
asymptomatic normal subjects and 25 age- and sex-matched symptomatic subjects, who were investigated
in the current grant cycle. Hypotheses that we will test in this study are (1) that greater segmental mobility
and/or specific kinematic patterns contribute to accelerated intervertebral disc and facet degeneration over
time, and (2) that load transmission through the facet joints depends on the loading direction and
intervertebral disc degeneration and height, and motion segment level and facet orientation. The specific
aims are (1) to measure changes in rotational and flexion/extension segmental movement associated with
disc and facet degeneration over five years within each subject (a longitudinal in vivo study comparing
normal subjects and mechanical low back pain subjects), and (2) to investigate, using cadaveric lumbar
spines, relationships among disc degeneration and height, segmental movement, disc pressure and facet
joint pressure, and to analyze correlations between altered kinematics and load transmission (an
experimental in vitro study). The outcome from the proposed study is expected to be equally effective for
diagnosis of cervical spinal instability and evaluating many of new motion preservation treatment alternatives
in use or under development.
拟议的研究重点是理解和开发新方法来诊断腰痛
椎间盘的分段不稳定性和退化性变化引起的问题和/或
方面。在正在进行的研究中,我们发现椎间盘的严重程度之间存在关系
变性和扭转和屈伸运动运动的增加。显着差异
在无症状和有症状之间的方面变性和椎间盘变性中发现
