| 在整个脊柱运动范围中存在着一个中性区域,在这个区域内,脊柱活动时受到的阻力较小。腰椎节段性失稳的定义是在生理载荷下,脊柱的稳定系统将脊柱运动的中性区域维持在生理范围内的能力减退,从而出现脊柱的畸形、神经症状和不能忍受的疼痛。脊柱的稳定系统由被动系统、主动系统和神经控制系统组成。腰椎节段性失稳是腰椎退变过程中一个暂时的阶段。腰椎屈伸侧位片拍摄的是腰椎活动的最后阶段,只反应了脊柱被动系统的功能,而没有反应主动系统和神经控制系统的功能。因为临床表现、腰椎正侧位片和体格检查可以反应脊柱的中性区城和稳定系统,所以能作为诊断腰椎节段性失稳的依据。 |

| Abstract:The neutral zone is the initial portion of the total range of motion of a spinal motion segment during which spinal motion is produced against minimal internal resistance.Lumbar segmental instability is defined as a decrease in the capacity of the stabilizing system of the spine of maintaining the spinal neutral zone within physiological limits,so that there are neurological deficit,majo deformity and incapacitating pain. The stabilizing system of the spine consists of passive,active and neutral control subsystems.Lumbar segmental instability is a temporary phase in the degenerative process of the lumbar spine. Flexion-extension radiographs taken at the end-range of movement will capture only the function of the passive stabilizing subsystem and fail to address the active and neural control subsystems.Diagnosis of lumbar segmental instability may also be based on the patient’s history,plain radiographs and examination findings,as they can address the neutral zone and the stabilizing system. |
