有学者提出腰椎间盘突出后引起的免疫反应和炎症改变可能是导致疼痛的一个重要原因[3-4]。

OBJECTIVE: To quantify the stress distribution on the intervertebral disc, interarticular process and iliolumbar ligament of the lumbar vertebrae.

目的：观察轴向载荷下L5~S1上关节突与下关节突之间的峡部、椎间盘和髂腰韧带的应变和表面应力情况。

MAIN OUTCOME MEASURES: Strain at L5-S1, intervertebral disc and iliolumbar ligament was determined using strain gauge.

主要观察指标：L5峡部贴应变片，用应变仪测量L5~S1峡部、椎间盘和髂腰韧带应变。

RESULTS: Under the axial loading on the intact specimen, 70% stress contributed at the pars, 26% at intervertebral disc, and 2.8% at iliolumbar ligament.

结果：正常标本轴向压缩实验，70.7%的应力分布于峡部，分布在椎间盘应力为26.5%，而髂腰韧带则有2.8%应力分布。

On radiologic workup, a prolapse of a lumbar intervertebral disc was ruled out, but agenesis of the infrarenal segment of the inferior vena cava was found, which has caused bilateral deep venous thrombosis.

在放射学的重建上，已排除椎间盘脱出，但却发现下腔静脉的肾下段的缺陷，这种缺陷已经导致两侧的深静脉血栓形成。

Objective To investigate the effect of interbody fusion with or without cage on the loss of intervertebral height.

目的 探讨椎间融合器植入术与单纯椎间植骨术治疗腰椎退行性疾患对椎间隙高度丢失的影响。

BACKGROUND: Lumbar degenerative disease has been commonly treated with nucleus pulposus extirpation or nucleus pulposus extirpation combined with internal fixation; however, with the development of non-rigidity fixation, interspinous dynamic stabilization and intervertebral disk displacement attract more and more attention.

摘要背景：在早期，腰椎间盘退变性疾病的治疗临床常用髓核摘除或髓核摘除加刚性内固定融合技术，但是随着非刚性固定技术的发展，棘突间稳定系统固定和全椎间盘置换在脊柱非融合治疗中逐渐受到人们的重视，其优点日益突出。

According to the first, intravertebral vacuum phenomenon is the result of vertebral osteonecrosis,8,14,17,18 whereas the second theory supports that intravertebral vacuum phenomenon signifies nonunion and pseudarthrosis of a vertebral fracture.20,21 A third theory, which did not find appeal, suggested that intravertebral gas could be of intradiskal origin, leaking to the vertebra through the fracture, since a high coincidence (86%) of intervertebral disk vacuum was noted in cases of intravertebral vacuum.6

第一种理论认为椎体内真空现象是椎体缺血性坏死的结果[8，14，17，18]，而第二个理论认为椎体内真空现象意为着骨不连和假关节[20，21]，另外目前还未广泛接受的第三个理论认为椎体内气体可能是从椎间盘中从椎体骨折裂隙中流入的，椎体内出现真空现象的同时伴有椎间盘内真空的比例很高（86％）[6]。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).
