后路

The rigidity, stress, and strain of lumbar spine following PLIF were greater than ALIF, but torsion indexes were smaller than ALIF.

后路椎间融合术的刚度明显强于前路椎间融合术，应变和应力也较前路椎间融合术有优势，但是其扭转稳定性却不如前路椎间融合术。

METHODS: Models of ALIF, PLIF and TLIF were simulated. After examination as normal group, the samples were randomly divided into three groups (n=5). Besides anterior, posterior and transforaminal lumbar interbody fusion include anterior, bilateral pedicle screw fixation was performed.

模拟临床手术建立前路椎间融合术、后路椎间融合术、椎间孔入路椎间融合术3种椎间融合术模型，先将所有标本作为正常对照组进行测试，然后将标本随机分为3组，每组5个标本，制成单纯椎间融合组，分别采用3种椎间融合术测试后，在此基础上再附加双侧椎弓根螺钉内固定进行测试。

Because of the complications of abdominal organs injury or retrograde ejaculation after ALIF, and the high risk of nerve injury after PLIF, these two surgeries were reduce to perform in clinic nowadays. While TLIF has be consider to have less risk of injuries of nerve root, cauda equine, dura matar, and less incidence of lumbar unsteadiness and spondylolithesis.

研究背景腰椎椎体间融合术是目前治疗椎间盘源性下腰痛、腰椎滑脱症、腰椎不稳症等原因引起的下腰痛效果较为满意的一种腰椎融合手术方式，其主要分为前路椎体间融合术、后路椎体间融合术以及经关节突入路椎体间融合术。

For ALIF, this ranged from 0.8 (complete, 100% fusion) to 3.3 (solid fusion of the posterior 25% disc space). For PLIF, the numbers were more aried, ranging from 0.7 (complete, 100% fusion) to 6.9 (solid fusion of posterior 25% disc space with bilateral facetectomy). For intertranserse process fusion, the least motion was with a solid bilateral fusion, with medial healing to the pars (2.0); the greatest motion was found with a solid unilateral fusion without medial healing (6.0). Interspinous process fusion allowed only 1.9 of motion.

前路椎间融合，范围是0.8度（完全、100%融合）到3.3度（后方椎间隙25%的稳定融合）；后路椎间融合范围较大，是0.7度（完全、100%融合）到6.9度（伴有双侧峡部近内侧融合的后方椎间隙25%的稳定融合）；横突间植骨融合，最小值2.0度是双侧偏内侧稳定融合，最大值6.0度是单侧且不偏向内侧融合；椎板棘突间植骨融合只出现1.9度的活动度。

Objective: To measure linear and angular parameters of the posterior structure of the lower cervical spine.

目的：测量国人下颈椎后结构的相关径线及角度，为颈椎后路内固定手术的设计及施行提供参考数据。

From January 2005 to August 2006, 83 cases of CSM who underwent surgery in Tianjin Hospital were enrolled. Among which, there were 48 male and 35 female. The average age was 52 years old (ranging from 35 to 65). 65 cases operated anteriorly and 18 cases posteriorly.

选择2005年1月至2006年8月在我院脊柱外科手术治疗的脊髓型颈椎病患者83例，男48例、女35例；年龄35~65岁，平均52岁；前路减压手术65例，后路减压手术18例。

A combination of Gallie or Brooks techniques and 2 posterior transarticular screws has been shown to be effective for atlantoaxial arthrodesis.

背景概要：Gallie 或Brooks技术和两后路关节螺钉结合已被证明是有效的寰枢椎固定方案。

Methods. A 60-year-old man with athetoid cerebral palsy and a history of posterior occipitocerical fusion presented with quadriparesis. Salage surgery for cerical myelopathy and pseudarthrosis was performed with laminectomy and rearthrodesis using the pedicle screw system. An intraspinal cyst was identified as the main cause of the paraparesis.

一位60岁的手足徐动症样大脑麻痹患者，既往曾行后路枕颈融合术，临床表现为四肢轻瘫，影像学检查示脊髓型颈椎病和假关节形成，采用椎板切除和椎弓根钉系统关节成形术后，发现椎管内存在的囊肿是导致四肢轻瘫的主要原因。

Objective: To investigate the role of bone morphogenetic protein in the autograft and allograft spinal fusion.

观察自体骨用于脊柱后路融合过程中骨形态发生蛋白2-7（BMP-2、BMP-7）的表达，并探讨其在脊柱融合过程中的作用机制。
