The spinal column reconstruction in the interspinal implants in thing X-stop finite element analysis application Abstract along with people age unceasing growth, between awl in plate the nucleus pulposus gradually will start to degenerate withered, causes between the awl plate thickness to reduce, will then create the yellow ligament and the small surface joint is large, will initiate the so-called lumbar vertebra narrow sickness, will cause the body to have the nerve intermittent slope good symptom.

脊柱重建在棘突间植入物X-stop有限元分析中的应用摘要随着人们年龄的不断增长，锥间盘里的的髓核就会逐渐开始干枯退化，造成锥间盘厚度减小，进而造成黄韧带和小面关节肥大，以至于引发所谓的腰椎狭窄症，造成身体产生神经间歇性坡行症状。

Interspinous process device is a kind of non-fusion implant for posterior spinal surgery. It is classified by static system and dynamic system according to its characteristics.

腰椎棘突间内固定器是脊柱外科后路非融合置入物的一类，根据其特性及作用特点可分为静态系统和动态系统两类。

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。

Although there is fair evidence that articial disc replacement is similarly effective compared to fusion for single level degenerative disc disease and that an interspinous spacer device is superior to nonsurgical therapy for 1- or 2-level spinal stenosis with symptoms relieved with forward exion, insufcient evidence exists to judge longterm benets or harms.

尽管已有相当的证据证明人工椎间盘置换治疗单节段脊柱退变疾病具有和融合手术类似的疗效，也有相当的证据证明棘突间支架治疗1～2个节段伴间歇性跛行的椎管狭窄的疗效优于非手术治疗，但以上都缺乏长期随访的证据。

OBJECTIVE: To explore the performance of xenogenic deproteinized bone scaffold for tissue-engineered bone and the effect on spinal intertransverse fusion in goats.

目的：探讨异种脱蛋白松质骨作为骨组织工程支架的性能，及其在山羊脊柱横突间融合中的作用。

Methods Since 1998,57 cases traumatic thoracolumbar fracture had been oprated by inserted pedicle screw system,posterior decompressive intertransverse process bone fusion,45 patients had been followed up for 16 months(6～22 months)on average.

1998年以来，我院采用椎弓根钉系统内固定，后路减压后外侧植骨治疗胸腰段脊柱骨折57例，其中45例获随访，平均随访16个月（6～22个月）。

METHODS: A total of 200 volunteers who need to receive spinal fusion in the Affiliated Hospital of Qingdao University Medical College were selected, including 102 cases received anterior cervical subcorpectomy combined with iliac bone implantation fusion following decompression, and 98 cases received posterior laminectomy for decompression combined with intertransverse process fusion. Meantime, 223 normal adults were served as the control group.

随机选择青岛大学医学院附属医院住院患者中需行脊柱融合的自愿受试者200例，其中行颈椎前路椎体次全切除减压自体髂骨植骨融合钛板内固定者102例，腰椎后路椎板切除减压横突间植骨融合内固定者98例，以223名健康正常人作对照。

The surgery consisted of one-stage posterior transpedicular eggshell technique, and then expanded the eggshell to the adjacent intervertebra including apex vertebra and both cephal and caudal wedge vertebra combined with their posterior elements, after completion of the VCR, instruments were added to achieve temporary stability.

均采用单纯后路扩大&蛋壳&技术切除侧后凸顶椎（包括顶椎邻近的头尾侧楔变的脊椎），截骨节段上下方各应用2~3对椎弓根螺钉固定，通过器械加压矫形关闭切除后形成的间隙观察手术前后侧后凸的矫正率、术中脊柱短缩、术后站立位身高变化及术后整体平衡情况。。

Myelography with contrast media or CT scan with metrizamide is essential to detect intradural and intramedullary tumors.

持续性两侧小腿疼痛而无背痛病史，也提示为脊柱肿瘤，用造影剂作脊髓X线造影或用甲泛影酰胺作CT扫描探查硬膜内或脊内肿瘤是来可少的。

Intradural spinal tumors are less common than metastases in adults and include neurofibromas, meningiomas, and ependymomas.

多发性骨髓瘤也常累及脊柱，并常导致骨质结构脆弱而产生疼痛，也可以引起病理骨折，成人硬脊肿瘤神经纤维瘤，脑膜瘤和室管膜瘤，较转移肿瘤少见。

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).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
