峡部

It is assumed that the main causes of the disease are developmental efect of the lumbar spine isthmus and trauma.

我们认为峡部发育细小和外伤的作用是发生峡部裂的主要原因。

Objective:To provide practical anatomy data about the lumbar isthmus and to quantitatively evaluate structural features of the lumbar isthmus and its relationship to adjacent anatomic structure,and to understand the vulnerability of the pars interarticular of the fifth lumbar vertebra.

目的 ：提供腰椎峡部的应用解剖学资料，定量评价腰椎峡部的结构特点及其与毗邻结构的解剖关系，探讨腰 5椎弓峡部易患病性的解剖基础。

The MPR was used to measure the height and width of posterior arch in the point of vertebra artery overpass, the height of lateral mass benenththe posterior arch and the height and width ofC2 interarticular isthmus.

结果 寰椎椎动脉沟处后弓高度为4.54±1.17mm，椎动脉沟处后弓宽度为8.69±1.12mm，寰椎后弓下侧块高度为4.98±1.07mm，枢椎峡部高度6.95±2.24mm，枢椎峡部宽度6.75±1.39mm，男、女2组之间没有统计学差异。

Methods verificate the feasibility and outcome of surgical treatment isthmic spondylolisthesis with laminoplasty by analysis the surgical data of 16 isthmic spondylolisthesis patients.

通过对16例接受椎板棘突复合体回植方案治疗腰椎峡部裂型腰椎滑脱症患者手术治疗资料的分析，验证椎板棘突复合体回植术在峡部裂型腰椎滑脱手术治疗中的可行性以及临床应用疗效。

objective to study the clinical therapeutic efficacy of posterior vertebral pedicle screw fixation plus intervertebral, isthmic and posterolateral bone grafting for lumbar isthmic spondylolisthesis.

目的：探讨应用后路椎间、峡部及后外侧植骨加椎弓根钉内固定术治疗峡部裂性腰椎滑脱症的疗效。

Results 107 patients were treated with half gland and isthmic portion excision, 43 patients among which were treated with lymph node dissection ;306 patients were treated with half gland and isthmic portion and majority opposite side excision,163 patients among which were treated with lymph node dissection ;and both side of thyroid was removed with half lymph node dissection in 46 patients; 1, 3 and 5 years surviving rate of thyroid carcinoma after operation were 99.0%, 96.5% and 92.6%.

结果 单侧腺叶，峡部切除64例；单侧腺叶，峡部加同侧颈淋巴结清除术43例；单侧腺叶，峡部，对侧腺叶次全切143例；单侧腺叶，峡部，对侧腺叶次全切加同侧颈淋巴结清除术163例；双侧甲状腺全切术加一侧颈淋巴结清扫术46例；局部姑息性切除术28例。

Isthmic lesions involve the pars and can be further broken down into 3 subtypes: stress fractures of the pars, elongated pars defects without fracture, and acute, traumatic pars fractures.

峡性脊椎前移涉及椎体峡部，可进一步分为三个亚类：峡部应力骨折；峡部拉长，没有骨折；急性、创伤性峡部骨折。

Results: Axial scanning including vertebral arch can show spondyloschisis and other signs. These contained widened or stenosis of the spinal canal, stenosis of he lateral recess, the double margin sign, deformity of the lateral recess, the double margin sign, deformity of the intervertebral disc, denegeration of the joint facet and thickening of the ligamentum flavum. Scotty dog sign were showed in images reconstructed along the direction of vertebralarch.

结果：包括椎弓根层而的轴位扫描均能显示峡部裂和其他伴发表现，包括椎管增大或变窄，侧隐窝狭窄、双边征、椎间盘变形、椎小关节退行性变和黄动心忍性韧带肥厚采用平行于峡部的椎弓长轴MPR、MIP斜矢状面重建能直观显示峡部裂的典型表现－猎狗项圈征，正中矢状面重建能显示椎体滑脱。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。

Cell morphology of bacterial ghost of Pasteurella multocida was observed by scanning electron microscopy and inactivation ratio was estimated by CFU analysi.
