J Neurosurg Spine:胸椎后纵韧带骨化在后路减压融合术后仍旧进展并增大

2014-11-30 王海强 丁香园

后纵韧带骨化为脊柱韧带的异位骨化,压迫脊髓而可引起脊髓病变。尽管文献中关于颈椎后纵韧带骨化的进展报道很多,关于胸椎后纵韧带骨化进展的情况,尚不明确。目前,对于胸椎后纵韧带骨化引起压迫症状的首选治疗为后路减压和固定融合,短期疗效好。前路减压技术要求高,并发症也高。 一般认为,脊柱内固定可减少脊髓压迫,进而通过消除动力效应和减少机械应力而抑制骨化。尽管后纵韧带骨化长期进展可抵消手术效果,但胸椎后纵韧

后纵韧带骨化为脊柱韧带的异位骨化,压迫脊髓而可引起脊髓病变。尽管文献中关于颈椎后纵韧带骨化的进展报道很多,关于胸椎后纵韧带骨化进展的情况,尚不明确。目前,对于胸椎后纵韧带骨化引起压迫症状的首选治疗为后路减压和固定融合,短期疗效好。前路减压技术要求高,并发症也高。

一般认为,脊柱内固定可减少脊髓压迫,进而通过消除动力效应和减少机械应力而抑制骨化。尽管后纵韧带骨化长期进展可抵消手术效果,但胸椎后纵韧带骨化在脊柱固定后是否进展,尚不明确。

日本东京大学医学院骨科的学者进行了一项随访研究,提示胸椎后纵韧带骨化在后路减压融合术后仍旧进展并增大,文章于2014年11月发表在J Neurosurg Spine上。

该研究纳入9例胸椎后纵韧带骨化行后路减压、内固定融合的连续病例,随访时间至少3年。对手术前和最后随访时胸椎的薄层CT进行分析,在CT矢状面重建图像中确定胸椎压迫最明显的节段,并在以上确定的平面的轴位图像上,采用医学数字图像和交流DICOM软件,测量骨化区域面积(图1)。

        图1 A:在CT矢状位重建图像上选定突出最明显平面(横线);B:选定平面的横截面;C:使用软件功能(绿色框)计算骨化区域面积。

术前、术后出院时及最终随访时脊髓病变的严重程度采用JOA评分确定下肢肌力功能。

结果显示,所有患者,后纵韧带骨化面积增加,从手术前的83.6±25.3mm2增加到最终随访时的114.8±32.4 mm2+。神经功能并未因后纵韧带骨化进展而加重。

以上结果提示,胸椎后纵韧带骨化的面积,在后路固定后,依然增大。尽管脊柱局部活动度降低,后纵韧带骨化并未缩小或停止进展。对于胸椎后纵韧带骨化的患者,医生应当注意到其进展的情况。

本研究首次报道了胸椎后纵韧带骨化在脊柱固定后的进展,其潜在的机制尚不明确,有待进一步研究。

JNS:最上端融合椎的节段决定交界性后凸的类型

临床对于各类复杂脊柱畸形实施矫形手术时,常需行跨腰骶椎长节段固定融合。脊柱长节段固定融合对于脊柱畸形具有良好的三维矫形效果,但由于脊柱腰骶部及骶髂关节局部独特的解剖结构和复杂的生物力学特征,使得腰-骶-骨盆区域的手术内固定治疗成为脊柱外科的难题。 脊柱长节段固定至骶椎的临床患者,远端固定融合区域常由于骶骨螺钉松动或拔出而导致内固定失败。由于融合节段的正确选择是手术成功的关键,选择不当会引起术后效

JBJS:青少年脊柱侧弯异常椎弓根多见于胸椎凹侧,顶椎附近

与其它脊柱内固定器械相比,椎弓根螺钉具有更好的抗拔出力和矫形能力。使用椎弓根螺钉可提高侧弯的三维矫形,融合节段短,翻修次数也少。椎弓根螺钉置钉需要深入理解椎弓根的形态。置钉不当可损害把持力,或导致严重的并发症,包括邻近脏器、血管和神经结构的损伤。 有学者通过三维重建、CT和MRI观察了青少年特发性脊柱侧弯椎弓根的形态,发现凹侧椎弓根较窄,与年龄、Risser征、侧弯角度与旋转无明显相关性。椎

Spine J:脊柱侧弯术后胸椎平背是腰椎间盘退变危险因素

青少年脊柱侧弯的长期随访研究引起了研究者对手术技术,矫正率和退变的关注。由于融合节段远端邻近节段负荷过重,而引起早发的椎间盘退变。常见于不能恢复脊柱矢状平衡的后路内固定系统。 最近的一项脊柱侧弯手术后10年以上的长期随访研究表明,椎间盘退变最易发生于融合节段很远的腰5第1间隙,不能归结于侧弯类型或腰椎及骨盆的矢状面参数。矢状面不平衡与椎间盘退变和临床疗效负相关。 为确定脊柱侧弯术后

AAOS 2014:大尺寸椎弓根螺钉对胸椎椎管直径无影响

从生物力学角度讲,直径较大的椎弓根螺钉能提供更有力的固定强度,但椎弓根的膨胀或内壁破损有使椎管直径变小的潜在可能,若这种可能性真的存在,将可能引起脊髓或神经受压。本研究证实,至少对于胸椎来说,螺钉直径的增加并不会使椎管变窄,发生骨壁破损的研究对象中133例为外侧壁破损,仅1例为内侧壁破损,且未累及椎管。 已有研究证实,应用超过椎弓根直径的螺钉可以使椎弓根扩张并增加固定

Spine J:多节段胸椎黄韧带骨化症应尽早减压治疗

胸椎黄韧带骨化(Ossification of the ligamentum flavum, OLF)是发生在黄韧带的一种异位骨化。当骨化的韧带增厚、增大到一定程度时,压迫胸段脊髓,引起神经功能障碍,即为胸椎管狭窄症。OLF是胸椎管狭窄症的常见原因之一,可以发生在胸椎的任一节段,也可连续2节段以上受累或呈跳跃性分布,其中上胸椎与下胸椎最为多见。 【原文阅读】 越来越多的研究证据表明,黄韧带骨化是
