Spine:单独前路腰椎融合术效果可行

2014-07-29 李宁 丁香园

腰椎退变被认为是腰椎病或退行性椎间盘疾病。如果不处理,可能会导致腰椎狭窄、小关节退变和退行性腰椎滑脱,最终导致腰痛或坐骨神经痛。手术干预措施包括前路腰椎融合术、360°腰椎融合术、后路脊柱融合和椎间盘置换术。 一般来讲,如果存在椎间盘严重变性、脊柱不稳定、神经根压迫或非手术干预失败,融合手术就会被考虑。过去,后路腰椎融合辅以前路腰椎融合能够充分固定和融合,然而其手术发病率、术后疼痛、住院日均

腰椎退变被认为是腰椎病或退行性椎间盘疾病。如果不处理,可能会导致腰椎狭窄、小关节退变和退行性腰椎滑脱,最终导致腰痛或坐骨神经痛。手术干预措施包括前路腰椎融合术、360°腰椎融合术、后路脊柱融合和椎间盘置换术。

一般来讲,如果存在椎间盘严重变性、脊柱不稳定、神经根压迫或非手术干预失败,融合手术就会被考虑。过去,后路腰椎融合辅以前路腰椎融合能够充分固定和融合,然而其手术发病率、术后疼痛、住院日均增加。同时,360°腰椎融合具有花费和感染风险高的缺点。

令人惊讶的是,关于单独前路腰椎融合固定的评估,目前仍缺乏资料。于是,来自美国的Lammli学者等报道了应用单独前路腰椎融合术并人类骨形态蛋白2治疗一系列退变性腰椎疾病(L4-S1),该研究已在近期的Spine杂志上发表。

在该研究中,118例患者(58.5%为女性)获得了随访,平均年龄为43 ± 10岁。91.5%的患者为白种人。不吸烟患者占50%。

研究结果显示患者术后2年残疾障碍功能指数(ODI)和视觉疼痛得分(VAS)明显改善(P<0.01)。术后2年椎间盘高度较术前明显增高(P<0.01),而在毗邻节段椎间盘高度没有明显降低。107名患者(93.0%)获得满意的融合。在手术时间(单节段66分钟,双节段91分钟)、失血量(单节段48±30.9ml,双节段49.5±26.1 ml)和住院日(单节段2.6±0.8天,双节段3±0.6天)方面,单节段或双节段的前路腰椎融合术少于360°腰椎融合和椎间盘置换。



本研究的特点为:1.研究人员回顾了2005年-2010年间采用单独前路腰椎融合入路并人类骨形态蛋白2治疗退变性腰椎疾病的一系列患者(118名)的短期(术后2年)的临床、功能、影像结果。2.研究发现单独前路腰椎融合术的残疾障碍功能指数、视觉疼痛得分、椎体高度明显改善,而且手术时间、失血量、住院日较短。

可见,前路腰椎融合固定术治疗退变性腰椎疾病是可行的,可认为是值得考虑的手术措施。

JSDT:椎间盘突出融合术的长期疗效于椎间盘切除术相似

不融合的单纯部分椎间盘切除术(间盘切除)为治疗椎间盘突出下肢放射痛的标准方法。但由于椎间盘为脊柱运动单元的生物力学稳定装置,学者认为椎间盘切除术后节段不稳为残余腰痛和椎间盘突出复发的危险因素。目前有多种融合技术,包括PLIF,TLIF,这些新技术融合了原发性椎间盘突出节段。 而单侧椎间盘切除术与融合术两者长期随访疗效的研究,相对较少。 日本福岛医科大学医学院骨科的学者进行了一项回顾

JSDT:肥胖患者微创椎间孔腰椎间融合术安全可靠

肥胖被认为是腰痛的独立危险因素。美国国立卫生研究院对肥胖的分级如下规定:BMI在25-30间为超重,30-40则为肥胖。外科医生认为,肥胖患者手术暴露困难,手术时间较非肥胖患者延长。并且,有研究认为,超重或肥胖患者行选择性脊柱融合的围手术期并发症发生率为36.9%。 目前,肥胖和非肥胖患者行微创或开放脊柱手术的研究有大量报道,然而,没有研究比较超重或肥胖患者行微创或开放椎间孔腰椎融合术的疗效

Spine J:颈5/6前路融合后颈椎曲度不良可致邻近节段退变

颈前路融合术后10年内,邻近节段退变可影响超过四分之一的手术病例。邻近节段退变的危险因素包括:术前即有邻近节段退变,做过颈椎融合,颈椎曲度不良。尸体模型的研究表明,颈椎矢状位曲度不良可增加邻近节段椎间盘压力。 C2和C7之间的Cobb角未描述相对于C7,C2的位置。在矢状位上,C2相对于C7的位置,联系紧密。在对52例因腰椎问题就诊的患者及100名志愿者站立位X线片的研究中发现,C2铅垂

Neurosurg Focus:三柱截骨术并发症率与脊柱融合相当

重度脊柱畸形往往被认为是多平面复杂性脊柱畸形,伴有侧凸、后凸及前凸中的一种或多种,其椎体间柔韧性明显下降,脊柱严重不平衡,只有手术才能较好的恢复生理上整体性和局部性的平衡。在脊柱畸形的手术治疗中,脊柱融合术是应用最为广泛的一种。在脊柱融合术应用的半个多世纪里,“融合”早已成为脊柱畸形治疗的“金标准”。 随着现代脊柱外科矫形技术的不断发展,对重度脊柱畸形,尤其是重度僵硬性脊柱畸形,单纯脊柱融合

吕国华:低龄先天性脊柱侧凸的手术时机

2014中国脊柱侧凸年会学术专题一:低龄先天性脊柱侧凸的手术时机 专题主持:吕国华教授 医学界将年龄<10岁或处于青春发育前期的脊柱侧凸称为低龄儿童脊柱侧凸。低龄儿童脊柱侧凸的特点是脊柱及胸腔脏器都处于生长发育的高峰期。先天性脊柱侧凸极少有非手术治疗的适应症,无论是支具治疗还是体操按摩,均不能有效减缓或控制原发侧凸的进展。手术治疗主要围绕提高矫形效果,保留脊柱生长,减

Spine:非固定与固定融合治疗腰椎管狭窄长期疗效相当

腰椎管狭窄的手术治疗方法为椎板切除减压,融合或不融合,也是美国上世纪80年代以来腰椎手术中增长最快的手术适应症。迄今为止,关于脊柱影像或手术方式的选择(椎板切除,椎板切除+内固定+融合,椎板切除+非内固定融合),尚无定论。而且,椎管狭窄的手术率千差万别,不同地域差别高达12倍。不同国别也不同,美国为脊柱手术率最高的国家。 很多研究对椎管狭窄的最佳手术方式进行了探讨。2005年cochrone
