JBJS:硬膜外内固醇注射可增加椎体骨折风险

2013-09-13 佚名 dxy

类固醇激素在临床上被广泛使用,骨科也不例外,医生们常规将类固醇激素经椎板间隙或椎间孔注射入患者硬膜下腔来治疗椎间盘突出或椎管狭窄导致的坐骨神经痛和神经性跛行。给患者带来福音的同时,类固醇激素促进骨细胞凋亡、增强破骨细胞活性、抑制成骨细胞功能、导致患者骨质疏松或骨量降低的发生率却从未被广泛关注。 最近的一项临床回顾性分析发现,绝经后妇女单次硬膜外类固醇注射后髋关节骨密度下降,骨折风险增加。为了验证

类固醇激素在临床上被广泛使用,骨科也不例外,医生们常规将类固醇激素经椎板间隙或椎间孔注射入患者硬膜下腔来治疗椎间盘突出或椎管狭窄导致的坐骨神经痛和神经性跛行。给患者带来福音的同时,类固醇激素促进骨细胞凋亡、增强破骨细胞活性、抑制成骨细胞功能、导致患者骨质疏松或骨量降低的发生率却从未被广泛关注。

最近的一项临床回顾性分析发现,绝经后妇女单次硬膜外类固醇注射后髋关节骨密度下降,骨折风险增加。为了验证硬膜外类固醇注射是否会增加椎体骨折的发病率,美国学者Mandel等进行了一项专题研究,结果发表在近期出版的JBJS杂志上。【原文下载

本研究的目的在于明确腰椎硬膜外类固醇注射对椎体骨折发生的影响。由于激素注射方法各异,从而导致激素对脊柱骨骼影响的程度也不同,因此本研究的对象仅限于经椎板间隙进行硬膜外类固醇注射治疗神经性跛行的腰椎退变性疾病患者。

根据ICD-9疾病分类标准,研究人员筛选出符合腰椎退变性疾病诊断的,且接受过至少一次腰椎硬膜外类固醇注射的患者3415名,随机选择其中3000名患者作为实验组,另选取3000名从未接受过硬膜下激素注射治疗的患者作为对照组。椎体骨折筛选通过放射科数据库进行关键词搜索,关键词包括:骨折、台阶样改变、终板变形,楔形变、椎体高度降低、压缩、成角。

为了减少与硬膜下激素注射无关的椎体骨折的患者入选,研究人员设置了排除标准,年龄<50岁,脊柱肿瘤,PVP或PKP后邻近椎体骨折。每一个纳入研究的患者的影像学资料都被再次人工确认。最后,将配对后的实验组和对照组患者的椎体骨折几率进行统计学比较。

结果显示,实验组和对照组在患者年龄、性别、种族、腰椎病患类型、甲状腺功能亢进或其他类固醇应用上均无显著差异。ICD-9疾病分类中编号722.52、724.2和724.3三种疾病的分布上有显著差异,但差异较小(1.9%,4.2%和4.1%)

《骨关节外科杂志》(JBJS)在线公布的一项新研究结果表明,全膝关节置换术(TKR)后的伴糖尿病患者较非糖尿病患者相比并无更高的感染、深静脉血栓(一种深静脉的血凝块)或者其他并发症风险,相关结果稍后将发表在该杂志2013年3月版上。该研究的作者们试图判定是否血糖水平(血糖控制水平)可以影响TKR患者的预后。52%的糖尿病患者有关节炎病史。先前的研究发现血糖控制不佳可以导致术后并发症的产生。研究者们

JBJS:吸烟是锁骨中段骨折非手术治疗不愈合的高风险因素

锁骨中段骨折如选择非手术治疗不愈合的发生率约为5%-20%,移位性骨折不愈合的风险则更高。有研究显示,早期内固定可获得更好的临床结果,不愈合的比率也相对较低。并且早期内固定也比非手术治疗发生不愈合以后二期内固定的效果更好。基于以上研究,目前对于活动量较大的成人,锁骨中段移位性骨折大多选择早期内固定。然而,这样一来很多本可以通过非手术治疗顺利愈合的患者就要承担手术相关并发症的风险。 至于成

对于严重肱盂关节骨性关节炎的手术治疗而言,采用全肩关节置换还是半肩关节置换,目前尚存有争议,相关病例采用伴肩关节的长期临床效果也缺乏相关研究报道。最近,美国哥伦比亚大学医学院肩肘外科及运动医学研究中心的William N。 Levine, MD等实施了一项临床观察研究,对肩关节骨性关节炎患者采用半肩关节置换的长期临床效果进行了考察,并于近日在J Bone Joint Surg Am上发表了其研究论

自体髂骨移植植骨融合(ICBG)一直是脊柱融合术的金标准,但仍有接近2.8-39%不等的融合失败率。近十年,随着具有骨诱导活性的人工骨蛋白类rhBMP-2的开发,自体髂骨移植进行脊柱间植骨融合的地位受到了挑战。目前已有较多关于rhBMP-2应用效果的文献发表,多个多中心临床研究表明,rhBMP-2和ICBG在临床预后方面具有较多优势:手术时间,术中失血,住院周期,再手术率,恢复工作时间等均有所下降
