The Oswestry Disability Index score was determined before treatment and at the last follow-up visit.方法：我们进行了临床和影像学资料的回顾性研究，这些资料是在我们单位从2005年6
6、月至2011年6月之间前瞻性收集的550例脊柱结核患者，其中27例患者诊断为非连续性脊柱结核并行相应治疗。除4例患者行保守治疗外，其余均接受后路经椎间孔病灶清除椎间融合内固定术，一期或二期行后路内固定联合前路病灶清除融合术。治疗前后通过血液学及影像学检查、植骨融合及神经功能状态等进行临床疗效的评价。ODI指数评分在治疗前和最后一次随访时确定。,Results: 23 patients (15 M/8F), averaged 44.614.2 years old (range, 19 to 70 yd), who received surgical treatment, were followe
7、d up after surgery for a mean of 52.519.5 months (range, 24 to 72 months). The kyphotic angle was changed significantly between pre- and postoperation (P0.05). The mean amount of correction was 12.67.2 degrees, with a small loss of correction at last follow-up. All patients achieved solid bone fusio

There was a significant difference of Oswestry Disability Index scores between preoperation and the final follow-up.23例患者(15 M/8F)，平均年龄为44.614.2岁（范围19至70岁），都接受了手术治疗，术后平均
9、随访时间为52.519.5个月（24至72个月）。手术前、后的后凸角有明显变化（P0.05），平均矫正率为12.67.2，而最后一次随访时有轻微的矫正丢失。所有患者均获得了坚实的骨融合，既没有死亡率，也没有大的并发症发生。 ODI指数评分在术前和末次随访时比较差异有统计学意义。,Conclusion: The outcomes of follow-up showed that posterior and posterior-anterior surgical treatment methods were both viable surgical options for NSTB. Poster
10、ior transforaminal debridement, interbody fusion and posterior instrumentation, as a less invasive technique, was feasible and effective to treat specific tubercular foci.结论随访结果表明，后路和后前联合入路手术治疗方法都是非连续性脊柱结核可行的手术方案。后路经椎间孔病灶清除、椎间融合和后路内固定术，作为一种微创技术，是治疗特异性结核灶可行和有效的方法。,IntroductionTuberculosis has made a
11、dramatic comeback, in part because of the appearance of anti-tuberculosis drug resistance and the acquired immune deficiency syndrome (AIDS) pandemic. As a destructive pattern of tuberculosis, spinal tuberculosis (STB) accounts for 50% of all cases of musculoskeletal tuberculosis . It is characteriz
12、ed by formation of cold abscess, destruction of the intervertebral disc and the adjacent vertebral bodies, collapse of the spinal elements, and anterior wedging leading to kyphosis. Multilevel noncontiguous spinal tuberculosis (NSTB) is an atypical form of STB, which leaves not less than two adjacen
13、t vertebrae intact between the two foci. The incidence of NSTB is reported as 1.1% to 16.3% .简介由于抗结核药物耐药性的出现和获得性免疫缺陷综合症（艾滋病）的流行导致结核病大量复燃。作为结核病的破坏性形式，脊柱结核（STB）占所有肌肉骨骼结核病的50。它的特点是冷脓肿形成，椎间盘和相邻椎体的破坏，脊柱附件和前柱的塌陷，从而导致脊柱后凸畸形。多节段非连续性脊柱结核（NSTB）是脊柱结核的非典型式，在两个病灶之间留下不少于两个完整的椎体。研究报道NSTB的发病率为1.1% 至 16.3% 。,Recentl
14、y, with whole spine magnetic resonance image (MRI) being applied to aid detection of NSTB, its incidence is higher than previously quoted 4. The treatment regimes regarding NSTB vary from purely medicine to a combination of chemotherapy and surgery. The pendulum of therapeutic strategies to NSTB has
15、 periodically vacillated between non-operative management and radical surgery. In the present study, we seek to discuss the role of surgical treatment method.近年来，随着全脊柱磁共振成像（MRI）的应用帮助检测非连续性脊柱结核（NSTB） ，其发病率高于先前的报道。关于NSTB的治疗方案，从单纯的药物治疗到药物化疗与手术相结合等不同。NSTB治疗方案的摇摆不定在非手术治疗和根治性手术治疗治疗之间定期波动。在本研究中，我们试图探讨手术治疗方

17、tients who were diagnosed and treated as NSTB in our institution from June 2005 to June 2011. Plain radiology, computed tomography and MRI of the spine were performed on all patients admitted with suspected spinal tuberculosis. 资料与方法患者/研究对象：这项研究获得了中南大学湘雅医院伦理委员会的批准。我们进行了临床和影像学资料的回顾性研究，这些资料是在我们单位从2005
18、年6月至2011年6月之间前瞻性收集的550例脊柱结核患者，其中27例患者诊断为非连续性脊柱结核并行相应治疗。可疑脊柱结核而收住院的所有患者均完善普通X线片、CT和MRI等检查。,Whole spine MRI was performed on patients presenting with multi-level symptomatic vertebral infection. A diagnosis of NSTB was defined as vertebral disease additional to the main lesion identified on MRI separa
19、ted by at least 2 normal spinal segment (vertebral body/neural arch and/or intervertebral disc). Written informed consent was acquired from each of the patients to authorize treatment, imageology findings, and photographic documentation.多节段有症状的椎体感染患者进行全脊柱MRI检查，NSTB的诊断被定义为MRI检出附有椎体病变的主要病灶由至少2个正常脊椎节段（
20、椎体/神经弓和/或椎间盘）所分开。每个患者均签署书面知情同意书以知情治疗、影像学结果及照相记录等。,The cohort comprised 17 males and 10 females, averaged 44.713.2 years old (range, 1970), with a minimum 2-year follow up. Apart from 4 cases treated conservatively, the remainder 23 patients (15 M/8F), averaged 44.614.2 years old, received surgical t
21、reatment . The location of infection varied from cervical spine down to lumbar spine . The clinical outcomes were measured preoperatively, immediately after surgery and at ultimate follow-up visit in term of hematologic and radiographic examinations and neurologic status.研究对象包括17例男性和10例女性患者，平均年龄为44.
22、713.2岁（19-70岁），至少随访2年。除4例患者行保守治疗， 其余23例患者(15 M/8F)，平均年龄为44.614.2岁（19至70岁），都接受了手术治疗，感染的部位从颈椎到腰椎不同。术前、术后即可及末次随访均通过血液和影像学检查并神经功能状态等方面来进行临床效果的测量。,Hematologic examination included erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), liver function test and blood count. The neurologic status wa

Kyphotic angel was measured by drawing two linesone was along the top surface of the immediate upper normal vertebral body, and the other was away from the diseased segment. The bone fusion was assessed by the Moon standard. Bone fusion was characterized
24、 by reappearance of bone trabeculae between the graft bed and graft, along with substantial graft thickness in X ray radiography.血液学检查包括红细胞沉降率(ESR)、C反应蛋白(CRP)、肝功能和血细胞计数。神经功能状态是根据Frankel分级系统进行分级。后凸角度是通过绘制两条直线来测量，一条线通过刚刚正常最上椎体的上缘，而另一条线通过正常最下椎体下缘。用Moon标准来评估骨融合情况，骨融合的特点是在X线片上可见植骨床与植骨块之间形成小梁，也可见植骨块大量增厚。,
25、Treatment StrategiesThe diagnosis was established by the presence of typical clinical and radiographic presentations, suggestive of STB in a resident from an endemic area who had an elevated ESR, CRP and a therapeutic response to anti-tubercular therapy. All patients were prescribed isoniazid (INH)
26、(5 mg/kg), rifampicin (10 mg/kg), ethambutol (15 mg/kg) and pyrazinamide (25 mg/kg) for 4 months duration, followed by rifampicin/ INH/pyrazinamide for at least a further nine months, until regression of symptoms, and resolution of laboratory and radiological abnormalities.治疗策略根据患者的典型临床表现和影像学结果做出诊断，
27、来自流行地区的居民如果有ESR和 CRP 升高，并且抗结核治疗有效，则提示为脊柱结核。所有患者均接受4个月的异烟肼（(INH)(5 mg/kg)，利福平(10 mg/kg)，乙胺丁醇(15 mg/kg)和吡嗪酰胺(25 mg/kg)等药物治疗，随后服用利福平、异烟肼和吡嗪酰胺至少9个月，直到症状消失、实验室和影像学异常均恢复正常。,Patients with progressive neurologic deficit received additional intravenous isoniazid (0.4g/day) for 3 days preoperatively. The basi
28、c principles of treatment for spinal tuberculosis that we referred to were as follows: the lesion which was limited vertebral body destruction, small amount of abscess, with neither progressive spinal cord and nerve root compromise, nor drug-resistant TB, could be treated conservatively; and the ind
29、ications for surgery included the evolving neurological deficit, spinal instability, severe kyphotic deformity, refractory disease, large paravertebral abscesses and epidural abscess compressing the dural sac.神经功能缺陷逐渐加重的患者术前3天额外静脉给予异烟肼(0.4g/天)。我们所提出的治疗脊柱结核的基本原则如下：局限性椎体破坏、少量脓肿形成、无进行性脊髓和神经根损伤和无耐药性结核病等
30、病变均可行保守治疗；手术适应证包括神经功能缺陷加重、脊柱不稳、严重后凸畸形、难治性疾病、巨大椎旁脓肿和硬膜外脓肿压迫硬膜囊等。,If the surgical lesion was confined to less than two adjacent segments, mono-stage posterior transforaminal debridement, interbody fusion and posterior instrumentation could be utilized; if the lesion involved more than 2 adjacent segme
31、nts or had large paraspinal abscess, anterior debridement and autogenous iliac bone graft or allograft bone could be added after posterior instrumentation. However, regarding the surgical treatment priority of each skipping lesion, the more serious lesion i.e. the one that resulted in more significa
32、nt neurological compromise was treated first. If two lesions both caused neurological compromise, the upper lesion was treated first.如果手术病变仅局限于小于两个相邻节段，则采用一期后路经椎间孔病灶清除、椎体间融合和后路内固定术；如果病变涉及到大于两个相邻阶段或伴有巨大椎旁脓肿，则后路内固定术后再补前路病灶清除、自体髂骨或同种异体骨植骨术。然而，考虑到每一个跳跃性病变的手术治疗优先性，病变越严重、导致患者的神经功能损伤则越明显，需第一个行手术治疗。如果两处病灶均引
33、起神经功能损害，则上部病变需优先治疗。,Operative ProcedureThe surgery was performed under general anaesthesia. During the first stage, posterior instrumentation was applied. As described previously, if the involvement was confined to mono-segment without mass paravertebral abscess, transforaminal debridement and inter
34、body fusion could be performed. Mild kyphosis could be corrected by postural reduction and the application of compressive, or translation correction forces during posterior instrumentation. The instrumentation was always extended 2 levels above and below the focus. Autogenous bone or allograft was s
35、elected for posterior fusion at designated segments that underwent decompression and focal debridement.手术流程手术在全身麻醉下进行。第一阶段采用后路内固定术，如前所述，如果病变局限于单节段并无巨大椎旁脓肿，则行经椎间孔病灶清除、椎间融合术。轻度后凸畸形可通过体位复位和使用压缩物来矫正，或后路内固定时转化为矫正力。内固定物经常延长到病灶上下两个节段，经减压和病灶清除后，选取自体髂骨或同种异体骨植入到指定的阶段中。,If the focus involved more than 2 adjace
36、nt segments or had large paravertebral abscess, anterior focal debridement and bone grafting could be performed, via thoracic, thoracolumbar, or peritoneal approaches for different lesions in a single stage or in two stages depending on patients conditions. Additionally, the leaping lesion without m
37、ass abscess and severe vertebral body destruction nor neurological compression could be left conservatively.如果病变累及大于两个相邻节段或伴有巨大椎旁脓肿，则采用前路病灶清除植骨融合术，根据患者实际情况选择经胸段、胸腰段或腹膜后入路行一期或二期手术。此外，无巨大脓肿形成和严重椎体破坏及神经功能损害的跳跃性病变可行保守治疗。,Postoperative Procedure and Follow-upThe drainage tube was removed when the drainag
38、e flow was less than 50 mL/24 h. The patients were allowed to start walking 2 weeks after surgery but the spine was immobilized with an orthosis for 3 months until bony fusion was achieved. Imageological examinations (X-ray) and hematologic parameters (ESR, CRP, liver function test) were performed a
39、t one month intervals in the first three months, three month intervals in the next nine months, at six month intervals in the second year and then once a year, along with the assessment of neurologic status, correction of deformity, and success of bone graft fusion. Clinical outcome was assessed pre
40、operatively and at the last follow-up visit using the Oswestry disability index (ODI) questionnaire.术后观察和随访引流量低于50 mL/24 h时拔出引流管，术后2周将允许患者下地行走，但要佩戴矫形器3个月固定脊柱，直至达到骨性融合。头3个月内每隔1个月复查影像学（X线）和血液学（ESR、CRP和肝功能试验）等检查，在接下来的9个月内每隔3个月复查一次，次年隔6个月复查一次，之后隔1年复查一次，每次复查时均进行神经功能状态、畸形矫正率和植骨融合成功率等方面的评估。术前和末次随访运用ODI指数调查
41、表进行临床疗效的评估。,DiscussionAs a result of AIDS and new drug-resistant strains, the resurgence of STB has sparked a flurry of activity toward the prevention and treatment of this condition. Nowadays, management strategies of STB include conservative therapy and various advanced surgical techniques. STB of
42、ten involves adjacent vertebras and the intervening disc, while leaping and remote lesion is not common and does not characterize the disease. Reviewing the literature, NSTB are mostly reported as episodic case reports in the mainstream academic journals. The incidence of NSTB is reported as 1.1% to
43、 71.4% , and it is 4.3% in our study.讨论艾滋病和新发耐药菌株导致的脊柱结核再手术率引起了一系列行动以预防和治疗这种情况。目前，脊柱结核的手术策略包括保守治疗和各种先进的手术技术。脊柱结核往往累及相邻椎体和椎间盘，而跳跃性和远端病灶并不常见，也不是本病的特征。通过文献复习发现， NSTB大多在主流学术期刊中发表为偶发病例报告。文献报道NSTB的发病率为1.1至71.4，而在我们的研究中的为4.3。,There is a minority of papers referring to the surgical treatment of NSTB. In 201
44、2, Shi et al. reported the results of 29 cases with NSTB treated with intervertebral focal surgery. These investigators obtained a mean correction rate of 59.5% with good bone fusion at the final follow-up. In the same year, Zhang et al. reported the clinical outcomes of posterior transforaminal tho
45、racic debridement, limited decompression, interbody fusion and posterior instrumentation for treatment of noncontiguous thoracic tuberculosis, which also achieved good clinical efficacy. So far, however, there is a paucity of information describing the comprehensive therapeutic strategies of NSTB. I
46、n this paper, we aim to evaluate the clinical efficacy of the surgical managements (posterior surgery and a combination of posterior and anterior surgery) for NSTB, and to discuss the relevant therapeutic strategies.报道NSTB手术治疗的文献很少，2012年Shi等人报道29例NSTB患者行椎体间病灶清除术的结果。这些研究人员在末次随访中获得了平均矫正率为59.5，且具有良好的骨性
47、融合。在同一年，Zhang等人报道对非连续性胸椎结核患者进行后路经椎间孔胸椎病灶清除、局部减压、椎间融合并后路内固定术，也取得了较好的临床疗效。然而，至今仍缺乏描述NSTB的综合治疗策略的数据。在本研究中，我们探讨评估NSTB手术治疗（后路手术和后前路联合手术）的临床疗效，并探讨相关的治疗策略。,The treatment principles of NSTB are basically derived from the experience in treating contiguous spinal tuberculosis. Surgery is indicated for patient
48、s with severe or evolving neurologic deficit despite antituberculous chemotherapy, persistence of symptoms despite adequate antitubercular therapy, spinal instability, and severe spinal deformity. Compare to single focus treatment, there are several noteworthy details in the treatment of NSTB. Multi
49、level surgical interventions of NSTB result in more surgical trauma and complications than that of single focus disease.NSTB的治疗原则基本上来自于连续性脊柱结核治疗的临床经验。手术治疗适应证有尽管行抗结核药治疗仍出现严重或进行性神经功能缺陷的患者，尽管给予充足的抗结核药治疗症状扔持续存在的患者，脊柱不稳、严重脊柱畸形的患者。与单纯病灶清除治疗相比，在NSTB治疗过程中有几个值得注意的细节。NSTB的多节段手术干预与单节段病变相比较，导致更多的手术创伤和并发症。,There
50、fore, surgical indications should be controlled more strictly for each lesion of patients. Severe surgical trauma and complications caused by multilevel surgical interventions should be reduced as much as possible, by application of minimized invasive surgical techniques and the preference of debrid
51、ement to radical surgery. In addition, during multilevel surgery, the upper lesion or the one with neurologic compression should be dealt with in priority. Whats more, staged procedures could be performed for patients with physical deterioration.因此，对患者的每个病变应严格控制手术指征。应用微创手术技术和彻底病灶清除术，应尽量减少多节段手术干预导致的严重创伤和并发症的发生。此外，在多节段手术过程中高位病变或神经压迫性病变应优先处理。更重要的是，对身体状况恶化的患者进行分期手术治疗。,
