Abstract
Pott's spine, commonly known as spinal tuberculosis (TB), is an extrapulmonary form of TB caused by Mycobacterium TB. Pott's paraplegia occurs when the spine is involved. Spinal TB is usually caused by the hematogenous spread of infection from a central focus, which can be in the lungs or another location. Spinal TB is distinguished by intervertebral disc involvement caused by the same segmental arterial supply, which can result in severe morbidity even after years of approved therapy. Neurological impairments and spine deformities are caused by progressive damage to the anterior vertebral body. The clinical, radiographic, microbiological, and histological data are used to make the diagnosis of spinal TB. In Pott's spine, combination multidrug antitubercular therapy is the basis of treatment. The recent appearance of multidrug-resistant/extremely drug-resistant TB and the growth of human immunodeficiency virus infection have presented significant challenges in the battle against TB infection. Patients who come with significant kyphosis or neurological impairments are the only ones who require surgical care. Debridement, fusion stabilization, and correction of spinal deformity are the cornerstones of surgical treatment. Clinical results for the treatment of spinal TB are generally quite good with adequate and prompt care.

Abstract
A healthy cervical spine with normal movement is the basis of many daily activities and is essential for maintaining a good quality of life. However, the alignment, fusion, and structure of the cervical spine can change for various reasons, leading to cervical deformity, mainly kyphosis. Approximately 5%‒20% of spinal infections in the cervical spine cause cervical deformity. The deformity can recover early; however, the disease's long-term existence or the continuous action of abnormal stress may lead to intervertebral fusion and abnormal osteophytes. Many gaps and controversies exist regarding infectious cervical deformities, including a lack of clear definitions and an acceptable classification system thereby requiring further research. Moreover, there is no consensus on the indications for postinfectious cervical deformity associated with <i>Mycobacterium tuberculosis</i>, <i>Staphylococcus aureus</i>, and Brucellosis. Therefore, we reviewed and discussed the incidence, clinical manifestations, changes, and treatment of infectious and inflammatory secondary cervical deformities from common to rare to provide a theoretical basis for clinical decision-making.

Abstract
Introduction Anterior cervical discectomy and fusion (ACDF) is a common operation for spinal surgery to treat a variety of cervical diseases. The postoperative infection rate of this procedure is extremely low, and adjacent segments are rarely involved. Tuberculosis (TB) is a common infectious disease that affects the spine in less than 1% of cases and is more common in the thoracolumbar and rarely cervical spine. Herein, for the first time, we report tuberculosis infection in adjacent segments after ACDF. Case presentation We report a 50-year-old patient with cervical spondylotic myelopathy (CSM) who was discharged from the hospital after receiving ACDF at the C3/4 level. Two months later, he was admitted to the hospital with neck pain and found to be infected with tuberculosis in C4/5. After 4 months of anti-tuberculosis treatment, the vertebral body was fused. Conclusion After ACDF, the adjacent cervical vertebrae were infected with TB but the infection was limited. We believe that the special vertebral blood supply and postoperative secondary blood-borne infection may lead to the occurrence of extrapulmonary tuberculosis.

Int Med Case Rep J 2022; 15:599-603. [PMID: 36281446 PMCID: PMC9587697 DOI: 10.2147/imcrj.s367615] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 10/07/2022] [Indexed: 11/07/2022] Open
Abstract
Background The occurrence of spinal fracture due to tetanus nowadays is extremely rare, as compared to the 1950s, since the widely available anti-tetanus and antispasmodic therapy. The spinal fracture in tetanus patients is usually reported in higher thoracic vertebrae, previously with a rate as high as 57.5%. Spondylitis is the most common form of skeletal tuberculosis (TB) and can cause a spinal fracture. In Indonesia, tetanus is still reported, while tuberculosis is still endemic; however, co-infection of both diseases is rarely reported. Case Presentation A 36-year-old male was brought to our hospital with jaw stiffness, accompanied by fever. A history of dental cavities was present, and 5 days prior, he experienced a fishing hook wound on his right index finger. There was no history of TB. Physical examination showed meningismus, 2 cm trismus, abdominal spasm, opisthotonus, and spontaneous muscle spasms, without dysautonomia. In the third week of hospitalization, while his tetanus condition improved, he complained of weakness in both legs. A thorough history taking revealed a history of backache for 3 years. A wedge-shaped fracture on his 11th and 12th thoracic vertebrae was observed on radiographic examination. A spinal TB diagnosis was made, and treatment was started. He refused to get spinal surgery, then went home with 4 out of 5 motor strength scale. After three months, he returned to his routine activity as a food hawker with no motor deficits. Conclusion Tetanus spinal fracture is extremely rare nowadays; a thorough history of spinal problems/medication is compulsory for anticipation. This patient’s spinal fracture was deemed due to a preexisting TB spinal infection that was precipitated by prolonged continuous tetanic spasm due to general tetanus.

Abstract
OBJECTIVE Cervical tubercular disease (CTB) is a rare pathology and constitutes 3-5% of all spinal TB. It includes atlantoaxial TB and sub-axial TB. As the literature evidence on this subject is scarce, majority of issues concerning CTB are still controversial. The current narrative review comprehensively discusses the various aspects related to CTB. Literature search: An elaborate search was made using keywords cervical tuberculosis, atlantoaxial tuberculosis, sub-axial tuberculosis, and cervico-thoracic tuberculosis, on pubmed and google (scholar.google.com) databases on 2 December 2020. We identified crucial questions regarding CTB and included relevant articles pertaining to them. RESULTS The initial search using keywords cervical tuberculosis, atlantoaxial tuberculosis, sub-axial tuberculosis, and cervico-thoracic tuberculosis yielded 4128, 76, 3 and 9 articles on 'pubmed' database, respectively. A similar search using the aforementioned keywords yielded 1,96,000, 2130, 117 and 728 articles on 'google scholar' database. The initial screening resulted in the identification of 178 articles. Full manuscripts were obtained for these articles and thoroughly scrutinised at the second stage. Review articles, randomised controlled trials and level 1 studies were given preference. Overall, 41 articles were included. CONCLUSION AATB and SACTB constitute 0.3 to 1% and 3% of spinal TB, respectively. The incidence of neuro-deficit in CTB is significantly more than other spinal TB. The general principles of management of CTB are similar to spinal TB elsewhere and medical therapy remains the cornerstone. Surgery is advocated in specific scenarios involving gross neuro-deficit, later stages of disease with significant bony/ligamentous disruptions, altered sagittal balance, drug resistance, and poor response to medications. The surgical approaches for AATB include anterior-alone, posterior-alone and combined approaches, although posterior access is the most preferred. Most of the studies on SACTB have supported the role of anterior approach. Additionally, posterior stabilisation may be necessary in specific scenarios. The overall long-term outcome in CTB is favourable.

Abstract
Objective The aim of this meta-analysis was to systematically evaluate the clinical efficacy and safety of short-course chemotherapy (≤ 6 months) compared with the standard therapy (9–18 months) for patients with spinal tuberculosis (TB) undergoing surgery in Chinese population. Methods In this meta-analysis, we searched electronic databases in the Cochrane Library, PubMed, Embase, China National Knowledge Infrastructure (CNKI), Chinese Science and Technology Periodical Database (VIP), and Wanfang data to determine the equivalence of short-course therapy (group A) and standard therapy (group B) for the drug therapy of TB in Chinese population up to December 24, 2019. Weighted mean difference (WMD), odds risk (OR), and their 95% confidence interval (CI) were calculated. All analyses of relevant outcome indicators were managed by using the Review Manager (RevMan) 5.2 software. Results This meta-analysis included six trials published involving 851 patients (group A, 397; group B, 454) with spinal TB. Results showed there were no significant differences between group A and group B in clinical cure rate (OR = 0.61; 95% CI 0.19–2.00, p > 0.05), change of erythrocyte sedimentation rate (ESR) (WMD = − 0.75; 95% CI − 3.33 to 1.83; p > 0.05) and bone graft fusion rate (OR = 2.32; 95% CI 0.36–14.81, p > 0.05). Meanwhile, there were fewer side effects (OR = 0.37; 95% CI 0.24–0.58, p < 0.05) in group A compared with group B. Conclusions The results of this meta-analysis showed that for patients with spinal TB undergoing surgery in Chinese population, short-course chemotherapy could be equivalent to the standard chemotherapy in terms of efficacy and have less side effects than the latter. Supplementary Information The online version contains supplementary material available at 10.1186/s13018-021-02375-9.

Abstract
Spinal tuberculosis often leads to neurological deficit and subsequent deterioration in functional outcomes. This review assesses the recent evidence on functional outcomes in spinal tuberculosis, highlighting functional recovery, assessment tools for functional measures, and associative factors for functional recovery. Using PubMed, a literature search was done using the terms “spinal tuberculosis,” “tuberculous spondylitis,” “tuberculous spondylodiscitis,” and “functional outcome” for original articles published between January 2010 and December 2019. A total of 191 search results were found. Detailed screening showed that 19 articles met the eligibility criteria: 13 of these focused on surgical methods, four on conservative management, and two on rehabilitation approaches. The outcome measures used for functional assessment were the Oswestry Disability Index (11 articles), Japanese Orthopaedic Association score (n=3), modified Barthel Index (n=2), Functional Independence Measure (n=2), and 36-item Short-Form Health Survey (n=1). Functional outcome was mainly affected by pain, spinal cord compression, and inpatient rehabilitation. No significant difference in functional outcome was found between conservative management and surgery for cases with uncomplicated spinal tuberculosis. Most studies focused on surgery as the mode of treatment and used pain-related functional measures; however, these assessed functional limitations secondary to pain, and not neurological deficits. Further studies may consider examining functional outcomes in spinal tuberculosis by utilizing spinal cord-specific functional outcome measures, to evaluate outcome measures as a prognostic tool, and to measure functional outcomes from specific rehabilitation interventions.

Abstract
PURPOSE OF REVIEW To review the most current diagnostic tools and treatment options for pyogenic and tubercular spine infection. RECENT FINDINGS Recent studies have focused on risk factors for failed nonoperative management in order to improve patient selection. Also, spine instrumentation and different grafting options have been safely utilized in the setting of an active infection without increasing the incidence of reoccurrence. However, the optimal surgical technique has yet to be established and instead should be patient specific. Spine infections include a broad spectrum of disorders including discitis, vertebral osteomyelitis, and spinal epidural abscess. It is paramount to recognized spine infections early due to the potential catastrophic consequences of paralysis and sepsis. The management of spine infections continues to evolve as newer diagnostic tools and surgical techniques become available. Magnetic resonance imaging with contrast is the imaging study of choice and computed tomography-guided biopsies are crucial for guiding antibiotic selection. Antibiotics are the mainstay of treatment and surgery is indicated in patients with neurological deficits, sepsis, spinal instability, and those who have failed nonoperative treatment.

Abstract
The objective of this study was to investigate the treatment and prognosis of patients with spinal tuberculosis in Guizhou province. A total of 863 patients with spinal tuberculosis admitted to our hospital from 2006 to 2017 were included in this study. All patients underwent standardized quadruple antituberculosis treatment. Eighty patients were lost to follow-up due to a change of their contact information or noncompliance. A total of 783 patients completed the follow-up. The average follow-up period was 20.33 ± 8.77 months (range: 6 to 38 months). Among these patients, 145 patients underwent conservative treatment, while 638 patients underwent surgical treatment. All patients in the surgery group were treated with lesion removal, bone graft fusion, and internal fixation. Preoperative and postoperative standard quadruple antituberculosis treatment was administered. The clinical efficacy was evaluated according to erythrocyte sedimentation rate (ESR), c-reactive protein (CRP), visual analogue scale (VAS), Cobb angle correction, neurological functional recovery, and interbody fusion with bone graft and tuberculosis outcome. A total of 608 patients achieved clinical cure. The symptoms, physical signs, blood tests and imaging findings were improved in 143 patients. Twenty patients showed refractory clinical symptoms, and 12 patients had local tuberculosis recurrence. Conservative and surgical treatments are the mainstream treatments for spinal tuberculosis. According to the patients' individual conditions, individualized treatments should be used to achieve good efficacy. Standardized antituberculosis treatment should be applied over the course of spinal tuberculosis.

Abstract
Southwest China has a high burden of spinal tuberculosis (TB). Few large case studies of spinal TB in southwest China have been conducted. This study investigated the features of 921 patients who were treated for spinal TB at a general hospital in southwest China between 2001 and 2016. Demographic data, clinical data, laboratory data, imaging findings, treatment methods, and outcomes of patients who were admitted to the hospital for spinal TB were reviewed retrospectively. The annual incidence of spinal TB increased throughout the study period. The greatest number of patients were 41 to 50 years old (22.04%). Local pain was the most common symptom (97.8%). A significant difference in the duration of symptoms was observed between rural populations (28.40 months) and urban populations (10.17 months) (P=.041). Of the patients, 32.68% had a normal erythrocyte sedimentation rate and 25.84% had a normal C-reactive protein level. The lumbar spine was the most commonly involved spinal site (44.77%), followed by the thoracic spine (43.60%). All of the patients underwent chemotherapy, and 77.10% of patients underwent surgery. Most of the patients were cured, with the exception of 2.19% of patients who discontinued chemotherapy after early improvement of clinical status. Spinal TB is still a major public health problem in southwest China. Chemotherapy and surgery can yield satisfactory outcomes with timely diagnosis and long-term treatment. It is urgent to increase the attention paid to spinal TB and improve knowledge of this disease among the general public, especially in southwest China. [Orthopedics. 2017; 40(6):e1017-e1023.].

Abstract
BACKGROUND Cervical spinal tuberculosis is relatively common in some developing countries. It erodes vertebrae and discs, which sometimes results in cervical kyphosis and myelopathy. However, to our knowledge, no studies have evaluated improvements to patient-reported outcomes among patients who undergo surgical cervical sagittal realignment after kyphotic cervical spinal tuberculosis has been treated by débridement and reconstruction. QUESTIONS/PURPOSES (1) Can a spine with kyphotic cervical spinal tuberculosis be returned to normal alignment and fused successfully? (2) Will patient-reported outcomes be improved with this intervention? (3) Are patient-reported outcomes correlated with realignment? METHODS Forty-six patients with kyphotic cervical spinal tuberculosis were evaluated in this retrospective study. We generally performed surgery on patients with this condition when patients with cervical spinal tuberculosis presented with cervical kyphosis with or without neurologic deficits. Patients who did not meet these criteria were treated with other surgical procedures during the study period. Study patients were evaluated with cervical imaging, patient-reported outcomes questionnaires (Neck Disability Index [NDI], and the Japanese Orthopaedic Association [JOA] score), and physical examinations. Scores were collected by fellows preoperatively and at followup. No patient died during the followup. The mean followup was 26.8 months (range, 20-35 months). Preoperative and 2-year followup radiologic parameters were measured, including C0-2 Cobb angle, C2-7 Cobb angle, C2-7 sagittal vertical axis, center of gravity (CG) to C7 sagittal vertical axis (CG-C7 sagittal vertical axis), thoracic inlet angle, T1 slope, and neck tilt. The correlations between cervical alignment and the NDI and JOA score were analyzed. Factors correlated with the NDI and JOA score improvements were identified by multiple stepwise regression analysis. CT was used to assess bone fusion after surgery. RESULTS All 46 patients showed bone fusion on CT scans. The preoperative C0-2 Cobb angle improved after surgery (mean difference, 5.0°; 95% CI, 2.3°-7.7°; p = 0.0068), as did C2-7 Cobb angle (mean difference, -33°; 95% CI, -35° to -31°; p = 0.0074), C2-7 sagittal vertical axis (mean difference, -28 mm; 95% CI, -30 mm to -26 mm; p = 0.0036), CG-7 sagittal vertical axis (mean difference, -26 mm; 95% CI, -28 mm to -24 mm; p = 0.0049), T1 slope (mean difference, 6.0°; 95% CI, 3.7°-8.3°; p = 0.0053) and the thoracic inlet angle (mean difference, 8.0°; 95% CI, 3.7°-12°; p = 0.0072). With the numbers available, the neck tilt angle did not improve (mean difference, -0.2°; 95% CI, -1.0° to 0.6°; p = 0.079). The preoperative NDI of 34 ± 5.1 decreased to 17 ± 4.6 (p = 0.0096) at followup. Improvements in NDI were correlated with the magnitude of correction of the cervical deformities, including C0-2 Cobb angle (r = -0.357, p = 0.007), C2-7 Cobb angle (r = 0.410, p = 0.002), T1 slope (r = -0.366, p = 0.006, thoracic inlet angle (r = -0.376, p = 0.005), C2-7 sagittal vertical axis (r = 0.450, p = 0.001), and CG-C7 sagittal vertical axis (r = 0.361, p = 0.007). The JOA score improved to 13 ± 2.6 from 7.2 ± 1.9, which did not correlate with postoperative cervical realignment. After controlling for potential confounding variables like Cobb angles and T1 slope, we found C2-7 sagittal vertical axis was the most influential factor correlated with NDI improvement (r = 0.450, p = 0.002). CONCLUSION When treating kyphotic cervical spinal tuberculosis by débridement, decompression, and reconstruction, more attention should be drawn to realigning the cervical spine, in particular to restoring the C2-7 sagittal vertical axis. However, how best to restore the C2-7 sagittal vertical axis and cervical alignment in a kyphotic cervical spine needs further study. LEVEL OF EVIDENCE Level III, therapeutic study.

Abstract
BACKGROUND Thoracic spinal tuberculosis (TST) is a dangerous disease. Besides antituberculosis chemotherapy, surgery is also necessary for treating TST. To date, no study has focused on the prognostic factors for recovery of patients after surgery for TST. METHODS From 2001-2016, 237 patients who underwent surgery for TST in our department were included in this study. Japanese Orthopedic Association score was used to assess recovery after surgery. Kaplan-Meier method and Cox regression analysis were employed to identify the significant prognostic factors. RESULTS Univariate analysis demonstrated that diabetes, paralysis, kyphosis, duration of symptoms (≥3/<3 months), and number of involved vertebrae (>2/≤2) were identified as potential prognostic factors responsible for recovery after surgery for TST. Multivariate analysis suggested that paralysis, duration of symptoms (≥3/<3 months), and number of involved vertebrae (>2/≤2) were identified as the significant prognostic factors responsible for recovery after surgery for TST. CONCLUSIONS This study supports the previously published evidence that nonparalysis, shorter duration of symptoms, and fewer involved vertebrae are favorable prognostic factors for recovery after surgery for TST. For a better recovery effect, the key points for treating TST were timely diagnosis and treatment. It is urgent for government to arouse attention and popularize the knowledge of spinal tuberculosis.

World Neurosurg 2017; 104:660-667. [PMID: 28546121 DOI: 10.1016/j.wneu.2017.05.076] [Citation(s) in RCA: 5] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2017] [Revised: 05/11/2017] [Accepted: 05/12/2017] [Indexed: 10/19/2022]
Abstract
BACKGROUND Anterior debridement/bone grafting/posterior instrumentation is a common selection for the treatment of lumbar spinal tuberculosis (LST). To date, no study has focused on the prognostic factors for recovery after this surgery. METHODS We included 144 patients who experienced anterior debridement/bone grafting/posterior instrumentation for LST. The recovery rate based on the Japanese Orthopedic Association (JOA) score was used to assess recovery. The Kaplan-Meier method and Cox regression analysis were used to identify the prognostic factors for recovery postoperatively. For the prognostic factors worth further consideration, the changes in JOA scores within the 24-month follow-up period were identified by repeated-measures analysis of variance. RESULTS Paralysis/nonparalysis, duration of symptoms (≥3/<3 months), number of involved vertebrae (>2/≤2), and posterior open/percutaneous instrumentation were identified as prognostic factors for recovery postoperatively. The prognostic factor of open/percutaneous instrumentation was then further compared for potential clinical application. Patients in the percutaneous instrumentation group achieved higher JOA scores than those in the open instrumentation group in the early stages postoperatively (1-3 months), but this effect equalized at 6 months postoperatively. Patients in the open instrumentation group experienced longer operation time and less cost than those in the percutaneous instrumentation group. CONCLUSIONS Nonparalysis, shorter symptom duration, fewer involved vertebrae, and posterior percutaneous instrumentation (compared with open instrumentation) are considered favorable prognostic factors. Patients in the percutaneous instrumentation group achieved higher JOA scores than those in the open instrumentation group in the early stages postoperatively (1-3 months), but no significant difference was observed in long-term JOA scores (6-24 months).
