ABSTRACT
BACKGROUND: Spinal tuberculosis (STB) is a local manifestation of systemic infection caused by Mycobacterium tuberculosis, accounting for a significant proportion of joint tuberculosis cases. This study aimed to explore the diagnostic value of MRI combined with mannose-binding lectin (MBL) for STB. METHODS: 124 patients suspected of having STB were collected and divided into STB and non-STB groups according to their pathological diagnosis. Serum MBL levels were measured using ELISA and a Pearson analysis was constructed to determine the correlation between MBL and STB. ROC was plotted to analyze their diagnostic value for STB. All the subjects included in the study underwent an MRI. RESULTS: The sensitivity of MRI for the diagnosis of STB was 84.38% and specificity was 86.67%. The serum MBL levels of the patients in the STB group were significantly lower than the levels in the non-STB group. ROC analysis results indicated that serum MBL's area under the curve (AUC) for diagnosis of STB was 0.836, with a sensitivity of 82.3% and a specificity was 77.4%. The sensitivity of MRI combined with MBL diagnosis was 96.61%, and the specificity was 92.31%, indicating that combining the two diagnostic methods was more effective than using either one alone. CONCLUSIONS: Both MRI and MBL had certain diagnostic values for STB, but their combined use resulted in a diagnostic accuracy than either one alone.

BACKGROUND: Linezolid exhibits antibacterial activity against sensitive and drug-resistant strains of Mycobacterium tuberculosis. Knowledge on the distribution of linezolid in different types of bones in patients with spinal tuberculosis (TB) is lacking, which limits the pharmacokinetic and pharmacodynamic studies of linezolid. This study aimed to evaluate the distribution of linezolid in diseased and nondiseased bones in patients with spinal TB. METHODS: Spinal TB patients treated with linezolid-containing regimens and whose diseased and nondiseased bones were collected during surgery were enrolled retrospectively from January 2017 to February 2022. Blood, nondiseased bones, and diseased bones were collected simultaneously during the operation. Linezolid concentrations in the plasma, nondiseased bones, and diseased bones were subjected to high-performance liquid chromatography-tandem mass spectrometry. RESULTS: Seven eligible spinal TB patients, including one rifampicin-resistant case, were enrolled. Following a 600 mg oral administration of linezolid before surgery, the median concentrations of linezolid in plasma, nondiseased bone, and diseased bone of the seven patients were 8.23, 1.01, and 2.13 mg/L, respectively. The mean ratios of linezolid concentration in nondiseased bones/plasma, diseased bones/plasma and diseased bones/nondiseased bones reached 0.26, 0.49, and 2.27, respectively. The diseased bones/plasma presented a higher mean ratio of linezolid concentration than nondiseased bones/plasma, and the difference was statistically significant (t = 2.55, p = 0.025). Pearson's correlation analysis showed the positively correlation of linezolid concentrations in diseased and nondiseased bones (r = 0.810, p = 0.027). CONCLUSIONS: Linezolid exhibits a higher concentration distribution in diseased bones than in nondiseased bones.

BACKGROUND: In July 2023, our hospital confirmed one case of lumbar spine infected complicated by Mycobacterium tuberculosis and Cryptococcus neoformans. The patient was admitted due to lower back pain for 1 year and a hard lump for 3 months. Symptoms and signs: Dressing can be seen fixed on the lower back, with severe bleeding. When the dressing is removed, a hard and protruding lump with a size of 6 cm x 8 cm, a sinus tract can be seen near the mass, with a slightly red wound and a sinus depth of about 3 cm. Light red fluid can be seen flowing out. There are no symptoms such as redness, swelling, or heat in the rest of the lower back, and the patient has no other underlying diseases or surgical history. METHODS: Lumbar magnetic resonance imaging and lumbar CT examination; Percutaneous puncture lumbar vertebral biopsy was performed, and the biopsy tissue was subjected to pathological examination, mNGS (metagenomic next-generation sequencing), and acid-fast staining; Extract pus from the lump for fungal culture and ink staining, and identify the fungi through MALDI-TOF MS. RESULTS: Bone destruction and bone marrow edema in the L5 vertebral body, compression of the spinal canal at the L5 vertebral body level; The pathological results of the biopsy tissue indicate granulomatous lesions. The acid-fast staining of the tissue is positive, and the mNGS of the tissue indicates infection with Mycobacterium tuberculosis. A single fungus was cultured from pus and identified by MALDI-TOF MS as Cryptococcus neoformans. Clinically, isoniazid 0.3 g ivgtt + rifampicin 0.45 g qd po + ethambutol 0.25 g qd po + pyrazinamide 0.75 g qd po + fluconazole 0.3 g qd po was administered for treatment. After 11 days, there was slight pain at the incision site, and the original symptoms were significantly relieved. The wound dressing was fixed in place, dry and without obvious exudation. Improved and discharged, followed up for 3 months with no recurrence of the lesion. CONCLUSIONS: mNGS is an effective identification technique that can be used to accurately diagnose suspected infection cases. MALDI-TOF MS has significant advantages over traditional detection methods in shortening detection time. This case achieved satisfactory treatment results for patients through a reasonable treatment plan, which is of great significance for exploring the diagnosis and treatment of similar disease infections.

Craniocervical Pott's disease is rare, particularly in the pediatric population. The importance of motion preservation in this age group renders managing this disease even more challenging. The literature regarding craniocervical Pott's disease comes from endemic regions. Most authors will agree on early surgical intervention in cases of neurological compromise or severe instability, while patients with minimal symptoms will do well with conservative management. Controversy remains when patients are mildly symptomatic but with imaging findings concerning for significant instability. Here, we present the case of a 15-year-old male presenting with craniocervical tuberculoma with radiographic instability and advanced bony destruction without overt neurological deficits. He was managed with a rigid cervical collar and completed 1 year of anti-tuberculosis therapy. At 1-year follow-up, he had an intact range of motion, was pain-free, and remained neurologically intact. Although this case suggests good outcomes with conservative management are possible, more long-term follow-up is required to assess the need for delayed surgical intervention in this unique population.

PURPOSE: Spinal tuberculosis, if not promptly treated, can lead to kyphotic deformity, causing persistent neurological abnormalities and discomfort. Spinal cord compression can occur due to ossification of the ligamentum flavum (OLF) at the apex of kyphosis. Traditional surgical interventions, including osteotomy and fixation, pose challenges and risks. We present a case of thoracic myelopathy in a patient with post-tuberculosis kyphosis, successfully treated with biportal endoscopic spinal surgery (BESS). METHOD: A 73-year-old female with a history of untreated kyphosis presented with walking difficulties and lower limb pain. Imaging revealed a kyphotic deformity of 120° and OLF-induced cord compression at T8-9. UBE was performed under spinal anesthesia. Using the BESS technique, OLF was successfully removed with minimal damage to the stabilizing structures. RESULTS: The patient exhibited neurological improvement after surgery, walking on the first day without gait instability. Follow-up at 1 year showed no kyphosis progression or recurrence of symptoms. BESS successfully resolved the cord compression lesion with minimal blood loss and damage. CONCLUSION: In spinal tuberculosis-related OLF, conventional open surgery poses challenges. BESS emerges as an excellent alternative, providing effective decompression with reduced instrumentation needs, minimal blood loss, and preservation of surrounding structures. Careful patient selection and surgical planning are crucial for optimal outcomes in endoscopic procedures.

OBJECTIVE: To perform a meta-analysis comparing the MRI features of tuberculous and pyogenic spondylitis, using histopathological results and/or blood culture as the standard reference. MATERIALS AND METHODS: PubMed, Embase, Web of Science, and Cochrane Library were searched for English-language studies on the MRI features of tuberculous and pyogenic spondylitis published between January 2010 and February 2023. Risk for bias and concerns regarding applicability were assessed using the Quality Assessment of Diagnostic Accuracy Studies-2 tool. Pooled MRI features' proportions were calculated using a bivariate random-effects model. RESULTS: Thirty-two studies met the inclusion criteria: 21 for tuberculous spondylitis, three for pyogenic spondylitis, and eight for both. Of the nine informative MRI features comparing tuberculous spondylitis to pyogenic spondylitis, involvement of ≥ 2 vertebral bodies (92% vs. 88%, P = .004), epidural extension (77% vs. 25%, P < .001), paravertebral collection (91% vs. 84%, P < .001), subligamentous spread (93% vs. 24%, P < .001), thin and regular abscess wall (94% vs. 18%, P < .001), vertebral collapse (68% vs. 24%, P < .001), and kyphosis (39% vs. 3%, P < .01) were more suggestive of tuberculous spondylitis, while disc signal change (82% vs. 95%, P < .001) and disc height loss (22% vs. 59%, P < .001) were more suggestive of pyogenic spondylitis. CONCLUSION: Involvement of ≥ 2 vertebral vertebral bodies, soft tissue attribution, thin and regular abscess wall, vertebral collapse, and kyphosis were MRI features more common in tuberculous spondylitis, while disc signal change and height loss were more common in pyogenic spondylitis.

PURPOSE: To investigate the clinical efficacy and feasibility of the surgical treatment of thoracic spinal tuberculosis using one-stage posterior instrumentation, transpedicular debridement, and hemi-interbody and unilateral posterior bone grafting. METHODS: Fifty-six patients with thoracic spinal tuberculosis who underwent surgery performed by a single surgeon between September 2009 and August 2020 were enrolled in this study. Based on data from the erythrocyte sedimentation rate (ESR), Visual Analog Scale (VAS), and Cobb angle before surgery, after surgery, and at the most recent follow-up, clinical effectiveness was assessed using statistical analysis. The variables investigated included operating time, blood loss, complications, neurological function, and hemi-interbody fusion. RESULTS: None of the patients experienced significant surgery-associated complications. At the last follow-up, 23 of the 25 patients (92%) with neurological impairment showed improvement. The thoracic kyphotic angle was significantly decreased from 24.1 ± 9.9° to 13.4 ± 8.6° after operation (P < 0.05), and the angle was 14.44 ± 8.8° at final follow-up (P < 0.05). The Visual Analog Scale significantly decreased from 6.7 ± 1.4 preoperatively to 2.3 ± 0.8 postoperatively (P < 0.05) and finally to 1.2 ± 0.7 at the last follow-up (P < 0.05). Bone fusion was confirmed in 56 patients at 3-6 months postoperatively. CONCLUSIONS: One-stage posterior transpedicular debridement, hemi-interbody and unilateral posterior bone grafting, and instrumentation are effective and feasible treatment methods for thoracic spinal tuberculosis.

BACKGROUND AND OBJECTIVES: To explore the effect of nutrition management under ERAS concept in patients with spinal tuberculosis. METHODS AND STUDY DESIGN: The study was conducted in an orthopedic ward of a tertiary grade A special hospital in Beijing. The patients admitted from January 1, 2021 to June 27, 2023 were screened for inclusion. The qualified patients were randomized into experimental group or control group. The experimental group received perioperative nutrition management under the concept of ERAS while the control group received routine perioperative management in hospital. The data was collected on the next day of admission, the next day and the sixth day after operation, including laboratory indicators (lymphocyte count, hemoglobin level, etc), intraoperative bleeding volume, postoperative exhaust, defecation time, drainage volume, albumin infusion amount, nutritional risk score, length of stay, hospitalization costs, etc. Univariate analysis and multivariate analysis correcting for gender, age, and baseline values were performed using SPSS24.0. RESULTS: A total of 127 patients with spinal tuberculosis completed the study. Compared with the control group, the intraoperative blood loss (p=0.028) in the experimental group was significantly reduced, the postoperative exhaust time (p=0.012) and defecation time (p=0.012) were significantly shortened, and the nutritional status (p<0.001) was significantly improved. Besides, the results of multivariate analysis are robust after correcting potential confounding factors. CONCLUSIONS: Nutrition management under the concept of ERAS is helpful to reduce intraoperative bleeding, promote postoperative flatus and defecation, and improve nutritional status in patients with spinal tuberculosis, which may further improve their clinical outcome and prognosis.

BACKGROUND: Tuberculosis of the spine, a common manifestation of extra-pulmonary tuberculosis is characterized by vertebral destruction, paradiscal involvement, abscess collection and varying degrees of neurologic affectation. The primary disease caused by mycobacterium tuberculosis complex infects the lungs, lymph nodes of the mediastinum and gastrointestinal tract/ viscera with spinal involvement being secondary and caused by haematogenous spread. Tuberculous paraplegia arises as a complication of spinal involvement. AIM: To determine the outcome of operative intervention in tuberculous paraplegia. Methodology: This was a retrospective study involving 10 patients with tuberculous spinal involvement with varying degrees of neurological deficit as defined by both Tuli and ASIA grading. The VAS score, ESR, ASIA grade (both pre-op and post op), Tuli's grade (pre-op and post op) were used to analyze the therapeutic effects of the surgery. RESULTS: The mean pre-operative VAS score was 5.9 ±1.8, which significantly decreased to 2.2 ±1.3 six weeks post operatively. The mean pre-operative ESR and CRP was 78.9 ± 11.3mm/hr and 83 ± 13.5 respectively; which both showed a statistically significant decrease post-operatively, p<0.05. All cases achieved an increase of more than one ASIA grade post-operatively. CONCLUSION: Early surgical intervention is beneficial in patients with tuberculous spinal disease with neurologic involvement.

Spinal Tuberculosis ranks as one of the most common extrapulmonary varieties of tuberculosis. The study outlines the Extended Posterior Circumferential Decompression (EPCD) procedure for managing tuberculous spondylitis, a prevalent extrapulmonary form of tuberculosis. EPCD involves 360-degree dural decompression, anterior column debridement, and reconstruction following posterior instrumentation. This technique addresses both the infection and associated complications, particularly beneficial in cases with or without paraplegia. EPCD aims to improve outcomes by effectively tackling the pathology and restoring spinal stability. Purpose - to evaluate the functional and radiological outcome following Extended Posterior Circumferential Decompression in the tuberculosis of dorsal spine. A total of 10 patients were included after fulfilling inclusion criteria between July 2019 to December 2021, all patient underwent Extended Posterior Circumferential Decompression. All patients assessed using Visual analog scale (VAS), Medical Research council (MRC) grading, Frankel grading, Kyphus angle, Erythrocyte sedimentation rate (ESR), X-rays preoperative, immediate postoperative period and 9 month follow up. All patients were available for follow up, in this study mean age was 55.7±17.91. Out of 10 patients 60% were female, 40% was male. VAS, MRC grading, Frankel, ESR values, Kyphus angle showed better results in terms of functional and radiological outcome at 9 month follow up compared to preoperative values. The Employed Posterior Costotransversectomy Decortication (EPCD) technique grants ample ingress to both the lateral and anterior domains of the spinal cord, ensuring an equally efficacious decompression. This approach, characterized by its diminished morbidity, steers clear of the entanglements linked with thoracotomy and laparotomy. Moreover, it fosters prompt mobilization, thereby forestalling the adversities entailed by protracted immobility. With its capability for favorable kyphosis correction, adept surgical decompression, and enhanced functional outcomes, it stands as a beacon of surgical finesse.

BACKGROUND AND PURPOSE: Tuberculosis (TB) is the most fatal infectious disease worldwide. Approximately 24.6% of tuberculosis cases are extrapulmonary and predominantly affect the spine. It is difficult to diagnose spinal TB (STB). We aimed to evaluate the diagnostic performance of the Mycobacteria Growth Indicator Tube (MGIT)-960 culture, T-SPOT.TB, Xpert Mycobacterium tuberculosis complex (MTB)/resistance to rifampin (RIF), and Metagenomic Next-Generation Sequencing (mNGS) to detect STB. METHODS: We assessed 126 patients presumed to have STB using these four methods. The sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV) were calculated using clinical diagnosis as a reference. RESULTS: Of the patients, 41 were diagnosed with STB and 85 with non-STB. In the STB group, the sensitivity, specificity, PPV, and NPV of the MGIT-960 culture were 29.3% (12/41), 100% (85/85), 100% (12/12), and 74.6% (85/114), respectively. The sensitivity, specificity, PPV, and NPV of T-SPOT.TB were 92.7% (38/41), 82.4% (70/85), 58.5% (31/53), and 95.9% (70/73), respectively. The sensitivity, specificity, PPV, and NPV of the Xpert MTB/RIF assay were 53.7% (22/41), 100% (85/85), 100% (22/22), and 81.7% (85/104), respectively. The sensitivity, specificity, PPV, and NPV of mNGS were 39.0% (16/41), 98.8% (84/85), 94.1% (16/17), and 77.1% (84/109), respectively. The sensitivity, specificity, PPV, and NPV of mNGS + Xpert MTB/RIF were 73.2% (30/41), 100% (85/85), 96.8% (30/31), and 72.0% (85/118), respectively. The sensitivity, specificity, PPV, and NPV of the mNGS + T-spot assay were 97.6% (40/41), 100% (85/85), 67.9% (38/56), and 75.9% (85/113), respectively. Moreover, the sensitivity, specificity, PPV, and NPV of T-spot + Xpert MTB/RIF were 95.1% (39/41), 100% (85/85), 72.2% (39/54), and 81.0% (85/105), respectively. CONCLUSIONS: T-SPOT.TB is the most effective method for diagnosing STB; however, Xpert MTB/RIF is more reliable and can detect RIF resistance. Clinicians can use mNGS to identify pathogens in patients with spinal infections; these pathogens appeared to be more meaningful in guiding the clinical management of patients in the non-STB group. The combination of Xpert MTB/RIF and mNGS can improve the early diagnosis rate and drug resistance detection, reduce the diagnostic cycle, and provide early targeted anti-TB treatment for patients with STB.

BACKGROUND Thoracolumbar spinal tuberculosis is a severe form of extrapulmonary tuberculosis requiring precise management strategies. Traditionally, patients undergo a 2-4 week course of preoperative quadruple chemotherapy before surgery. However, recent clinical practices have begun exploring the potential of a short-course (1-7 days) intensive preoperative chemotherapy regimen. This study aims to examine and compare the clinical effectiveness of both approaches, offering critical insights into the optimal preoperative chemotherapy duration. MATERIAL AND METHODS In this retrospective analysis, we examined the clinical data from 123 patients with surgically treated thoracolumbar spinal tuberculosis. Patients were categorized into two groups based on the duration of preoperative chemotherapy: the short-course intensive chemotherapy group (n=53, 1-7 days) and the traditional quadruple chemotherapy group (n=70, 2-4 weeks). We gathered and compared the pertinent clinical data from both groups to ascertain differences in clinical efficacy. RESULTS All 123 patients underwent follow-up for a duration averaging 2.8±0.7 years. Five patients experienced postoperative recurrence. Patients reported significant pain alleviation and overall good clinical outcomes. Among patients with neurological dysfunction, neurological symptoms were ameliorated, and the implanted devices were found to be effective. Bony fusion was observed in all the bone grafting regions. CONCLUSIONS For patients suffering from thoracolumbar spinal tuberculosis exhibiting progressive neurological deterioration, surgical intervention is deemed feasible after a brief period (usually 1-7 days) of intensive preoperative antitubercular therapy. This finding suggests that short-course intensive preoperative chemotherapy may serve as a viable approach in managing such cases.

PURPOSE: Tuberculosis is one of the oldest diseases in human history, and spinal tuberculosis (STB) is the most common form of extrapulmonary tuberculosis. A large number of research has been conducted in this field. However, there has been no bibliometric analysis performed in recent years in STB. The aim of this study was to analyze trends and hotspots in research on STB. METHODS: Publications regarding STB between 1980 and 2022 were extracted from the Web of Science database. CiteSpace (V5.7.R2) and VOSviewer (1.6.10) were used to perform global analyses of the number of publications, countries, institutions, authors, journals, keywords, and cited references. RESULTS: A total of 1262 articles were published between 1980 and 2022. We observed rapid growth in the number of publications since 2010. Spine had the highest number of publications (47, 3.7%). Zhang HQ and Wang XY were key researchers. The Central South University published the most papers (90, 7.1%). China was the leading contributor in this field with 459 publications and 29 H-index. National partnerships are dominated by the USA, and there is a lack of active cooperation between other countries and authors. CONCLUSION: research on STB has achieved great progress, with an increasing number of publications since 2010. Surgical treatment and debridement are current research hots pots, and diagnosis, drug resistance, and kyphosis are likely research frontiers. Cooperation between countries and authors needs to be further strengthened.

PURPOSE: The diagnosis of STB is mainly based on clinicoradiological observations substantiated by bacterial culture, staining, Gene Xpert, and histopathology. The purpose of the study was to correlate these methods to evaluate the effectiveness in the diagnosis of STB. METHODS: A total of 178 clinicoradiologically suspected cases of STB were included in the study. The specimens for diagnostic workup were collected either during surgery or by CT-guided biopsy. All these specimens were tested for tuberculosis through ZN staining, solid culture, histopathology, and PCR. The sensitivity, specificity, PPV, and NPV of each test were calculated using histopathology as a gold standard. RESULTS: Out of the 178 cases, a total of 15 cases were excluded from this study. Among the remaining 163 cases, TB was diagnosed in 143 [87.73%] on histopathology, 130 [79.75%] on Gene Xpert, 40 [24.53%] on culture, and 23 [14.11%] on ZN stain. The sensitivity, specificity, PPV, and NPV of Gene Xpert were 86.71, 70, 95.38, and 42.42%, respectively. The sensitivity, specificity, PPV, and NPV of AFB culture were 27.97, 100, 100, and 16.26%, respectively. The sensitivity, specificity, PPV, and NPV of AFB stain were 16.08, 100, 100, and 14.29%, respectively. Gene Xpert showed a moderate agreement [Æc = 0.4432] with histopathology. CONCLUSION: No single diagnostic modality can ascertain the diagnosis, and it is desirable to have a combination of diagnostic batteries for better results. A combination of Gene Xpert and histopathology aids in early and reliable diagnosis of STB.

OBJECTIVES: This study aimed to establish a standard for selecting bone graft type for thoracolumbar spinal tuberculosis surgery based on the spinal instability neoplastic score (SINS). METHODS: Patients with thoracolumbar tuberculosis who underwent one-stage debridement posteriorly and instrumentation were divided into a structural bone graft group (SBG) (51 cases) and a non-structural bone graft group (NSBG) (54 cases) according to their SINS. SBG was performed when the SINS was ≥ 13 and NSBG was performed when it was 7 ≤ SINS ≤ 12. Baseline data, clinical outcomes, and imaging outcomes were collected and statistically analyzed between the two groups. RESULTS: Significant improvements in clinical and imaging outcomes were achieved in both groups. Compared to the SBG group, the operation time of the NSBG group was shorter, the intraoperative blood loss of the NSBG group was less, the bone fusion time of the NSBG group was faster. CONCLUSION: Non-structural and structural bone grafting can achieve comparable therapeutic effects in patients with spinal tuberculosis, and a suitable selection of bone grafts based on quantitative SINS will make full use of the advantages of different bone grafts.

BACKGROUND: Treating complex cases of spinal tuberculosis (STB) that involve multiple vertebral bodies and cause destruction of the spinal structure, kyphotic deformity, and acute nerve injury can be challenging. This report describes the course of treatment and 5-year follow-up of a complex case of multisegmental STB. CASE PRESENTATION: This report describes a case of tuberculosis affecting the vertebrae extending from thoracic 12 to lumbar 5 in a 60-year-old woman who suffered sudden paralysis in both lower extremities. The patient underwent emergency posterior paraspinal abscess clearance, laminectomy with spinal decompression. Partial correction of the kyphotic deformity via long-segment fixation from the T9 vertebral body to the ilium in a one-stage posterior procedure. The patient's neurological status was diagnosed as grade E on the American Spinal Injury Association (ASIA) scale after the one-stage operation. Following standardized 4-combination anti-tuberculosis drug therapy for three months in postoperative patients, the patient underwent two-stage transabdominal anterior abscess removal, partial debridement of the lesion and bilateral fibula graft support. One year after the two-stage operation, the patient's visual analog scale (VAS) score of back pain was 1 point, and the patient's erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) levels returned to normal. Five years after the second-stage operation, the Oswestry disability index (ODI) of patient quality of life was 14 points. There was a 4-degree change in the Cobb angle over five years. During the five-year follow-up period, the grafted fibula did not experience any subsidence. CONCLUSION: For patients with spinal tuberculosis and acute paralysis, it is essential to relieve spinal cord compression as soon as possible to recover spinal cord function. For lesions that cannot be debrided entirely, although limited debridement combined with anti-tuberculosis drug therapy has the risk of sinus formation and tuberculosis recurrence, it is much safer than the risk of thorough debridement surgery. In this case, an unconventional long-segment fibula graft, pelvis-vertebral support, was an effective reconstruction method.

BACKGROUND: To systematically assess the safety and effectiveness of titanium mesh grafting compared with bone grafting in the treatment of spinal tuberculosis. METHODS: Electronic databases, including PubMed, Embase, Web of Science, and Cochrane Library, were searched from their inception until April 2023. The outcome indicators for patients treated with titanium mesh grafting or bone grafting for spinal tuberculosis include surgical duration, intraoperative blood loss, graft fusion time, American Spinal Injury Association (ASIA) Spinal Cord Injury Grade E assessment, VAS score, lumbar pain score, post-graft kyphotic angle, and postoperative complications. The Newcastle-Ottawa Scale (NOS) and the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) approach were used for quality assessment and evidence grading of clinical studies. Funnel plots and Begg's test were employed for bias assessment. RESULTS: A total of 8 studies were finally included, comprising 523 patients, with 267 cases of titanium mesh fixation and 256 cases of bone grafting. The meta-analysis showed no significant statistical differences in surgical duration (Weighted Mean Difference (WMD) = -7.20, 95% Confidence Interval (CI): -28.06 to 13.67, P = 0.499), intraoperative blood loss (WMD = 16.22, 95% CI: -40.62 to 73.06, P = 0.576), graft fusion time (WMD = 0.97, 95% CI: -0.88 to 2.81, P = 0.304), ASIA Spinal Cord Injury Grade E assessment (Relative Risk (RR) = 1.03, 95% CI: 0.97 to 1.09, P = 0.346), and overall complications (RR = 0.87, 95% CI: 0.49 to 1.55, P = 0.643). Differences in VAS score, ODI lumbar pain score, and post-graft kyphotic angle between the titanium mesh grafting group and the bone grafting group were not significant within the 95% CI range. The rate of postoperative implant subsidence was slightly lower in bone grafting than in titanium mesh grafting (RR = 9.30, 95% CI: 1.05 to 82.22, P = 0.045). CONCLUSIONS: Both bone grafting and titanium mesh grafting are effective and safe for the surgery, with no significant statistical differences in the results. Considering the limitations of the present study, large-scale randomized controlled trials are warranted to further verify the reliability of this finding.

Lumbar vertebral tuberculosis presenting with a focal solitary osteolytic lesion is rare in spinal tuberculosis (TB) and the English literature describing this entity is scant. The differential diagnosis includes primary and secondary malignancies. In this report, we describe a case of 35-year-old woman who presented with low back pain and was found to have a focal L4 vertebral lytic lesion on MRI and CT. Whole body CT was carried out as a potential malignancy staging procedure and demonstrated lung lesions suggestive of TB. Her neurological and general examination were entirely normal. Her blood test was positive for QuantiFERON Gold. She was managed conservatively with anti-TB medications and serial imaging which showed evidence of resolution of the osteolytic lesion. Although it is unusual for TB to present as an isolated osteolytic vertebral body lesion, the possibility should always be considered in the differential diagnosis, along with neoplastic processes. Conservative medical management, in the absence of neurological deficits and deformity, is the main stay of management with a very good outlook.

STUDY DESIGN: Retrospective study. PURPOSE: The aim of this study was to develop a predictive model for determining perioperative blood transfusion in tuberculous spondylitis patients undergoing posterior decompression and instrumentation. BACKGROUND: Tuberculous spondylitis is a common infection found in the spine. This condition may result in the need of surgical treatment, especially when there is a delay in diagnosis with inadequate antituberculosis drug treatment. The procedure results in high amount of bleeding on many occasions, leading to the higher rate of intraoperative transfusion. We develop a predictive model that can be used to determine blood transfusion requirement in spinal tuberculosis surgery. METHODS: We reviewed the medical records of 83 tuberculous spondylitis patients who underwent posterior decompression and instrumentation. The clinical characteristics of the patients were analyzed using bivariate and multivariate regression test. The impact and strength of these variables was assessed to predict the probability of intraoperative red blood cell transfusion presence based on unstandardized beta, standard error, receiver operating characteristic, and confluence of sensitivity and specificity curve analyses. Furthermore, validation of this newly proposed predictive scoring system was performed using a set of 45 patients. RESULTS: The factors that significantly affect the need of blood transfusion during posterior spondylitis tuberculosis surgery were BMI (p = 0.005), pre-operative Hb (p < 0.001), number of affected segments (p = 0.042), and duration of surgery (p = 0.003). Our predictive model showed good sensitivity and specificity values based on a large area under the curve (0.913) and strong Pearson's r testing (correlation coefficient of 0.752). Validation set also resulted a large area under the curve (0.905) and strong correlation coefficient of 0.713. CONCLUSION: BMI, pre-operative Hb, number of affected segments, and duration of surgery became the significant factors which correlated to the presence of red blood cell transfusion in patients undergoing posterior spondylitis tuberculosis surgery. This predictive scoring system can be used to further adjust blood matching and inventory, determine intraoperative blood management, and ensure the safety of surgery in a comprehensive manner.

INTRODUCTION: Osteotomized debridement (OD) is increasingly used in the treatment of active thoracolumbar tuberculosis (TB). So far, no nomenclature has been established to describe the patterns of OD, and thus the surgical outcomes cannot be directly analyzed and compared among the patients treated with different extents of OD. The purpose of this study was to establish a reliable classification of OD for further study of spinal TB. MATERIALS AND METHODS: This was a multicenter retrospective study. The proposed classification included 6 grades of OD based on sagittal range of vertebral body destruction: grade 0 involves single-level intervertebral disc and adjacent superficial endplates; grade 1 involves adjacent endplates and vertebral bodies, but no pedicle is involved; grade 2 involves adjacent endplates, vertebral bodies, and a lower or upper pedicle; grade 3 involves adjacent endplates, vertebral bodies, and both of lower and upper pedicles; grade 4 involves an entire vertebral body and an adjacent lower or upper pedicle; grade 5 involves two continuous entire vertebral bodies. Two hundred and five patients with active thoracolumbar TB who underwent OD surgery were included, and all ODs were classified. The reliability of this classification was evaluated twice by 10 readers, and Fleiss kappa coefficients were calculated. RESULTS: In the 205 patients, 208 ODs were performed. Grade 2 OD was the commonest type (98/208, 47.1%), followed by grade 1 (50/208, 24.0%), grade 3 (26/208, 12.5%), grade 0 (20/208, 9.6%), grade 4 (8/208, 3.8%), and grade 5 (6/208, 2.9%). The average accuracy of the two readings was 86.2% and 90.1%, respectively. The intra-rater reliability for the classification was "almost perfect agreement" with a Fleiss kappa coefficient average of 0.92. The inter-rater reliability was "almost perfect agreement" with a coefficient average of 0.89 for two readings. CONCLUSIONS: This classification proved to be intuitive and reliable. The graded OD provides a platform for preoperative evaluation and allows comparative analysis of clinical outcomes in different extents of OD.
