RESUMO
Objective To explore the efficacy of T-cell spot test of tuberculosis infection(T-SPOT.TB)in the differential diagnosis of spinal tuberculosis(STB),and optimize diagnostic efficacy through the optimal cut-off value of receiver operating characteristic(ROC)curve.Methods Clinical data of patients with spinal infection in a hospi-tal from January 2010 to May 2019 were collected,including preoperative T-SPOT.TB test results,white blood cell count,C-reactive protein,erythrocyte sedimentation rate,procalcitonin,and tuberculosis antibodies,etal.Clinical diagnosis was conducted based on diagnostic criteria.The sensitivity and specificity of T-SPOT.TB in preoperative diagnosis of STB and other spinal infection was analyzed,and the diagnostic efficacy of the optimized T-SPOT.TB indicators was evaluated.Results A total of 132 patients were included in this study,out of whom 78 patients(59.09%)were diagnosed with STB,and 54(40.91%)were diagnosed with non-tuberculosis(non-TB)spinal in-fection.The sensitivity and specificity of T-SPOT.TB in differential diagnosis of STB were 67.68%and 66.67%,respectively.Univariate logistic regression analysis showed that compared with non-TB spinal infection,the OR va-lue of T-SPOT.TB test in diagnosing STB was 4.188(95%CI:1.847-9.974,P<0.001).The optimized T-SPOT.TB evaluation index through ROC curve to determine the optimal cut-off values of ESAT-6,CFP-10,and CFP-10+ESAT-6 for differential diagnosis of STB and non-TB spinal infection were 12.5,19.5,and 36,respec-tively,and area under curve(AUC)values were 0.765 6,0.741 5,and 0.778 6,respectively,all with good diag-nostic efficacy.CFP-10+ESAT-6 had the highest AUC.CFP-10+ESAT-6 specific spot count had higher efficacy in the diagnosis of STB,with a diagnostic accuracy of 75.56%,higher than 67.42%of pre-optimized T-SPOT.TB.Conclusion T-SPOT.TB test has high diagnostic efficacy in differentiating STB from non-TB spinal infection.Posi-tivity in T-SPOT.TB test,especially with spot count of CFP-10+ESAT-6 over 36,indicates a higher likelihood of STB.
RESUMO
Objectives:To explore the risk factors related to the prolonged postoperative length of hospital stay(LOS)in patients after spinal tuberculosis lesion removal and fusion with internal fixation,and to construct a nomogram prediction model,so as to provide a theoretical basis for the enhanced recovery management of spinal tuberculosis patients.Methods:The clinical data of 142 patients with spinal tuberculosis who underwent lesion removal and fusion with internal fixation in the Department of Orthopedics of the Affiliated Hospital of Zunyi Medical University between December 2018 and June 2023 were retrospectively analyzed.The patients were randomly divided into modeling group(n=96)and validation group(n=46)in a 2∶1 ratio.Setting the postoperative LOS>21d as the outcome variable for prolonged LOS,and taking age,gender,alcohol history,smoking history,hypertension,coronary heart disease,diabetes,anemia,postoperative hypoproteinemia,spinal cord injury,tuberculosis in other parts,bone destruction,blood transfusion,removal time of drainage,postoperative complications,operative time,blood loss,preoperative American Society of Anesthesiologists(ASA)score,postoperative ASA score,surgical incision length,pus formation,chemotherapy before surgery,and chemotherapy regimens as independent variables to develop univariate logistic regression model.The risk factors screened after univariate analysis were included for multivariate logistic regression model to determine the independent risk factors for LOS>21d after lesion removal and fusion with internal fixation in patients with spinal tuberculosis and to construct a predictive model for risk factors.The area under the curve(AUC)of receiver operating characteristics(ROC)curve was used to assess the the differentiation of the model;Calibration curve was used to assess the calibration situation of the model;Decision curve analysis(DCA)was used to assess the clinical value and influence of the model on actual decision-making process.Data of validation group was applied to draw ROC curve and calibration curve for external verification.Results:Univariate and multivariate analyses revealed that age(OR=1.040,95%CI:1.011-1.069),tuberculosis at other sites(OR=2.867,95%CI:1.157-7.106),and preoperative ASA score(OR=1.543,95%CI:1.015-2.347)were the independent risk factors for prolonged postoperative hospitalization in patients with spinal tuberculosis after lesion removal and fusion with internal fixation.The AUC of ROC curves of modeling group and validation group were 0.767(95%CI:0.671-0.863)and 0.720(95%CI:0.569-0.871),respectively,suggesting the predictive model had good predictive efficiency.The results of the calibration curve analysis demonstrated that the actual curve roughly resembled the ideal curve,and DCA curve revealed that the nomogram had superior clinical benefits.Conclusions:The spinal tuberculosis patients who are at older age,combined with other sites of tuberculosis,and with high preoperative ASA score are prone to prolonged LOS after lesion removal and fusion with internal fixation,and the risk prediction nomogram model developed accordingly has great predictive efficiency.
RESUMO
Objectives:To analyze the risk factors for prolonged length of stay(LOS)after lesion removal and bone graft fusion internal fixation in patients with spinal tuberculosis,and to develop and validate a predictive model.Methods:The clinical data of 152 patients with spinal tuberculosis who underwent lesion removal and bone grafting and fusion internal fixation at Honghui Hospital affiliated to Xi'an Jiaotong Univer-sity from February 2016 to December 2020 were retrospectively analyzed.The patients were divided into the prolonged LOS(PLOS)group and normal LOS(NLOS)group according to whether their postoperative LOS ex-ceeded the postoperative LOS of the 75th percentile of the overall study cohort.Univariate analyses were per-formed for gender,age,hypertension,diabetes,paraplegia,anticoagulation history,tuberculosis resistance,pre-operative anti-tuberculosis time,blood transfusion,surgical site,surgical approach,number of fused vertebrae,operative time,intraoperative blood loss(IBL),postoperative complications,blood transfusion cost,hospital cost,C-reactive protein(CRP),erythrocyte sedimentation rate(ESR),albumin(ALB),blood routine,and coagulation function in both groups.Based on Lasso regression,the risk factors significantly associated with postoperative LOS prolongation in spinal tuberculosis were selected and incorporated into a multivariate logistic regression analysis,and thereby a prediction model was established based on the results of multivariate logistic regres-sion analysis.The model was visualized by plotting a nomogram as a means of predicting the probability of risk for prolongation of LOS after spinal tuberculosis surgery.Internal validation of the model was performed using extended Bootstrap,where receiver operating characteristic(ROC)curves,calibration curves and decision curve analysis(DCA)were plotted to verify the discrimination,accuracy and clinical applicability.Results:The 152 patients enrolled in the study had a median LOS of 10d,and the 75%LOS was 14d.There were 96 patients in the PLOS group and 56 in the NLOS group.Univariate analysis showed that the differences in age,hypertension,diabetes,anticoagulation history,tuberculosis resistance,preoperative anti-tuberculosis time,surgical site,surgical approach,surgical time,IBL,postoperative complications,CRP,ESR,preoperative ALB,blood routine,and coagulation function were not statistically significant between the two groups(P>0.05),while the differences in gender,paraplegia,blood transfusion,number of fused vertebrae,blood transfusion cost,and hospitalization cost were statistically significant(P<0.05).The operative time,IBL,preoperative Hb,and preop-erative ALB were divided according to the Yoden index of ROC as the dividing point,and the cut-off value of operative time was 198(min),the cut-off value of IBL was 1000(mL),the cut-off value of preoperative Hb was 118(g/L),and the cut-off value of preoperative ALB was 38.8(g/L).Through Lasso regression model,the risk factors closely related to the prolongation of LOS after spinal tuberculosis were female,blood transfusion,the number of fused vertebrae≥3,operative time≥198min and IBL≥1000mL,preoperative Hb<118g/L and preoperative ALB<38.8g/L.Multivariate logistic regression analysis showed that female,number of fused ver-tebrae≥3,operative time≥198min and IBL≥1000mL were the risk factors for postoperative LOS prolongation in patients with spinal tuberculosis(P<0.05).A visual nomogram model for logistic regression was constructed,and the predictors included female,number of fused vertebrae,operative time,and IBL.A Bootstrap self-sampling of 1,000 times was performed to complete the internal validation of the model,with a C-index value of 0.882 and an area under the curve(AUC)of ROC of 0.884(95%CI:0.782 to 0.985).The calibration curve showed that the apparent curve of the model fitted well with the curve after deviation correction.The DCA curve showed that the threshold range of 0.2 to 0.9 had the greatest clinical benefit.Conclusions:Female,number of fused vertebrae≥3,operative time≥198min and IBL≥1000mL are the main risk factors for pro-longed LOS after lesion removal and bone graft fusion with internal fixation in patients with spinal tuberculo-sis,and the predictive model based on the above risk factors can help physicians to make clinical decisions and optimize the perioperative management.
RESUMO
Objectives:To investigate the clinical characteristics of noncontiguous spinal tuberculosis and the efficacy and prognosis of one-stage posterior debridement,bone graft fusion and internal fixation for the treat-ment of noncontiguous spinal tuberculosis.Methods:The clinical data of 31 patients with noncontiguous spinal tuberculosis treated in our hospital between July 2016 and May 2022 were retrospectively analyzed,in-cluding 18 males and 13 females,aged 49.5±27.5 years.There were 24 cases with 2 lesions and 7 cases with 3 lesions.Responsible vertebrae were clarified,and surgical lesions,fusion segments,and internal fixation methods were determined for each patient,so as to develop individualized surgical plans.The patients were followed up for 29.7±14.7 months(15-85 months).The operative time,intraoperative blood loss,and intraoper-ative and postoperative complications were recorded.Erythrocyte sedimentation rate(ESR)and C-reactive pro-tein(CRP)were examined and recorded before operation,at 1 month,3 months,and 1 year after operation,and at the last follow-up.Visual analogue scale(VAS)was used to evaluate the pain before operation,at 1 week,1 month,3 months,1 year after operation and at the last follow-up.Cobb angle was measured before operation,at 1 week after operation,and at the last follow-up.The American Spinal Injury Association(ASIA)classification was recorded before operation and at the last follow-up.Bridwell bone healing criteria were used to evaluate postoperative tuberculosis activity,symptom improvement,deformity correction,and bone healing at the last follow-up.Results:Among the 31 patients,20(65.4%)had only one lesion(65.4%),23(74.2%)were admitted to the hospital with pain as the main complaint,15(48.4%)had only pain symptoms during the course of the disease,11 cases(35.5%)had only one lesion with pain symptoms,and 18(58.1%)patients had at least one lesion missed at the initial diagnosis.All the patients were successfully operated.The operative time was 280.0±52.2min(165-330min),and blood loss was 567.7±332.0mL(150-1000mL).There were 4 cases of cerebrospinal fluid leakage and 3 cases of incision infection after operation,which were cured after symptomatic treatment.All foci of tuberculosis were cured without recurrence or retransmission.At pre-operation,1 month,3 months,1 year after surgery,and at the last follow-up,ESR was 41.5±26.3mm/h,16.3±13.4mm/h,12.5±6.3mm/h,11.4±5.2mm/h,and 9.2±3.1mm/h,and the levels of CRP were 32.8±23.2mg/L,7.3±5.6mg/L,6.2±4.1mg/L,5.1±3.7mg/L,2.8±2.3mg/L,which were both significantly lower after operation than those before operation(P<0.05).The VAS score was 6.4±2.4,2.4±1.7,2.3±1.3,1.6±0.9,0.9±0.7,and 0.4±0.3 before operation,at 1 week,1 month,3 months,1 year after operation,and at the last follow-up,which was significantly improved after operation when compared with that before operation(P<0.05).The Cobb angle was 25.7°±4.9° before operation,15.4°±2.1° at 1 week after operation,and 17.1°±2.3° at the last follow-up,and there were significant differences between the postoperative angles and preoperative angles(P<0.05).Among the 10 patients with preoperative neurological impairment,1 patient with preoperative grade A recovered to grade C at the last follow-up.Among the 4 patients with preoperative grade B,1 patient recovered to grade C and 3 to grade D.Of the 5 patients with preoperative grade C,2 recovered to grade D and 3 to grade E.All 42 bone graft lesions achieved bone fusion at 6-12 months after operation.At the last follow-up,34 lesions healed in Bridwell grade Ⅰ and 8 in Bridwell grade Ⅱ.Conclusions:For patients with noncontiguous spinal tuberculosis,one-stage posterior debridement,bone graft fusion and internal fixation is safe and efficient after determining responsible vertebrae and lesion features,which can obtain satisfactory results.
RESUMO
Objective To investigate the risk factors of postoperative complications in patients with spinal tuberculosis and analyze the value of prognostic nutritional index(PNI)in predicting these complications.Methods The clinical data of 156 patients with spinal tuberculosis who underwent surgery in the Affiliated Hospital of Zunyi Medical University from January 2018 to July 2022 were retrospectively analyzed.The patients were divided into a complication group and a non-complication group based on the presence or absence of postoperative complications.Baseline data,laboratory indicators,and surgery-related indicators were compared between the two groups.The risk factors for postoperative complications in spinal tuberculosis were analyzed,and receiver operating characteristic(ROC)curves were plotted to evaluate the predictive value of PNI for postoperative complications in the patients.Results Among all of 156 patients,68 contracted a total of 82 instances of postoperative complications,with an incidence of 43.59%.Coinfection with pulmonary tuberculosis,preoperative anti-tuberculosis treatment duration more than 4 weeks,surgical operation duration,and drainage days were identified as independent risk factors for postoperative complications in spinal tuberculosis(P<0.05).On the other hand,a higher PNI was found to be a protective factor against postoperative complications of the spinal tuberculosis(P<0.05).The area under the ROC curve for PNI predicting postoperative complications ofthe spinal tuberculosis was 0.805.Conclusion The risk of postoperative complications in patients with spinal tuberculosis is subject to such factors ascoexistence of pulmo-nary tuberculosis,preoperative anti-tuberculosis treatment duration,surgery duration,drainage duration,and preoperative PNI.Preoperative PNI has a certain value for predicting the postoperative complications in the patients.

Objectives:To observe the osteogenic properties and sustained release of 3D printed nano-hydroxyapatite(nHA)artificial bone loaded with a novel triple anti-tuberculosis drug combination(PaMZ)of Pretomanid(Pa),Moxifloxacin(M),Pyrazinamide(Z)and bone morphogenetic protein 2(BMP-2)in vivo.Methods:40 New Zealand rabbits were divided into four groups randomly and constructed spinal bone defect models.Group A(experimental group)implanted with 3D-printed PaMZ/BMP-2-loaded nHA artificial bone;group B(negative control group)implanted with blank nHA artificial bone;group C(positive control group)implanted with autologous iliac bone;group D(blank group)without bone grafting.The general conditions were observed,body temperature,weight,and liver and kidney function were monitored.The bone defect restoration was observed by spiral CT 3D reconstruction at the 4th,8th and 12th week postoperatively and was evaluated with CT-Hedberg scale;the gross observation of tissues and histopathological observation of the implants-bone defect interface were carried out at the 8th and 12th week postoperatively.100 SD rats were divided into two groups randomly,experimental group implanted with 3D-printed PaMZ/BMP-2-loaded nHA artificial bone,control group implanted with blank nHA artificial bone.The drug concentrations in the plasma and muscle tissue around the material at different time points was tested with high performance liquid chromatography.Results:All animal models were successfully constructed without incision infection or death.The body temperature,weight and liver and kidney function indexes of the experimental groups in the rabbit models were normal,with no statistical differences from those of the control groups(P>0.05).The CT-Hedberg score showed that there was no statistical difference between group A and group C at the 4th,8th and 12th week(P>0.05),however,there was statistical difference between all the other groups at different time points(P<0.05).The observation of the gross specimens at the 12th week after surgery showed that the artificial bone in group A was completely encapsulated or replaced by new bone,but there was still some artificial bone exposed in group B.Quantitative analysis of the total trabecular area at the implant-bone defect interface showed no statistical difference between groups A and C at the 8th and 12th week postoperatively(P>0.05),and a statistical difference between the remaining groups(P<0.05).No drug components were detected in the SD rat model control group,the three drugs Pa,M,Z in experimental group can be sustained-released in local tissues for at least 84d.The blood drug concentration was not detected at the initial time point after local implantation of the drug-loaded artificial bone,and the subsequent measured results were much lower than the local tissue drug concentration,and the two had a positive correlation.Conclusions:The 3D printed PaMZ/BMP-2-loaded nHA artificial bone has good osteogenic properties in vivo,the effect of restoring spinal bone defects is comparable to that of autologous iliac bone,which is better than that of HA artificial bone scaffold alone.Its sustained release behavior in vivo is satisfactory,and the blood drug concentration is much lower than the local tissue drug concentration.
RESUMO
RESUMEN La enfermedad de Pott o espondilodiscitis tuberculosa representa menos del 1% de los casos de tuberculosis. Sin embargo, el curso clínico indolente de esta enfermedad hace que su diagnóstico sea generalmente tardío, causando con ello la destrucción de las estructuras vertebrales. La deformidad resultante de la columna vertebral requiere tratamiento quirúrgico, el cual es complejo y requiere una estancia hospitalaria prolongada. Se describe el caso de un paciente varón de 52 años que fue diagnosticado de espondilodiscitis lumbar luego de la correspondiente evaluación clínica y estudios imagenológicos sin mostrar respuesta al tratamiento antibiótico empírico. Un abordaje transforaminal percutáneo, técnica mínimamente invasiva, permitió el diagnóstico de espondilodiscitis tuberculosa y la mejoría sintomática del paciente.
SUMMARY Pott's disease or tuberculous spondylodiscitis accounts for less than 1% of tuberculosis cases. However, the indolent clinical course of this condition leads to a generally delayed diagnosis and to the destruction of the vertebral structures. The resulting spinal deformity requires surgical treatment, which is complex and demands a prolonged hospital stay. In this report, we present the case of a 52-year-old male patient who was diagnosed with lumbar spondylodiscitis by clinical and imaging studies, without response to an empiric antibiotic treatment. Transforaminal percutaneous approach, a minimally invasive technique, allowed the diagnosis of tuberculous spondylodiscitis and a symptomatic improvement of the patient.
RESUMO
OBJECTIVE@#To observe the changes of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and nerve function in patients with spinal tuberculosis before and after surgery, explore the timing of surgical intervention, and evaluate its influence on surgical safety.@*METHODS@#A retrospective analysis was conducted on 387 patients with spinal tuberculosis who received surgical treatment from March 2012 to March 2017, including 278 males and 109 females, aged 12 to 86 years old with an average of (49.9±19.1) years. There were 64 cases of cervical tuberculosis, 86 cases of thoracic tuberculosis, 76 cases of thoracolumbar tuberculosis and 161 cases of lumbar tuberculosis. There were 297 patients with single segmental involvementand 90 patients with multiple segmental involvement. Among them, 62 cases presented neurological damage, and preoperative spinal cord neurological function depended on ASIA grade, 5 cases of grade A, 8 cases of grade B, 39 cases of grade C, and 10 cases of grade D. According to the duration of preoperative antituberculosis treatment, the patients were divided into group A (256 cases, receiving conventional quadruple antituberculosis treatment for 2-4 weeks before surgery) and group B (131 cases, receiving conventional quadruple antituberculosis treatment for more than 4 weeks before surgery). The two groups were compared in terms of gender, age, preoperative complicated pulmonary tuberculosis, lesion site, lesion scope, surgical approach, drug resistance and other general clinical characteristics. ESR, CRP, visual analogue scale(VAS), Oswestry Disability Index (ODI), Frankel grade and postoperative complications were observed.@*RESULTS@#All 387 patients were followed up for 12 to 36 (18.3±4.5) months. There were no significant differences in gender, age, preoperative pulmonary tuberculosis, lesion site, lesion range, surgical approach, preoperative drug resistance and other characteristics between two groups. A total of 32 patients in two groups did not heal after surgery, with an incidence rate of 8.27%. The VAS and spinal cord dysfunction index of the two groups were significantly improved after surgery (@*CONCLUSION@#After 2-4 weeks of anti tuberculosis treatment before operation, patients with spinal tuberculosis could be operated upon with ESR and CRP in a descending or stable period. In principle, patients with spinal tuberculosis and paraplegia should be treated as soon as possible after active preoperative management of the complication without emergency surgery.

BACKGROUND: Animal model experiments on bone tuberculosis showed that calcium sulfate artificial bone loading could slowly and permanently release antituberculosis drugs, increase local drug concentration, and repair local bone defects and promote bone fusion. OBJECTIVE: To evaluate the safety and efficacy of implantation of artificial bone with streptomycin sulfate and posterior percutaneous pedicle screw in the treatment of lumbar tuberculosis under transforaminal endoscopy after removal of lesions. METHODS: Twenty-eight patients with lumbar spinal tuberculosis who were treated in the First Affiliated Hospital of Guangxi University of Chinese Medicine from July 2016 to June 2019 were selected, including 10 males and 18 females, at the age of 36-69 years. Twelve patients in the experimental group received implantation of artificial bone with streptomycin sulfate and posterior percutaneous pedicle screw under transforaminal endoscopy after removal of lesions. Sixteen patients in the control group received bone graft fusion and internal fixation under anterior and posterior combined approach or bone graft fusion and internal fixation after posterior approach. Operation time, intraoperative blood loss, and hospital stay were recorded. At 3 months postoperatively and at the last follow-up, erythrocyte precipitation, C-reactive protein level and Cobb angle, visual analogue scale score, lumbar Japanese Orthopaedic Association score and Oswestry disability index score were compared between the two groups. The experiment was approved by the Ethics Committee of First Affiliated Hospital of Guangxi University of Chinese Medicine. RESULTS AND CONCLUSION: (1) The operation time, intraoperative blood loss and hospital stay in the experimental group were all less than those in the control group (P 0.05). (5) The results show that compared with the traditional posterior approach and combined anterior and posterior approaches in the treatment of lumbar tuberculosis, posterior lateral foramen endoscopic implantation of artificial bone with streptomycin sulfate combined with posterior percutaneous pedicle screw fixation can also achieve satisfactory clinical effect, and has the advantages of small trauma and rapid recovery.
RESUMO
Background: Spinal tuberculosis is the most common location of extra pulmonary tuberculosis. ATT alone may not be suitable in all situations, especially when treating patients with risk of instability, progression of neurologic deficit, and failure of medical treatment. Surgical intervention is a major treatment modality for symptom relief in spinal tuberculosis.Methods: The aim of this study was to assess the immediate post-operative outcome in surgically treated patients with dorsolumbar spine tuberculosis at Department of Neurosurgery Government Medical College, Thrissur. All operated patients of dorsolumbar spinal tuberculosis during 2014 September to 2019 august were included under study.Results: A total of 57 patients were included in the study. The mean age of the patient was 42.77 years. There were 40 males (70.2%) and 17 females (29.8%). 55 (96.5%) out of 57 patients were having sensory symptoms. 41 (71.9%) out of 57 patients were having motor symptoms. Bladder involvement 23 (40.4%) and bowel involvement 15 (26.3%) were also noted in the study. Sensory symptoms improvement in post-operative period was noted in 46 (80.7%). Motor symptoms improvement was observed in 23 (56.1%) out of 41. Bladder symptoms improved in 6 (26.1%) out of 23. There is improvement in clinical symptoms, neurological function immediately after surgery. Surgical patients have faster improvement and can be mobilized earlier. Improvement in sensory symptoms (96.5%), motor symptoms (56.1%) and bladder symptoms (26.1%) were noted in our study in the immediate post-operative period.Conclusions: There was significant immediate relief in symptoms and morbidity of patients undergoing surgical treatment for dorsolumbar spine tuberculosis.

BACKGROUND: Conventional anterior debridement and bone graft fusion for lumbar spinal tuberculosis have a great trauma, and bring more complications. The double titanium mesh support bone graft combined with posterior pedicle internal fixation reconstruction can significantly improve the prognosis of lumbar spinal tuberculosis. There is no clinical study to compare the efficacy between the two surgical methods. OBJECTIVE: To compare the efficacy of lumbar spinal tuberculosis via anterior double titanium mesh support bone graft combined with posterior pedicle internal fixation and conventional anterior debridement and bone graft fusion. METHODS: Case history data of 40 patients with lumbar spinal tuberculosis were retrospectively collected from the Department of Spinal Surgery, Mianyang Central Hospital, Southwest Medical University from May 2015 to March 2018. The patients were divided into experimental group and control group (n=20) according to the operation. Patients in the experimental group were treated with the anterior double titanium mesh support bone graft combined with the posterior pedicle screw fixation reconstruction. Patients in the control group were treated with anterior debridement and bone graft fusion. All patients signed the informed consent. This study was approved by the Hospital Ethics Committee. RESULTS AND CONCLUTION: (1) Lumbar spinal tuberculosis could be effectively treated with both surgical methods. (2) Compared with the control group, the operation time was shorter; the intraoperative blood loss was less; and the bone graft fusion was faster in the experimental group. (3) With prolongation of the postoperative time, the erythrocyte sedimentation rate and the sagittal Cobb angle of the lesion segment gradually decreased in the two groups. The erythrocyte sedimentation rate and the sagittal Cobb angle of the lesion segment in the experimental group were slightly lower than those in the control group. (4) After treatment, the classification of the American Spinal Cord Injury Association was improved in some patients. (5) The incidence of adverse reactions in the experimental group was lower than that of the control group. (6) The results suggest that double titanium mesh support bone graft combined with posterior pedicle internal fixation reconstruction can effectively improve the stability of the diseased vertebrae, and the treatment effect on lumbar spinal tuberculosis is better than conventional anterior lesion removal and bone graft fusion internal fixation.
RESUMO
OBJECTIVE@#To investigate the clinical effect of One-stage posterior debridement combined with lumbar-ilium fixation and bone graft fusion for the treatment of lumbosacral tuberculosis.@*METHODS@#The clinical data of 31 patients with lumbosacral tuberculosis treated by one-stage posterior debridement combined with lumbar-ilium fixation and bone graft fusion from January 2013 to February 2018 were retrospectively analyzed. There were 18 males and 13 females, aged from 18 to 77 years old with an average of (45.9±9.1) years. The lesion segment was form L to S. The preoperative ASIA grading showed that 2 cases were grade B, 17 cases were grade C, 12 were grade D. Pre- and post-operative C reactive protein (CRP), visual analogue scale (VAS), erythrocyte sedimentation rate (ESR), ASIA grade, lumbosacral angle and intervertebral space height were analyzed, the surgery complications, stability of internal fixation, bone fusion were observed.@*RESULTS@#All the 31 patients were followed up for 10 to 24 months with an average of (16.0±3.1) months. One patient with local infection and subcutaneous hydrops was cured by dressing change. Other 30 cases got primary healing without sinus formation and no recurrence of spinal tuberculosis. All the patients were cured, no internal fixation loosening and breakage were found. All bone fusion was successful with an average fusion time of (4.7±1.1) months. At the final follow-up, ESR and CRP were normal, the VAS was decreased from (6.13±1.21) points preoperatively to (1.92±0.57) pioints, the ASIA grading showed that 2 cases were grade C, 6 cases were grade D, and 23 cases were grade E. The lumbosacral angle and intervertebral space height was increased from preoperative (21.42±3.75) °, (7.84±0.41) mm to (27.21±3.12) °, (9.80±0.38) mm at the final follow-up, respectively.@*CONCLUSION@#One-stage posterior debridement combined with lumbar-ilium fixation and bone graft fusion is a practicable, effective and safe method for the treatment of lumbosacral tuberculosis. It can be recommended in clinical application.
RESUMO
Spinal tuberculosis is one of the most dangerous and destructive form of tuberculosis. Predisposing factors for spinal TB are same as that of pulmonary TB, which include poverty, overcrowding, illiteracy, malnutrition, diabetes mellitus, HIV infection, alcoholism, drug abuse. Though TB of cervical spine is rare but neurological deficits are more common as compared to lumbar spine. This is a case of 9 year old male child who developed neurological deficits after TB cervical spine. Panchakarma therapy along with oral medicines given for duration of one year provided significant relief in symptoms as- generalized weakness, muscle rigidity, muscle weakness. Further continuation of treatment is expected to bring more benefit.
RESUMO
Introduction: MRI is the most valuable method for detecting early disease and is preferred technique to define the activity and extent of infection followed by x–ray. Aim: To evaluate MRI as a valuable noninvasive diagnostic tool in spinal tuberculosis and to correlate with plain radiograph for the early detection of spinal tuberculosis. Material and method: This cross-sectional study was carried out on 40 patients who were suspected as cases of spinal tuberculosis. Plain X-ray were done before the MRI examination. Results: The comparison of X-ray and MRI for evaluating spinal TB on the basis of end plate irregularity, thecal sac compression, cord compression and cord changes was statistically highly significant. It was statistically significant on the basis of Disk Space Narrowing/Disk Involvement, paravertebral Widening/Psoas abscess and Posterior Element Involvement. X-ray when compared to MRI was found to have a sensitivity of 48.72% and a specificity of 100% in detection of end plate irregularities, sensitivity of 89.47% and specificity of 100% in detection of vertebral height reduction, sensitivity of 78.79% and specificity of 100% in detection of disk Space narrowing / disk Involvement and sensitivity of 28.57% and specificity of 92.31% in detection of paravertebral widening/psoas abscess. Conclusion: MRI is a better and more Informative imaging modality in evaluation of patients of Pott’s spine providing the diagnosis earlier than conventional methods.
RESUMO
Pedicle subtraction osteotomy (PSO) is a powerful tool for themanagement of sagittal misalignment. However, this procedure has a high rate of implant failure, particularly rod breakages. The four-rod technique diminishes this complication in the lumbar spine. The aim of the present study is to provide a case report regarding PSO and fourrod technique stabilization in the treatment of short-angle hyperkyphosis in the thoracolumbar (TL) junction. The authors describe the case of a patient with TL hyperkyphosis secondary to spinal tuberculosis treated with L1 PSO and fixation with a four-rod technique. There were no major surgical complications. The self-reported quality of life questionnaires (the Short-Form Health Survey 36 [SF-36] and the Oswestry disability index) and radiological parameters were assessed preoperatively, as well as 6, 12 and 24 months after surgery, and they showed considerable and sustained improvements in pain control and quality of life. No hardware failure was observed at the two-year follow-up.

STUDY DESIGN: Retrospective cohort.PURPOSE: To evaluate clinical outcomes, including pain and neurologic status, and to evaluate radiographic outcomes of patients treated with extended posterior decompression, posterior fixation, and fusion in different vertebral segments.OVERVIEW OF LITERATURE: The standard surgical treatment of spinal tuberculosis is radical debridement via anterior approach. However, this approach may lead to several serious complications. Meanwhile, extended posterior approach, the posterior surgical approach, involving the removal of posterior elements, ribs, and pedicles, is an alternative option that can achieve the aims of treatment in this disease and may reduce the serious complications from anterior approach.METHODS: The medical records and imaging of 50 patients admitted with spinal tuberculosis from January 2010 to June 2016 were reviewed. The Visual Analog Scale (VAS), Frankel grading scale, and kyphotic Cobb angle between the pre- and postoperative periods were used to evaluate the patients.RESULTS: The patients had significant improvement of VAS score in all the groups. The T/T–L, L, and L–S group scores improved from 7.2±1.5 to 1.7±1.2 (p<0.01), from 8.1±1.8 to 1.7±1.4 (p<0.01), and from 7.9±2.2 to 1.7±0.8 (p<0.01), respectively, and overall, the patient scores (n=50) improved from 7.8±1.4 to 1.7±1.3 (p<0.01). Ten patients (20%) had Frankel grade E preoperatively, which was improved to 38 patients (76%) postoperatively. A significant improvement of the kyphotic Cobb angle was observed when compared at the preoperative, early postoperative, and final follow-up period in the T/T–L, L, and L–S groups. The loss of correction angle in the LS group was 7.7°±4.3° at the final follow-up compared with the early postoperative correction angle at 9.1°±5.8°, with no statistically significant difference.CONCLUSIONS: Extended posterior decompression, posterior instrumentation, and fusion are effective methods of surgery for treatment of spinal tuberculosis involved in the thoracic, thoracolumbar, lumbar, and lumbosacral regions.

Objective To analyze the MRI features of Brucella spondylitis and spinal tuberculosis,to improve the ability of differential diagnosis. Methods MRI features of 22 cases with Brucella spondylitis and 26 cases with spinal tuberculosis confirmed by laboratory examination and operative pathology were analyzed retrospectively.Results Among 22 cases of Brucella spondylitis,1 7 cases occurred in the lumbar spine (1 3 cases in the lumbar 4 vertebrae),2 cases in the cervical spine,2 cases in the thoracic spine and 1 case in the sacral spine.1 9 cases had normal vertebral morphology,slight bone destruction and extensive edema,3 cases had severe vertebral wedge deformation, 16 cases had marginal bone hyperplasia.15 cases had slight changes in the intervertebral space,with narrow (or normal)or slight destruction of intervertebral disc,7 cases had severe narrowing or disappearance of intervertebral space and serious destruction of intervertebral disc. 13 cases had small paravertebral abscess,and 1 case had large paravertebral abscess.Among 26 cases of spinal tuberculosis,20 cases occurred in the lumbar spine (11 cases in the 4th and 5th vertebral bodies),5 cases occurred in the thoracic spine and 1 case occurred in the sacral spine,21 cases had severe vertebral wedge deformation due to bone destruction,9 cases had slight narrowing of intervertebral space, slight destruction of intervertebral discs,and 1 7 cases had obvious narrowing or narrowing of intervertebral space.7 cases had small paravertebral abscess and 1 6 cases had large paravertebral abscess with flowing phenomenon.Conclusion Vertebral morphology of Brucella spondylitis is basically normal,bone destruction is light and edema range is large,bone hyperplasia is common,slight narrowing (or normal)of intervertebral space occurs in intervertebral disc with less destruction,range of paravertebral abscess is limited.Bone destruction of spinal tuberculosis is heavy and edema range is small,vertebral body is easy to deform with no osteoporosis,significant stenosis (or disappearance)and severe disruption occur in intervertebral disc,paravertebral abscess is large often with flowing phenomenon.
RESUMO
Objective: To compare the short-term effectiveness of one-stage posterior debridement with non-structural bone graft and structural bone graft in the treatment of single segment thoracic tuberculosis. Methods: The data of 61 patients with single segment thoracic tuberculosis, who were treated by one-stage posterior debridement, bone graft fusion, and internal fixation between June 2011 and August 2015, was retrospectively analyzed. All of them, 26 cases were treated with structural bone graft (group A) and 35 cases with non-structural bone graft (group B). No significant difference was found between the two groups in gender, age, disease duration, comorbidity, involved segments, paravertebral abscess, and preoperative American Spinal Injury Association (ASIA) grade, C reactive protein (CRP), visual analogue scale (VAS) score, and Cobb angle of involved segments ( P>0.05). But the preoperative erythrocyte sedimentation rate (ESR) in group B was significantly lower than that in group A ( t=3.128, P=0.003). The operation time, intraoperative blood loss, hospitalization stay, VAS score, ESR, CRP, ASIA grade, postoperative complications, Cobb angle of involved segments and its correction rate and loss rate, and bone fusion time were recorded and compared between the two groups. Results: Compared with group A, group B had shorter operation time, less intraoperative blood loss, and longer hospitalization stay, showing significant differences ( P0.05). At last follow-up, the ASIA grade of the two groups significantly improved when compared with those before operation, and there was no significant difference between the two groups ( Z=-1.104, P=0.270). There were 9 cases and 10 cases of complications in groups A and B, respectively, and there was no significant difference ( χ2=0.254, P=0.614). The Cobb angle in group B was significantly higher than that in group A at 3 days after operation ( t=-2.861, P=0.006), but there was no significant difference in Cobb angle between the two groups at last follow-up ( t=-1.212, P=0.230). The postoperative correction rate and loss rate of Cobb angle in group A were higher than those in group B, and there was a significant difference in the loss rate between the two groups ( t=2.261, P=0.031). All patients got bone graft fusion and the bone fusion time of group B was significantly shorter than that of group A ( t=4.824, P=0.000). Conclusion: Non-structural and structural bone graft can both achieve good effectiveness in the treatment of single segment thoracic tuberculosis, but the former has the advantages of less surgical trauma and shorter fusion time.
