Absceso del psoas secundario a tuberculosis vertebral / Psoas abscess secondary to vertebral tuberculosis

Introducción: Presentamos el caso de un paciente masculino de 29 años con absceso del psoas bilateral secundario a tuberculosis vertebral. El absceso del psoas no suele ser frecuente en pacientes con tuberculosis extrapulmonar y principalmente con la enfermedad de Pott, pero cuando aparece suele ser subdiagnosticado debido a la inespecificidad de sus manifestaciones clínicas. Objetivos: Abordaje clínico-quirúrgico del absceso del psoas secundario a la tuberculosis vertebral, o Mal de Pott. Materiales y métodos: Búsqueda bibliográfica efectuada en pubmed. Relato de caso clínico: registro clínico y fotográfico, evolución, presentación de: resultados laboratoriales y de métodos auxiliares y tratamiento. Resultados: Síntomas presentados por un paciente de 29 años: dolor abdominal, dolor en miembro inferior, lumbalgia, expectoración sanguinolenta, dificultad en la deambulación, y cuadro respiratorio previo y síntomas constitucionales como pérdida de peso, anorexia, astenia. Con base en la anamnesis, examen físico y hallazgos en exámenes específicos, se pudo lograr el diagnóstico de absceso del psoas secundario a la tuberculosis vertebral. El tratamiento farmacológico seguido fue el propuesto por la OMS para la Tuberculosis más punción del absceso para drenaje y cultivo del mismo, con catéter multipropósito. El paciente tuvo una evolución favorable y posterior a la intervención neuroquirúrgica fue dado de alta. Conclusión: El paciente evolucionó de forma favorable, y las medidas aplicadas en el desarrollo de su enfermedad, fueron oportunas.

Introduction: We present de case of a 29 year old male patient with bilateral psoas abscess secondary to vertebral tuberculosis. Psoas abscess is not usually frequent in patient with extra-pulmonary tuberculosis and specially Pott's disease, but when it appears it is usually under diagnosed due to non-specificic clinical manifestations. Objectives: Clinical-surgical approach to psoas abscess secondary to vertebral tuberculosis, or Pott's disease. Materials and methods: Bibliographic search carried out in pubmed. Case report: clinical and photographic record, evolution and presentations of laboratory results, diagnostic auxiliary methods and treatment. Results: Symptoms presented by a 29 years old patient: abdominal pain, lower limb pain, low back pai, bloody expectoration, difficulty walking and previous respiratory and constitutional symptoms sucha as weight loss, anorexia, asthenia. Based on the clinicalhistory, physical examination and findins in specific tests, the diagnosis of psoas abscess secondary to vertebral tuberculosis could be achieved. The pharmacological treatment followed was the one proposed by WHO for tuberculosis, plus the drainage and culture of the abscess, with a multipurpose catheter. The patient had a favorable evolution and after the neurosurgical intervetntion he was discharged. Conclusion: The patient evolved favorably, and the measures applied in the development of his disease were appropriate.

The Relative Lymphocyte Count is Lower when the Etiological Agent in Pott Disease is Successfully Isolated / O número relativo de linfócitos é menor quando o agente etiológico da doença de Pott é isolado com sucesso

Abstract Objective To describe the clinico-epidemiological, laboratory, and radiological characteristics of tuberculous spondylodiscitis in the Brazilian population, and to assess whether there are differences between patients in whom the etiological agent in Pott disease was isolated or not. Methods Patients diagnosed with tuberculosis (TB) of the spine (Pott disease) underwent follow-up between 2009 and 2019 at a quaternary hospital and were divided into 2 groups: successful isolation (SI) of the etiological agent (through bacilloscopy, culture, or positive molecular rapid test) and unsuccessful isolation (UI) of the etiological agent. Results From a total of 26 patients diagnosed with TB of the spine, 21 (80.7%) were male, with a mean age of 40 ± 22.5 years. The average lymphocyte counts were higher in the UI group (25.35 ± 13.08; p= 0.025) compared to the SI group (14.18 ± 7.48). Moreover, the monocyte/lymphocyte ratio was lower in the UI group (0.39 ± 0.22; p= 0.009) than in the SI group (0.89 ± 0.65). Relative lymphocyte counts higher than or equal to 16.7 had a sensitivity of 76.9% and specificity of 62.5% in the UI group. Values higher than or equal to 0.58 for the monocyte/lymphocyte ratio showed a sensitivity of 84.6% and specificity of 75.0% in the UI group. Conclusion No differences were observed regarding the clinico-epidemiological and radiological characteristics of the two experimental groups. However, the UI group had higher lymphocyte counts and a lower monocyte/lymphocyte ratio.

Resumo Objetivo Descrever as características clínico-epidemiológicas, laboratoriais e radiológicas da espondilodiscite tuberculosa na população brasileira e avaliar se há diferenças entre pacientes em que o agente etiológico da doença de Pott foi isolado ou não. Métodos Os pacientes diagnosticados com tuberculose (TB) da coluna (doença de Pott) foram acompanhados em um hospital quaternário entre 2009 e 2019 e divididos em 2 grupos: isolamento positivo (IP) do agente etiológico (por baciloscopia, cultura ou teste rápido molecular positivo) e isolamento negativo (IN) do agente etiológico. Resultados De um total de 26 pacientes com diagnóstico de TB da coluna, 21 (80,7%) eram do sexo masculino, e a média de idade era de 40 ± 22,5 anos. As contagens médias de linfócitos foram maiores no grupo IN (25,35 ± 13,08; p= 0,025) do que no grupo IP (14,18 ± 7,48). Além disso, a relação monócito/linfócito foi menor no grupo IN (0,39 ± 0,22; p= 0,009) do que no grupo IP (0,89 ± 0,65). O número relativo de linfócitos maior ou igual a 16,7 teve sensibilidade de 76,9% e especificidade de 62,5% no grupo IN. A razão monócito/linfócito maior ou igual a 0,58 teve sensibilidade de 84,6% e especificidade de 75,0% no grupo IN. Conclusão Não observamos diferenças em relação às características clínico-epidemiológicas e radiológicas entre os dois grupos experimentais.

Introduction. Evaluer les résultats du traitement chirurgical du Mal de Pott et de ses séquelles au Centre hospitalier de l'ordre de Malte de Dakar. Patients et méthodes. Nous présentons les résultats préliminaires d'une série consécutive de 23 patients (13 hommes et 10 femmes) d'âge moyen de 32,35 ans [6 ­70 ans] présentant des Maux de Pott ou de leurs séquelles nécessitant un traitement chirurgical. L'échelle d'incapacité d'Oswestry, l'échelle visuelle analogique et le score ASIA ont été utilisés pour l'évaluation clinique. Les radiographies pré opératoires, post opératoires et au recul ont été utilisés pour les résultats anatomiques. Tous ces patients ont été opérés selon trois stratégies opératoires sur une période de 67 mois (Avril 2014- Novembre 2019). Nous avons réalisé une laminectomie arthrodèse postérieure dans 52,2% ; une laminectomie plus OTP et arthrodèse postérieure dans 43,5% ; une discectomie et hémicorporectomie avec arthrodèse antérieure par plaque vissée de Roy Camille à l'étage cervical dans 4,3%. Résultats. La symptomatologie était dominée par la douleur rachidienne, la cyphose et les troubles neurologiques. La cyphose post opératoire était significativement améliorée (la moyenne passe de 48,52° en pré opératoire à 17,09° en post opératoire). On a obtenu 100% de fusion vertébrale. On note une nette amélioration de la douleur rachidienne (avec une baisse au recul de 55,44 points pour l'OID et de 5,66 pour l'EVA) ; 78,3% des patients étaient très satisfaits, 17,4% satisfaits et 4,3% mécontents. Conclusion. Le traitement chirurgical du Mal de Pott et de ses séquelles a fortement amélioré les rachis au Centre hospitalier de l'Ordre de Malte.

We present the preliminary results of a consecutive series of 23 patients (13 men and 10 women) with an average age of 32.35 years [6-70 years] presenting with Pott's disease or its sequelae requiring treatment. surgical treatment. Oswestry Disability Scale, Visual Analogue Scale and ASIA score were used for clinical assessment. Preoperative, postoperative and followup radiographs were used for anatomical results. All these patients were operated according to three operating strategies over a period of 67 months (April 2014- November 2019). We performed posterior laminectomy-arthrodesis in 52.2%; laminectomy plus OTP and posterior arthrodesis in 43.5%; discectomy and hemicorpectomy with anterior arthrodesis by Roy Camille screwed plate at the cervical level in 4.3%. Results. The symptomatology was dominated by spinal pain, kyphosis and neurological disorders. Postoperative kyphosis was significantly improved (the average goes from 48.52° preoperatively to 17.09° postoperatively). We got 100% spinal fusion. There is a clear improvement in spinal pain (with a drop at follow-up of 55.44 points for the OID and 5.66 for the EVA); 78.3% of patients were very satisfied, 17.4% satisfied and 4.3% dissatisfied. Conclusion. The surgical treatment of Pott's disease and its sequelae greatly improved the spines at the Hospital Center of the Order of Malta.

ABSTRACT Objective: Tuberculosis (TB) represents one of the top ten causes of death in the world. Its insidious onset and nonspecific symptoms usually result in delayed diagnosis. The objective is to evaluate the characteristics of patients with tuberculous spondylodiscitis in follow-up at a South American reference hospital. Method: Retrospective evaluation of the medical records of patients of both sexes and between 0 and 80 years of age diagnosed with tuberculosis of the spine between 2009 and 2018. The variables were analyzed based on groups: epidemiological, clinical, laboratorial, microbiological, imaging tests and treatment. Results: Total of 26 cases, about 80.8% male, mean age 41.6 ± 22.46 years. Axial pain was the most prevalent symptom (84.6%), the VAS score was 6.85 ± 2.87. The mean time between symptom onset and diagnosis was 23.8 ± 24.1 weeks (4-96). The most affected region was the thoracic spine (50% of the cases). Most participants (61.4%) had no change in neurological function (Frankel D and E) at the beginning of treatment and after 6 months, and 84.5% improved. During treatment 34.6% required surgery and the main indication was isolated neurological deficit (55.5%). The most frequently performed procedure was decompression and arthrodesis (55.5%). The average time to cure was 12.0 ± 8.8 months (8-48). Conclusion: Disease with insidious onset, nonspecific symptoms, high frequency of negative microbiological tests in cases with the disease. A small number of the cases required surgical treatment and most of them achieved good neurological recovery. Level of evidence IV; Case series.

ABSTRACT Objective: To analyze the occurrence of notified cases of bone tuberculosis in Brazil during the period from 2009 to 2018. Methods: Quantitative, descriptive and retrospective study. The data consisted of cases reported to the Notifiable Diseases Information System (SINAN) of DATASUS. To analyze the results, the non-parametric statistical Chi-squared and G tests, capable of expressing statistical associations, were used. Results: 6,442 cases of bone tuberculosis were reported in Brazil, with an average of 644.2 cases per year. The Southeast was responsible for 41.5% of the cases (n = 2676). The extrapulmonary form accounted for 87.9% (5661). There was a predominance in males (66.1%, n = 4258), Whites (41.6%, n = 2678) and in the above 35 years of age group (73.9%, n = 4757). In the data collected, the risk factor data was not correctly filled out, making reliable statistical associations impossible in this study, mainly between alcoholism, tobacco use, AIDS, diabetes, mental illness, illicit drug use and homelessness. Conclusion: There was greater notification of cases of bone tuberculosis in the Southeast and Northeast regions of Brazil, which predominantly affected young, economically productive men. Tuberculosis has a correlation with diabetes, HIV / AIDS, smoking and alcohol and drug use, according to the results of this study. Level of evidence II; Retrospective, analytical, quantitative and descriptive study.

A preliminary study on the surgical timing of spinal tuberculosis / 中国骨伤

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.

Deformidad de Gibbus no tuberculosa tratada con implante cubierto con nanopartículas de plata. Presentación de un caso / Non-tuberculous gibbus deformity, treated with and implant coated with silver nanoparticles. Presentation of a case

Se conoce como enfermedad de Gibbus al colapso de la porción anterior de uno o más cuerpos vertebrales que provoca una cifosis segmentaria de ángulo agudo. En general, este tipo de deformidades son producto de infecciones tuberculosas. Uno de los principales problemas que trae apareado esta deformidad es la compresión medular. En el caso presentado, el paciente sufrió esta enfermedad como consecuencia de una infección no tuberculosa, con cifosis angular pososteomielitis, tratado con doble vía de abordaje, utilizando implantes recubiertos con nanopartículas de plata. Los resultados clínico-radiológicos fueron muy satisfactorios. Este caso presenta la conjugación de dos temas poco frecuentes en la medicina actual; por un lado, un tipo de deformidad de la columna que, rara vez, se debe a una infección no tuberculosa y, por otro lado, el implante utilizado, recubierto con nanopartículas de plata que, pese a las controversias, ofrece una nueva posibilidad de tratamiento para pacientes con un riesgo aumentado de infección asociada a implantes, y resulta de interés que sea reconocido por los cirujanos ortopedistas, puesto que existe evidencia suficiente para afirmar su capacidad para reducir la formación de biopelículas. Nivel de Evidencia: IV

Gibbus disease is the collapse of the anterior portion of one or more vertebral bodies that results in acute angle segmental kyphosis. Generally, these types of deformities are caused by tuberculosis infections. One of the main problems associated with this deformity is spinal compression. In this case, the patient presented this condition as a consequence of a non-tuberculous infection, with angular kyphosis after osteomyelitis, treated with a double approach, using implants coated with silver nanoparticles. We obtained very satisfactory clinical and radiological outcomes. This case presents the intersection of two rare topics in current medicine; on the one hand, a type of spinal deformity that rarely occurs as a consequence of a non-tuberculous infection. On the other hand, the implant used, coated with silver nanoparticles. Although there are still controversies in the literature, this implant offers a new possibility of treatment for patients who are at increased risk of implant-related infection, and it is of interest for orthopedic surgeons, since there is sufficient evidence to support its ability to reduce the formation of biofilms. Level of Evidence: IV

Minimally invasive direct lateral approach debridement, interbody bone grafting, and interbody fusion combined with posterior percutaneous pedicle screw fixation for lumbar spinal tuberculosis / 中国骨伤

OBJECTIVE@#To investigate the clinical efficacy and superiority of direct lateral interbody fusion combined with posterior percutaneous screw fixation in the treatment of lumbar tuberculosis.@*METHODS@#From June 2013 to August 2016, the clinical data of 83 patients with lumbar tuberculosis were retrospectively analyzed, including 55 males and 28 females, aged from 27 to 72 (49.5±13.5) years. These 83 patients were divided into two groups according to different operation methods, 35 cases in group A were treated with direct lateral interbody fusion combined with posterior percutaneous screw fixation;48 cases in group B were treated with anterior traditional extraperitoneal debridement combined with posterior internal fixation. After operation, regular quadruple antituberculosis drugs were continued for 18 months. The operation time, intraoperative blood loss, hospital stay, bone graft fusion time and complications were compared between the two groups. Visual analogue score (VAS) of lumbar pain, Oswestry Disability Index (ODI), sagittal Cobb angle, erythrocyte sedimentation rate (ESR) and C-reactive protein(CRP) values before and after operation were analyzed.@*RESULTS@#The operation was successfully completed in both groups, and the operation mode was not changed during operation. The operation time, intraoperative blood loss and hospital stay were (149.4±13.3) min, (354.3±69.0) ml, (9.4±1.6) d in group A and(116.8±10.0) min, (721.9±172.3) ml, (11.8±1.7) d in group B, respectively, with significant difference between the two groups (@*CONCLUSION@#The two kinds of operation can obtain satisfactory clinical effect. Direct lateral interbody fusion combined with posterior percutaneous screw fixation can reduce intraoperative blood loss and hospital stay, which is conducive to early rehabilitation of patients.

OBJECTIVE@#To compare the clinical effects of three different methods of binding multi-fold rib graft, iliac bone graft and titanium mesh graft in tuberculosis of thoracic vertebra by approach of transverse rib process.@*METHODS@#A hundred and seven patients with tuberculosis of thoracic vertebra received surgical treatment from January 2010 to December 2016 were retrospectively analyzed. The patients were divided into three groups according different methods of bone graft. The surgical approach of the transverse rib process was used in all 107 patients, after thoroughly remove the necrotic tissue of tuberculosis, three different bone grafts were used respectively including iliac bone graft (36 cases, group A), binding multi-fold rib graft (35 cases, group B), titanium mesh bone graft (36 cases, group C). Perioperative indexes, the time required for bone graft during operation, intraoperation blood loss, the loss rate of the anterior edge of the lesion, Cobb angle, postoperative bone graft fusion time, spinal nerve recovery and Oswestry Disability Index were compared among three groups.@*RESULTS@#All the patients were followed up for 13 to 24 months, and the operation time required for bone graft was (23.2±4.1) min in group A, (23.8± 4.4)min in group B, and (25.5±4.2) min in group C, with no statistically significant difference among three groups (@*CONCLUSION@#The approach of transverse rib process for debridement of lesions can effectively treat tuberculosis of thoracic vertebra by binding multi-fold rib graft, iliac bone graft and titanium mesh graft, but binding multi-fold rib graft can effectively avoid iliac bone donor complications, and is an effective alternative to iliac bone graft, which is worth popularizing.

Tuberculosis vertebral con afectación pleural: reporte de un caso / Spinal tuberculosis with pleural involvement: a case report

Resumen La tuberculosis extrapulmonar representa hasta el 25% de todos los casos de tuberculosis. Los órganos más frecuentemente afectados son los ganglios linfáticos y la pleura. Alrededor del 10-11% de casos de tuberculosis extrapulmonar tienen afectación osteoarticular y de ellos la mitad con compromiso vertebral. La infección es causada por la diseminación hematógena del bacilo desde un foco primario al hueso esponjoso de los cuerpos vertebrales torácicos o lumbares principalmente. El síntoma característico es el dolor crónico de la columna vertebral, generalmente en el sitio afectado, sin otros síntomas o signos concomitantes. La asociación de tuberculosis vertebral con afectación pleural sin un foco pulmonar establecido es infrecuente, se ha descrito en 2.5% de pacientes e intriga acerca de su fisiopatología. En Colombia, no se encontraron reportes similares. Se describe el caso de una paciente joven con historia de dolor lumbar crónico que debutó con síntomas respiratorios persistentes asociado a síntomas constitucionales; en quien se comprobó la infección por Mycobacterium tuberculosis en vértebras toracolumbares y pleura. Este caso evidencia una historia natural atípica de la enfermedad, en la cual el mecanismo fisiopatológico parece haber sido la diseminación directa por contigüidad, y resalta la importancia de la sospecha clínica para garantizar un diagnóstico y tratamiento oportuno.

Abstract Extrapulmonary tuberculosis represents up to 25% of all cases of tuberculosis. The most frequently affected organs are lymph nodes, pleura and bone. Around 10-11% of cases of extrapulmonary tuberculosis have osteoarticular involvement and a half of them present vertebral involvement. The infection is caused by hematogenous spread of the bacillus from a primary focus to the cancellous bone of the thoracic or lumbar vertebral bodies mainly. The characteristic symptom is the chronic pain in the spine, usually in the affected site, without other concomitant symptoms or signs. The association between vertebral tuberculosis and pleural involvement without an established pulmonary focus is infrequent, it has been described in 2.5% of patients, an intrigue about its pathophysiology. Similar cases in Colombia have not been reported. This article describes a case of a young patient with a history of chronic low back pain that debuts with persistent respiratory symptoms associated with constitutional symptoms; whose Mycobacterium tuberculosis infection was proven in thoracolumbar vertebrae and pleura. This case shows an atypical natural history of the disease, in which the pathophysiological mechanism of the disease would seem to have been the direct dissemination by contiguity, and emphasizes the importance of clinical suspicion to ensure timely diagnosis and treatment.

One-stage transpedicular debridement, posterior internal fixation and fusion for the treatment of senile thoracolumbar tuberculosis / 中国骨伤

OBJECTIVE@#To evaluate the clinical outcomes of one-stage transpedicular debridement, posterior internal fixation, RBK mixed streptomycin filled bone grafting for the treatment of elderly patients with thoracolumbar tuberculosis.@*METHODS@#The clinical data of 20 elderly patients with thoracolumbar tuberculosis underwent one stage transpedicular debridement, posterior internal fixation, OSTEOSET RBK mixed streptomycin-filled bone grafting from September 2006 to July 2017 were retrospectively analyzed. There were 12 males and 8 females, aged from 62 to 83 years with an average of (72.4±6.9) years old. Visual analogue scale (VAS), Oswestry Disability Index (ODI)were used to evaluate the pain and spinal function. The kyphosis angle (Cobb angle) of the lesion segment and the bone growth of the lesion area were observed by the X-ray films.@*RESULTS@#All the operations were successful, the operation time was (160.9±23.8) min, and the intraoperative blood loss was (317.9± 112.7) ml. The incisions were healed by first intention, and no sinus and incision were delayed. Spinal tuberculosis was completely cured, Frankel grade has one or more improvements. The VAS score decreased from (7.50±1.15) points before surgery to (1.70±1.39) points at 12 months after surgery (<0.05). The ODI score decreased from preoperative (92.50±1.17)% to (12.80±0.89)% at the final follow up (<0.05). The sagittal Cobb angle of the lesion segment decreased from preoperative (24.2±1.6)° to (8.3±0.7)°at 12 months after surgery(<0.05), the kyphosis deformity was significantly corrected. In all cases, bone fusion was achieved in bone graft area, without bone nonunion and device fracture complications.@*CONCLUSION@#One-stage transpedicular debridement, posterior internal fixation, RBK mixed streptomycin filled bone grafting is suitable for thoracolumbar tuberculosis patients with good general condition and less vertebral destruction.

Diagnosis and treatment of primary intraspinal abscess / 北京大学学报(医学版)

OBJECTIVE@#To summarize the feature and treatment of the primary intraspinal abscess in order to improve the prognosis.@*METHODS@#In the study, 13 cases of primary intraspinal abscess of the recent 20 years were retrospectively analyzed. The history, etiology, pathogen, surgical methods and prognosis were summarized.@*RESULTS@#The course of the illness ranged from 7 days to 6 months. All the cases began with pain. Of the 13 patients, 10 had limb weakness. Five had a fever and 8 had increased white blood cells. As for distribution, 1 was in cervical vertebra, 1 in cervicothoracic junction, 1 in thoracic vertebra, 4 in thoracolumbar junction, and 6 in lumbosacral segment. The results of bacterial culture were positive in 4 cases, 3 cases were diagnosed as tuberculosis by pathological examination, and 1 case was recognized as infection of Brucella melitensis bacteria because of prior brucellosis. The pathogen of the remaining cases were unclear. All the cases received surgical treatment and pathology examination. The surgical aim was mainly removal of the lesion, decompression and drainage. Postoperatively anti-infection and glucocorticoid therapy were performed according to the pathogeny results and clinical experience. Incision abscesses were seen in 2 cases and reoperations including debridement and repair with transferred muscle flap were performed. Postoperative follow-up ranged from 6 months to 3 years (mean 1.8 years). One case suffered postoperative recurrence and the abscess spread along the vertebral canal. Reoperation was performed. Infections of all the cases were recovered completely and the nervous system signs were all improved in different degrees.@*CONCLUSION@#The onset of primary intraspinal abscess is relatively urgent, mainly with pain. The lumbar and sacral vertebra is the predilection site. The bacterial culture is mostly negative. Early operation and use of sufficient amount of broad-spectrum antibiotic are recommended. If the incision abscess forms after the operation, it is advisable to transfer the muscle flap to repair the coloboma on the basis of debridement. In order to relieve edema of spinal cord and nerve root, the glucocorticoid can be used in the escort of antibiotics.

Four-rod Technique Stabilization after Pedicle Subtraction Osteotomy (PSO) for the Treatment of Thoracolumbar Hyperkyphosis Secondary to Pott Disease: A Two-Year Follow-Up Case Report

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.

A Case of Cervical Pott's Disease Presenting as Huge Retropharyngeal Abscess / 대한이비인후과학회지

Tuberculous spondylitis, also known as Pott's disease, is a disease involving the spine with progressive destruction. It most commonly involves the thoracic and lumbosacral spine and may result in severe deformity or neurologic deficit. Although cervical spine involvement is rare, it can cause life threatening event. Recently, 70-year-old man presented with progressive dyspnea and dysphagia. Physical examination and radiologic studies showed a huge retropharyngeal abscess with bony erosion and sclerotic change at the adjacent cervical spine. After incision and drainage, it was finally confirmed as a tuberculous abscess. Herein, we report our experience with literature review.

Extended Posterior Decompression and Instrumented Fusion for Spinal Tuberculosis

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.
