ABSTRACT
Objetivo: Apresentar as modalidades de tratamentos cirúrgicas mais usadas disponíveis no arsenal terapêutico das desordens temporomandibulares (DTMs). Revisão da literatura: As DTMs são muito frequentes e são responsáveis ââpor dor e desconforto em um número importante de pacientes. A avaliação e o diagnóstico são as chaves para determinar um plano de manejo adequado dessas doenças. Embora o tratamento conservador seja bem-sucedido na maioria dos pacientes, os tratamentos cirúrgicos podem ser a única opção para aqueles que não respondem ao tratamento conservador ou para casos com indicação cirúrgica inicial como, por exemplo, algumas neoplasias articulares. Dentre as alternativas cirúrgicas, podemos citar a artrocentese, artroscopia, reposicionamento do disco articular por cirurgia aberta, discectomia e tratamentos cirúrgicos para hipermobilidade e anquilose da articulação temporomandibular. Considerações finais: A seleção adequada dos casos é requisito obrigatório para uma intervenção cirúrgica bem-sucedida, a fim de alcançar o resultado desejado do tratamento, como alívio dos sintomas e melhora da função.
Aim: To present the most commonly used surgical treatment modalities available in the therapeutic arsenal for temporomandibular disorders (TMD). Literature review: TMD is very common and is responsible for pain and dysfunction in a significant number of patients. Assessment and diagnosis are key to determining a management plan for these diseases. Although conservative treatment is successful in most patients, surgical treatments may be the only option for those who do not respond to conservative treatment or for some cases with an initial surgical indication, such as some joint neoplasms. Surgical alternatives include arthrocentesis, arthroscopy, repositioning of the articular disc by open surgery, discectomy and surgical treatments for temporomandibular joint hypermobility and ankylosis. Conclusions: Proper case selection is the mandatory requirement for successful surgical intervention in order to achieve the desired treatment outcome, such as symptom relief and improved function.

OBJECTIVE@#To compare the clinical efficacy of full endoscopic lamina fenestration discectomy (Endo-LOVE) with full endoscopic transforaminal approach discectomy in the treatment of degenerative lumbar lateral recess stenosis.@*METHODS@#A retrospective analysis of 48 patients with degenerative lumbar lateral recess stenosis between March 2018 and March 2019 was performed. There were 32 males and 16 females, aged from 60 to 83 years old with an average of (72.9±6.5) years, course of disease ranged from 5 to 16 years with an average of (8.0±2.8) years. The patients were divided into observation group and control group according to surgical approaches. There were 28 cases in observation group, underwent Endo-LOVE surgery;and 20 cases in control group, underwent full endoscopic foraminal approach discectomy. The operation time, intraoperative blood loss, hospitalization day and complications were observed between two groups. Visual analgue scale (VAS), Japanese Orthopaedic Association(JOA), Oswestry Disability Index(ODI), lateral crypt angle were compared between two groups. And clinical effects were evaluated by modified Macnab standard.@*RESULTS@#There was no significant difference in follow-up and operation time between two groups (P>0.05). Intraoperative blood loss was from 5 to 15 ml with an average of (8.4±3.6) ml in observation group and 5 to 25 ml with an average of (11.5±5.4) ml in control group. The hospitalization day was from 5 to 8 days with an average of (6.0±1.0) days in observation group and 6 to 9 days with an average (7.2±1.1) days in control group. Intraoperative blood loss and hospitalization day were significantly lower in observation group(P<0.05). There were no serious complications in both groups. The VAS, JOA scores, and ODI at 3-month and final follow-up were significantly improved in both groups (P<0.05), and observation group was significantly better than control group (P<0.05). The skeletal lateral crypt angle and soft lateral crypt angle were significantly greater than the preoperative angle at 3 days postoperatively(P<0.05), and observation group was significantly better than control group(P<0.05). At the final follow-up, the modified Macnab criteria was used to assess clinical efficacy, in observation group, 22 patients obtained excellent results, 5 good and 1 fair;while 11 excellent, 4 good and 5 fair in control group;the clinical efficacy of observation group was significantly better than that of control group(P<0.05).@*CONCLUSION@#Both surgical methods are performed under direct vision, with high safety and good clinical efficacy. However, Endo-LOVE enlarged the lateral crypt more fully.

OBJECTIVE@#To compare the clinical efficacy between visual trephine arthroplasty assisted percutaneous transforaminal endoscopic discectomy (VPTED) and traditional percutaneous transforaminal endoscopic discectomy(PTED) in the treatment of lumbar disc herniation.@*METHODS@#The clinical data of 60 patients with lumbar disc herniation admitted from June 2019 to December, 2020 was retrospectively analyzed. There were 38 males and 22 females, aged from 26 to 58 years old with an average of (43.63±8.48) years, 47 cases were on L4,5 segment and 13 cases were on L5S1 segment. Among them, 32 were treated with VPTED (group A) and 28 were treated with traditional PTED (group B). The general conditions of all the patients were recorded, including intraoperative fluoroscopy times, operation time, hospital stay and surgical complications during follow-up. The arthroplasty area ratio was observed by sagittal CT at the middle level of the intervertebral foramen. Visual analogue scale (VAS) and Japanese Orthopaedic Association (JOA) score of low back pain, Oswestry disability index (ODI) were used to evaluate the clinical efficacy between two groups.@*RESULTS@#All patients were followed up from 9 to 15 months with an average of (12.10±1.16) months. There was no statistical difference of preoperative general data between two groups. The operation time, fluoroscopy times and hospital stay were (70.47±5.87) min, (13.66±1.34) times and (6.31±0.69) d in group A, and (90.71±7.66) min, (22.82±2.48) times and (6.54±0.92) d in group B. The operation time and intraoperative fluoroscopy times in group A were lower than those in group B(P<0.05). There was no significant difference in hospital stay between two groups (P>0.05). No obvious surgical complications were found during the follow-up in both groups. The arthroplasty area ratio in group A was (29.72±2.84)% and (29.57±2.20)% in group B, respectively, with no significant difference (P>0.05). There was no significant difference in VAS, ODI and JOA score between two groups before operation and at the final follow-up(P>0.05), but the final follow-up was significantly improved(P<0.05).@*CONCLUSION@#The two surgical methods have definite clinical efficacy in the treatment of lumbar disc herniation. Visual trephine arthroplasty assisted percutaneous transforaminal endoscopic discectomy has the advantages of high efficiency and rapidity when establishing the channel, and can significantly reduce the operation time and intraoperative fluoroscopy times.

OBJECTIVE@#To observe clinical efficacy of percutaneous endoscopic transforaminal discectomy (PETD) and target radioffrequency thermal coblation nucleoplasty(CN) on inclusive lumbar disc herniation(LDH) in different age groups, and provide a basis for clinical formulation of precise and individualized treatments.@*METHODS@#A retrospective analysis of 219 patients with lumbar disc herniation treated with PETD and CN between January 2018 and June 2021 was performed, in which 107 patients were treated with PETD and 112 with CN. Patients were stratified by age into young group(≤45 years old), middle-aged group(>45 years old and <60 years old) and older group(≥60 years old). Before treatment, 3 days, 1 month and 6 months after treatment, visual analogue scale (VAS), Japanese Orthopaedic Association (JOA) score, infrared thermal imaging temperature difference (△T) and lumbar range of motion (ROM) were evaluated and clinical efficacy were compared in the different age groups between two treatment methods.@*RESULTS@#①VAS and JOA score outcomes, in the same age group and the same treatment method, the VAS and JOA scores at different time points postoperatively were obviously improved (P<0.05). For the same age group and the different treatment methods, the older group had lower VAS and higher JOA scores after PETD than after CN (P<0.05), and there was no significant difference between the young group and middle-aged group (P>0.05). There was no significant difference in VAS and JOA scores at the same time between age groups by PETD treatment (P>0.05). The VAS was higher and the JOA score was lower in older group than in young group and middle-aged group at 1, 6 months after CN treatment(P<0.05). ②△T and ROM outcomes, in the same age group and same treatment method, postoperative △T and ROM at different time points were obviously improved(P<0.05). There was no significant difference in △T between two methods of PETD and CN at the same age(P>0.05), there was no significant difference in ROM between young group and middle-aged group(P>0.05), ROM was higher after PETD treatment than after CN treatment(P<0.05). There was no significant difference in △T and ROM at the same time between age groups by PETD treatment(P>0.05). There was no significant difference in △T between age groups by CN treatment, but the ROM was smaller in older group than in young group and middle-aged group after CN treatment(P<0.05).@*CONCLUSION@#Both PETD and CN for inclusive LDH have good efficacy, the curative benefit for older patients receiving PETD within 6 months after surgery more than CN, and CN is more appropriate for young and middle-aged patients.

Introduction and Importance Neurological deterioration due to buckling of the ligamentum flavum (LF) is an uncommon complication after anterior cervical corpectomy or discectomy with fusion. Case Presentation In this report, we present the case of a 66-year-old male who underwent anterior cervical partial corpectomy of C5 and discectomy of prolapsed C5- C6 with fusion. Postsurgery, the patient displayed signs of neurological deterioration. Upon immediate cervical magnetic resonance imaging (MRI), posterior canal stenosis and severe compression with cord signal due to LF buckling were detected. A posterior laminectomy procedure and canal decompression at the C5-C6 level with bone fusion were performed. Clinical Discussion Patient presented with walking difficulty, then walking disability, followed by bilateral upper and lower limb paresthesia with burning sensation. Examination showed â muscle strength in both handgrips. Further investigation showed brisk deep tendon reflexes, positive Hoffman sign unilaterally, equivocal Babinski sign, and progressive quadriparesis. Magnetic resonance imaging showed mild and diffuse building of some cervical discs, with spinal cord progression. We performed an anterior cervical corpectomy and fusion (ACCF) and anterior cervical discectomy and fusion (ACDF); a titanium mesh with plates and screws was used for fusion, with removal of a calcified and herniated subligamentous disc. Postoperatively, upper and lower limb strength deteriorated; immediate cervical and thoracic MRI showed LF buckling, which caused canal stenosis and severe compression. Urgent posterior laminectomy and canal decompression with bone fusion was scheduled on the same day. The patient underwent physiotherapy and regained upper and lower limb strength and his ability to walk. Conclusion This indicates the possibility of neurological deterioration as a result of LF buckling, whichmay be a result of LF thickening accompanied by hyperextension in the cervical region. In this regard, immediate imaging following signs of neurological complications after anterior cervical corpectomy or discectomy warrants early detection, which results in a better prognosis.

Abstract Prone position though is commonly used for better access to surgical site, but may be associated with a variety of complications. Perioperative Visual Disturbances or loss is rare but a devastating complication that is primarily associated with spine surgeries in prone position. In this case we report a 42 year old ASA-II patient who developed anisocoria with left pupillary dilatation following lumbar microdiscectomy in prone position. Following further evaluation of the patient, segmental pupillary palsy of the left pupillary muscles was found to be the possible cause of anisocoria. Anisocoria partially improved but persisted till follow up.
Resumo O posicionamento em decúbito ventral, embora comumente usado para melhorar o acesso ao local cirúrgico, pode estar associado a uma variedade de complicações. Distúrbios ou perda visual no Perioperatório é uma complicação rara, mas devastadora, que está principalmente associada à cirurgia de coluna vertebral em decúbito ventral. Relatamos aqui o caso de um paciente de 42 anos de idade, ASA - II, que desenvolveu anisocoria com dilatação pupilar esquerda após microdiscetomia lombar em decúbito ventral. Após uma avaliação adicional do paciente, observamos que a paralisia segmentar dos músculos pupilares esquerdos seria a possível causa de anisocoria. A anisocoria melhorou parcialmente, mas persistiu até o acompanhamento.

INTRODUCTION: Radiculopathy by lumbar disc herniation is a major cause of morbidity faced by spinal surgeons. There are many treatment strategies for this condition, and no current consensus among sequestrectomy and discectomy, and the need to merge the segment. OBJECTIVE: Show our results at 4 years of follow-up in the surgical treatment of lumbar disc herniation by foraminal discectomy. METHOD: A prospective study was conducted in patients diagnosed with lumbar disc herniation and foraminal surgically treated by simple discectomy and assessed four years later. RESULTS: The sample consisted of 67 patients, the majority (62.69%) was male; average age of nearly 40 years in both sexes. The diagnosis was confirmed in 85.3% of cases by MRI. L5-S1 and L4-L5 locations predominated, with 16% of more than one segment. Oswestry index and the Visual Analog Scale for pain showed significant improvement after four years of surgery. CONCLUSIONS: The surgical treatment of herniated discs by simple foraminal discectomy, in our experience, has good results; at four years of operation pain decrease and improvement in function was found
INTRODUCTION: La radiculopathie par hernie discale lombaire est la cause de morbidité la plus souvent traitée par les chirurgiens spécialisés en moelle épinière. Il y a plusieurs stratégies de traitement pour cette affection, mais aujourd'hui il n'y a pas de consensus ni entre la séquestrectomie et la discectomie ni sur la nécessité de fusionner le segment. OBJECTIF: Le but de ce travail est de montrer, après 4 ans de suivi, nos résultats à propos du traitement chirurgical d'une hernie discale lombaire par décompression foraminale. MÉTHODE: Une étude descriptive et prospective de patients diagnostiqués de hernie discale lombaire, traités chirurgicalement par décompression foraminale simple et évalués quatre ans après, a été réalisée. RÉSULTATS: Dans un échantillon de 67 patients, dont la plupart étaient du sexe masculin (62,69 %) et avaient un moyen d'âge de 40 ans environ chez tous les deux sexes, on a confirmé le diagnostic par IRM dans 85,3 % des cas. Les hernies ont été souvent localisées aux niveaux L5-S1 et L4-L5, dont 16 % correspondait à plus d'un segment. Quatre ans après l'opération, l'indice d'Oswestry et l'échelle visuelle analogique de douleur ont montré une amélioration significative. CONCLUSIONS: D'après notre expérience, le traitement chirurgical des hernies discales lombaires par décompression foraminale simple a montré de très bons résultats. Quatre ans après l'opération, on a constaté une diminution de la douleur et une amélioration de la fonction.

OBJECTIVES: Hydrodiscectomy is a new technique used for percutaneous spinal discectomy that employs a high-intensity stream of water for herniated disc ablation and tissue aspiration. No previous clinical study has examined the effects of percutaneous hydrodiscectomy. The aim of this study is to evaluate the outcomes of hydrodiscectomy compared to open microdiscectomy regarding pain, function, satisfaction, complications and recurrence rates. METHODS: In this randomized clinical trial, patients referred to our tertiary hospital for lumbar back pain were recruited and included in the study if they had disc protrusion or small herniation in only one level, without neurological deficits and with no resolution after six weeks of conservative treatment. One group underwent open microdiscectomy, and the other group underwent percutaneous microdiscectomy via hydrosurgery. Function was evaluated using the Oswestry Disability Index and pain was assessed using a visual analog scale. Evaluations were performed preoperatively, and then during the first week and at one, three, six and twelve months postoperatively. Personal satisfaction was verified. Clinicaltrials.gov: NCT01367860. RESULTS: During the study period, 20 patients were included in each arm and 39 completed one-year of follow-up (one patient died of unrelated causes). Both groups exhibited equal improvement on the visual analog scale and Oswestry evaluations after treatment, without any significant differences. The improvement in the lumbar visual analog scale score was not significant in the hydrodiscectomy group (p=0.138). The rates of infection, pain, recurrence and satisfaction were similar between the two groups. CONCLUSION: Percutaneous hydrodiscectomy was demonstrated to be as effective as open microdiscectomy for reducing pain. The rates of complications and recurrence of herniation were similar between groups. Patient satisfaction with the treatment was also similar between groups.

The major problems of revision surgery for recurrent lumbar disc herniation (LDH) include limited visualization due to adhesion of scar tissue, restricted handling of neural structures in insufficient visual field, and consequent higher risk of a dura tear and nerve root injury. Therefore, clear differentiation of neural structures from scar tissue and adhesiolysis performed while preserving stability of the remnant facet joint would lower the risk of complications and unnecessary fusion surgery. Biportal endoscopic spine surgery has several merits including sufficient magnification with panoramic view under very high illumination and free handling of instruments normally impossible in open spine surgery. It is supposed to be a highly recommendable alternative technique that is safer and less destructive than the other surgical options for recurrent LDH.

Antecedentes: El término de espondilolistesis degenerativa acuñado por Newman en 1963, es el deslizamiento hacia adelante de una vértebra inmediatamente inferior sin lisis ístmica. Se observa predominantemente en personas mayores de 40 años, con un predominio de 4:1 del sexo femenino, teniendo una prevalencia de 7.5% en hombres y 28% en mujeres, respectivamente en pacientes con lumbalgia mayores a 50 años. Material y métodos: Evaluar a un año el resultado del uso de espaciadores dinámicos en listesis grado 1 de Meyerding utilizando la escala de incapacidad de Oswestry. Se revisa el historial electrónico y radiográfico de los pacientes según los criterios en el período de Enero 2008 a Diciembre 2010 con el propósito de realizar un estudio de cohortes, retrospectivo, longitudinal y observacional. Resultados: El Oswestry prequirúrgico fue de 3.4% leve, 55.2% moderado y 41.4% severo; mientras que el postquirúrgico fue de 79.3% leve y 20.7% moderado. La cirugía más comúnmente realizada fue exploración y liberación con 72.4%, presentando discectomía únicamente en 27.6%. Los pacientes presentaron dolor irradiado a miembro pélvico derecho en 37.9%, miembro pélvico izquierdo en 44.8% y a ambos miembros pélvicos en 17.2%. Se presentó dolor postquirúrgico irradiado a miembro pélvico únicamente en 2.4%, siendo que en 100% de los casos presentaron algún tipo de dolor irradiado. Se utilizó espaciador DIAM en 79.3% y Wallis en 20.7%. Conclusiones: El tratamiento con espaciador interespinoso presenta un bajo índice de reintervención y, por lo menos a un año, presenta mejoría significativa en el índice de incapacidad.
Background: The term degenerative spondylolisthesis, coined by Newman in 1963, refers to the forward slippage of an immediately inferior vertebra without isthmic lysis. It occurs predominantly in individuals over 40 years of age and affects mainly women, with a female:male ratio of 4:1. Prevalence is 7.5% in males and 28% in females among patients over 50 years of age with low back pain. Material and methods: Assess the one-year results of the use of dynamic spacers for Meyerding grade 1 listhesis with the Oswestry disability scale. The patient's electronic and radiographic records from January 2008 to December 2010 were reviewed according to different criteria to conduct a retrospective, longitudinal and observational cohort study. Results: The preoperative Oswestry score was 3.4% mild, 55.2% moderate, and 42.4% severe; the postoperative score was 79.3% mild and 20.7% moderate. The most common surgical procedure was exploration and release in 72.4% of patients; only 27.6% underwent diskectomy. Pain irradiating to the right pelvic limb occurred in 37.9% of patients, to the left pelvic limb in 44.8%, and to both pelvic limbs in 17.2%. Only 2.4% of patients experienced postoperative pain that irradiated to the pelvic limb, as 100% of cases had some type of irradiating pain. A DIAM spacer was used in 79.3% and a Wallis device in 20.7%. Conclusions: Treatment with an interspinous spacer results in a low reoperation rate and, at least one year later, it resulted in a significant improvement in the disability rate.

Existen diversos programas e intervenciones para la rehabilitación de pacientes postoperados por hernia discal lumbar (HDL) sintomática. Para determinar el valor de las diferentes intervenciones de rehabilitación dentro del tratamiento postoperatorio de pacientes con HDL sintomática. Material y métodos: Revisión Sistemática. Búsqueda en bases de datos electrónicas desde Enero del 2000 hasta Octubre del 2012. Dos revisores independientes certificados para el uso de la escala PEDro evaluaron los ensayos clínicos incluidos en la revisión final; se incluyeron únicamente aquéllos con alta calidad metodológica; un tercer evaluador fungió de árbitro en caso de discrepancia entre los revisores. Hubo cegamiento de autores, instituciones y revistas para mejorar la precisión de calificaciones y validez interevaluador. Resultados: Se consideraron 15 ensayos clínicos para ser revisados por los evaluadores; 8 (53.3%) se consideraron de alta calidad metodológica (promedio 7.7 de 10 puntos). Se aleatorizaron 1099 participantes a diferentes grupos de tratamiento. No fue posible realizar un metaanálisis con los datos de los ensayos debido a las múltiples intervenciones y variables de desenlace utilizadas. Conclusiones: Se recomienda un programa de rehabilitación inmediata en pacientes postoperados por primera vez de microdisectomía. La intervención cognitiva con reforzamiento positivo aunado al ejercicio es un tratamiento eficaz; incluso se considera alternativo a la fusión vertebral en pacientes postoperados por HDL con recurrencia de síntomas posterior a una primera intervención. Los resultados de la actividad postquirúrgica temprana son generalmente excelentes y sin complicaciones. Se requiere aumentar el número y calidad metodológica de ensayos clínicos enfocados al tema para sustentar la utilidad de estas intervenciones en la práctica clínica diaria.
Various programs and interventions are available for the rehabilitation of patients who have undergone surgery for symptomatic lumbar disc herniation (LDH). Our aim is to determine the value of the different rehabilitation interventions included in the postoperative treatment of patients with symptomatic LDH. Material and methods: Systematic review. Search in electronic data bases from January 2000 to October 2012. Two independent reviewers certified in the use of the PEDro (Physiotherapy Evidence Data Base) scale assessed the clinical trials included in the final version; only those with high methodological quality were included. A third reviewer acted as arbitrator in case of discrepancy between reviewers. The reviewers were blinded to the authors, institutions and journals to increase the precision of their ratings and the inter-reviewer validity. Results: Fifteen clinical trials were reviewed by the reviewers; 8 (53.3%) were considered as having a high methodological quality (average of 7.7/10). Were randomized 1099 participants to different treatment groups. It was not possible to conduct a meta-analysis with the clinical trial data due to the multiple interventions and outcome measures used. Conclusions: An immediate rehabilitation program is recommended in patients undergoing micro-diskectomy for the first time. Cognitive intervention with positive reinforcement together with exercise is an effective treatment. It is even considered as an alternative to vertebral fusion in patients who underwent LDH surgery with symptom recurrence after the first surgery. The results of early postoperative activity are usually excellent and involve no complications. The number and the methodological quality of the clinical trials on this topic need to be increased to justify the usefulness of these interventions in the daily clinical practice.

Se mostró la terapéutica médica y quirúrgica ante un caso con osteomielitis vertebral secundaria a discectomía, mediante el estudio observacional descriptivo en un paciente de 50 años de edad, afecto de hernia discal del 5to. espacio lumbar, a quien se le había practicado discectomía abierta; que ingresó a los 15 días con un cuadro doloroso lumbar e hipertermia de 39 °C.Se hizo una revisión actualizada del tema de osteomielitis vertebral y se expuso la terapéutica quirúrgica y antimicrobiana realizada al paciente. Luego de desbridamientos quirúrgicos seriados demandantes y secuenciales, así como de irrigación continua, se observó la resolución del cuadro infeccioso y del cuadro radicular que presentaba el paciente. En consulta externa se reflejó la negatividad de las investigaciones analíticas de infección a los 4 meses de evolución. Se concluyó que es importante ante los signos clínicos de infección (dolor, fiebre), realizar una tomografía axial computarizada en un paciente con discectomía abierta, para ver la repercusión ósea y operar lo antes posible. La modalidad de desbridamiento secuencial y demandante con una irrigación continua de solución salina fisiológica 0,9 por ciento con antibiótico sensible al microorganismo, da resultados satisfactorios(AU)
Surgical and medical therapy was shown in a case of vertebral osteomyelitis secondary to disectomy by means of a descriptive observational study conducted in a 50 years old patient affected by herniation of the fifth lumbar disk that had undergone open disectomy; who was admitted 15 days after this with a painful lumbar manifestation and hyperthermia of 39 °C. An updated review of the topic of vertebral osteomyelitis was made and the surgical and antimicrobial therapy followed in the patient was shown. After demanding sequential serial surgical debridements with continuous irrigation, the resolution of the infectious and radicular manifestation that the patient presented was observed. The negative impacts of the analytical investigations of infection were presented in the outpatient consultation after four months of evolution. It was concluded that, in the presence of clinical signs of infection such as pain and fever, it is important to indicate a CT-scan to a patient who had undergone open disectomy to observe the osseous percussion and operate on as soon as possible. The modality of demanding sequential serial surgical debridement with continuous irrigation with 0.9 percent physiological saline solution and a sensitive antibiotic to the microorganism gives satisfactory results(AU)
Une étude observationnelle descriptive d'un patient âgé de 50 ans, atteint de hernie discale du 5e espace lombaire et d'ostéomyélite vertébrale, après discectomie ouverte, a permis de montrer la thérapeutique médicale et chirurgicale à suivre dans ces cas. Ce patient avait été hospitalisé 15 jours auparavant avec un tableau douloureux lombaire et une hyperthermie de 39 °C. Après avoir fait une révision actualisée du sujet de l'ostéomyélite vertébrale, une thérapeutique chirurgicale et antimicrobienne a été proposée. Des débridements chirurgicaux sériés et séquentiels, ainsi qu'irrigation continue, ont assuré la résolution de l'infection et du syndrome radiculaire affectant le patient. En consultation externe, les examens ont été négatifs d'infection en 4 mois. On a conclu qu'il est important d'effectuer une tomographie axiale informatisée chez un patient traité par discectomie ouverte avec des signes cliniques d'infection tels que douleur et fièvre, afin de déceler des séquelles osseuses et d'opérer le plus rapide que possible. La technique de débridement séquentiel, avec irrigation continue par solution saline physiologique à 0,9 pourcent et antibiothérapie sensible au micro-organisme, a des résultats satisfaisants(AU)
