ABSTRACT

OBJECTIVE@#To evaluate the value of high-resolution ultrasound the diagnosis and prognosis of cubital tunnel syndrome.@*METHODS@#From January 2018 to June 2019, 47 patients with cubital tunnel syndrome were treated with ulnar nerve release and anterior subcutaneous transposition. There were 41 males and 6 females, aged from 27 to 73 years old. There were 31 cases on the right, 15 cases on the left, and 1 case on both sides. The diameter of ulnar nerve was measured by high-resolution ultrasound pre-and post-operatively, and measured directly during the operation. The recovery status of the patients was evaluated by the trial standard of ulnar nerve function assessment, and the satisfaction of the patients was assessed.@*RESULTS@#All the 47 cases were followed up for an average of 12 months and the incisions healed well. The diameter of ulnar nerve at the compression level was (0.16±0.04) cm pre-operatively, and the diameter of ulnar nerve was (0.23±0.04) cm post-operatively. The evaluation of ulnar nerve function:excellent in 16 cases, good in 18 cases and fair in 13 cases. Twelve months post-operatively, 28 patients were satisfied, 10 patients were general and 9 patients were dissatisfied.@*CONCLUSION@#The preoperative examination of ulnar nerve by high-resolution ultrasound is consistent with the intuitive measurement during operation, and the result of postoperative examination of ulnar nerve by high-resolution ultrasound is consistent with follow-up results. High-resolution ultrasound is an effective auxiliary method for the diagnosis and treatment of cubital tunnel syndrome.

ABSTRACT

Selective dorsal neurotomy (SDN) is a surgical treatment for primary premature ejaculation (PE), but there is still no standard surgical procedure for selecting the branches of the dorsal penile nerves to be removed. We performed this study to explore the value of intraoperative neurophysiological monitoring (IONM) of the penile sensory-evoked potential (PSEP) for standard surgical procedures in SDN. One hundred and twenty primary PE patients undergoing SDN were selected as the PE group and 120 non-PE patients were selected as the normal group. The PSEP was monitored and compared between the two groups under both natural and general anesthesia (GA) states. In addition, patients in the PE group were randomly divided into the IONM group and the non-IONM group. During SDN surgery, PSEP parameters of the IONM group were recorded and analyzed. The differences in PE-related outcome measurements between the perioperative period and 3 months' postoperation were compared for the PE patients, and the differences in effectiveness and complications between the IONM group and the non-IONM group were compared. The results showed that the average latency of the PSEP in the PE group was shorter than that in the normal group under both natural and GA states (P < 0.001). Three months after surgery, the significant effective rates in the IONM and non-IONM groups were 63.6% and 34.0%, respectively (P < 0.01), and the difference in complications between the two groups was significant (P < 0.05). IONM might be useful in improving the short-term therapeutic effectiveness and reducing the complications of SDN.

ABSTRACT

Neurosurgery is a highly specialized field: it often involves surgical manipulation of noble structures and cerebral retraction is frequently necessary to reach deep-seated brain lesions. There are still no reliable methods preventing possible retraction complications. The objective of this study was to design work chambers well suited for transcranial endoscopic surgery while providing safe retraction of the surrounding brain tissue. The chamber is designed to be inserted close to the intracranial point of interest; once it is best placed it can be opened. This should guarantee an appreciable workspace similar to that of current neurosurgical procedures. The experimental aspect of this study involved the use of a force sensor to evaluate the pressures exerted on the brain tissue during the retraction phase. Following pterional craniotomy, pressure measurements were made during retraction with the use of a conventional metal spatula with different inclinations. Note that, although the force values necessary for retraction and exerted on the spatula by the neurosurgeon are the same, the local pressure exerted on the parenchyma at the edge of the spatula at different inclinations varied greatly. A new method of cerebral retraction using a chamber retractor (CR) has been designed to avoid any type of complication due to spatula edge overpressures and to maintain acceptable pressure values exerted on the parenchyma.

ABSTRACT

Alcohol abuse has impacts on public health worldwide. Conservative treatment to achieve abstinence consists of detoxification combined with psychotherapy and the use of drugs, but it is estimated that only half of the individuals achieve long-term abstinence with the available treatments. In this sense, neurosurgery appears as a therapeutic proposal. The present study aimed to gather information about the circuitry related to alcohol use disorder (AUD), to describe possible surgical targets, and to establish whether a surgical approach could be a safe and effective treatment option. A systematic review of the literature was conducted and reported according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. The 14 selected articles analyze ablative operations, deep brain stimulation (DBS), and a new procedure in which the patient is first submitted to repetitive transcranial magnetic stimulation to evaluate their response, and later an implant is surgically positioned on the evaluated target to obtain more lasting results. The most relevant outcomes were found when the anterior cingulate cortex (ACC) and the nucleus accumbens (NAcc) were used as targets, demonstrating a large reduction in alcohol intake and even its cessation. However, important side effects were observed, such as psychotic symptoms, right frontal venous infarction, seizures after implantation in the ACC and a hypomanic period after DBS in the NAcc, which could be reversed. Due to the lack of studies involving the surgical treatment of AUD, more clinical trials are needed to compare targets, to assess surgical techniques, and to estimate the safety of these techniques.

ABSTRACT

La craneotomía con paciente despierto (CPD) demanda un manejo multidisciplinario particular debido al componente de conciencia transoperatoria que aporta beneficios en la resección tumoral y preservación neurológica, pero también implica el manejo de los riesgos asociados a la necesidad de cooperación del paciente durante el procedimiento. En este trabajo se describen los beneficios y las complicaciones en pacientes operados bajo la modalidad de CPD. Además, se abordan los retos documentados tanto para el equipo profesional a cargo, como para los pacientes, los cuales tienen un rol activo durante la cirugía. En ese sentido, se exponen los criterios para la selección, preparación psicológica y neuropsicológica tanto previo como durante la cirugía. A su vez, se proponen las consideraciones para lograr un procedimiento exitoso y evitar las posibles secuelas psicológicas a largo plazo, como insumos para la protocolización de este tipo de procedimientos con base en nuestra experiencia.


Awake craniotomy (AC) requires a multidisciplinary management due to trans operative awareness, which benefits the tumor resection and neurologic preservation, but it also implies risks for the patient cooperation during the procedure. This article describes the benefits and complications in patients operated under AC. Besides, it approaches the documented challenges for both the professional team and patients, who have an active role during surgery. In this regard, the criteria for selection and psychological and neuropsychological preparation before and during surgery are set out. It suggests considerations to achieve a successful procedure and to avoid possible long- term psychological sequelae, as a resource for the protocol of this type of procedures based on our experience.

ABSTRACT

The COVID-19 pandemic has affected a large number of patients in all countries, overwhelming healthcare systems worldwide. In this scenario, surgical procedures became restricted, causing unacceptable delays in the treatment of certain pathologies, such as glioblastoma. Regarding this tumor with high morbidity and mortality, early surgical treatment is essential to increase the survival and quality of life of these patients. Association between COVID-19 and neurosurgical procedures is quite scarce in the literature, with a few reported cases. In the present study, we present a rare case of a patient undergoing surgical resection of glioblastoma with COVID-19.

ABSTRACT

Objective The purpose of the present study is to demonstrate the usefulness of intraoperative ultrasound guidance as a technique for the assessment, in real time, of tumor resection and as a navigation aid during intra-axial brain lesion removal on patients admitted in the Neurosurgical Department at the Hospital Universitario de Caracas, Caracas, Venezuela, in 2018. Methods A total of 10 patients were enrolled, each with intra-axial brain lesions with no previous neurosurgical procedures and a mean age of 49 years old, ranging from 29 to 59 years old. Results A male predominance was observed with 7 cases (70%) over 3 female cases (30%). Six patients had lesions in the dominant hemisphere. The frontal lobe was the most commonly affected,with 5 cases, followed by the parietal lobe,with 4 cases. After craniotomy, ultrasound evaluation was performed previously to dural opening, during tumor resection and after tumor removal. The mean tumor size in axial, coronal and sagittal views was 3.72 cm, 3.08 cm and 3.00 cm, respectively, previously to dural opening with intraoperative ultrasound. The average tumor depth was 1.73 cm from the cerebral cortex. The location and removal duration from the beginning of the approach (ultrasound usage time) was 83.60 minutes, and the average surgery duration was 201 minutes. Navigation with intraoperative ultrasound served to resect intra-axial tumors more precisely and safely. There was no postoperative complication associated with the surgery in this series of cases. Conclusions Intraoperative ultrasound guidance for intra-axial subcortical tumor resection is a technique that serves as a surgical and anatomical orientation tool.

ABSTRACT

Total intravenous anesthesia (TIVA) with propofol/remifentanil appears in the literatura as a good option for neurosurgical patients who have increased intracranial pressure (ICP),risk of postoperative nausea and vomiting (PONV), need for neuromonitoring, and in those with impaired brain self-regulation. On the other hand, in patients with normal neurological status, normal ICP, a technique with volatile (halogenated) agents plus an opiiid can be used. This review describes two anesthetic techniques available for use in neurosurgery, highlighting the neurophysiological changes, advantages and disadvantages of each technique. MATERIAL AND METHOD: PubMed search engine was used for bibliographic search. DISCUSSION: The search for an ideal anesthetic in neurosurgery is still a matter of debate. There are numerous investigations aimed at finding an optimal agent that ensure the coupling between cerebral flow (CBF) and metabolism, keeping self-regulation intact without increasing the CBF and intracerebral pressure (ICP). CONCLUSIONS: Both anesthetic techniques, TIVA and volatile agents (halogenated), can be used in neurosurgical procedures and should provide neuroprotection, brain relaxation and a rapid awakening.


La anestesia total endovenosa (TIVA) con propofol/remifentanilo aparece en la literatura como una buena opción para pacientes neuroquirúrgicos que tienen aumento de la presión intracraneana (PIC), riesgo de náuseas y vómitos posoperatorios (NVPO), necesidad de neuromonitoreo, y en aquellos con alteración de la autorregulación cerebral. Por otra parte, en pacientes con estado neurológico normal, PIC normal puede usarse una técnica con agentes volátiles (halogenados) más un opioide. Esta revisión describe dos técnicas anestésicas disponibles para su uso en neurocirugía, destaca los cambios neurofisiológicos, ventajas y desventajas de cada técnica. MATERIAL Y MÉTODO: Para búsqueda bibliográfica se usó buscador PubMed. DISCUSIÓN: La búsqueda de un anestésico ideal en neurocirugía sigue siendo tema de debate. Existen numerosas investigaciones destinadas a buscar un agente óptimo que asegure el acoplamiento entre flujo sanguíneo cerebral (FSC) y metabolismo, manteniendo la autorregulación intacta sin aumentar el FSC y presión intracerebral (PIC). CONCLUSIONES: Ambas técnicas anestésicas, TIVA y agentes volátiles (halogenados), pueden ser usadas en procedimientos neuroquirúrgicos y deben brindar neuroprotección, relajación cerebral y un despertar rápido.

ABSTRACT

Deep brain stimulation has become an option for advanced Parkinson's disease treatment since the 1990s, but the first reports are from Benabid's team, a French neurosurgeon, in the 1980s. The subthalamic nucleus (STN), more specifically its dorsolateral portion, is the most commonly stimulated brain area. One of the major aspects for a good surgical result is the accurate location of this target. Therefore, the present article aimed to identify landmarks that facilitate and refine the location of the STN using nuclear magnetic resonance imaging (NMRI) of the skull. In order to achieve this goal, a search for articles was performed using the PubMed and Science Direct online databases, and articles regarding the use of NMRI to target STN were included. The precise location of the dorsolateral portion of the STN is fundamental to achieve the best possible effect on motor symptoms and to minimize side effects. One of the most used location methods is the NMRI, associated or not with tomography or ventriculography. The location strategies can be classified as direct and indirect. Landmarks are among the indirect strategies, and the most important ones (red nucleus, Sukeroku sign, dent internal capsule sign, supramammillary commissure, mammillothalamic tract, and interpeduncular cistern) are described in the present article. The various landmarks can be combined to locate with more accuracy the dorsolateral portion of the STN and the ideal position of the electrodes to achieve the best possible clinical result.

ABSTRACT

Encephalocele is a protrusion of the central nervous system elements through a defect in the dura mater and in the cranium. The prevalence of encephalocele ranges from 0.08 to 0.5 per 1,000 births. The posterior encephaloceles are more common in North America and Europe, while frontal defect is frequently found in Asia. The present paper describes a 26-year-old male patient presenting with cerebrospinal fluid leak and meningitis symptoms. He was diagnosed with congenital nasoethmoidal encephalocele and treated surgically using a supraorbital approach without complications.

ABSTRACT

Background. Spina bifida (SB) is a neural tube defect (NTD) that has an increased risk of fatal and disabling effects if not repaired early, i.e. within the first 24 to 48 hours of life. Its diagnosis holds an increased burden for the patient and the caregiver owing to secondary complications. The effects of the disease are detrimental even with early repair, because of the long-term disabling nature of the disease.Objective. This retrospective study aimed to assess the effects of demographics, immediate post-surgical complications and impact of time to surgical intervention on the outcome of neonates with open SB (OSB) admitted to the neonatal intensive care unit (NICU) at Inkosi Albert Luthuli Central Hospital (IALCH) in KwaZulu-Natal, South Africa (SA), between January 2011 and December 2015.Methods. A retrospective chart review was conducted at the NICU of IALCH. All neonates diagnosed with SB were identified. The study period was from 1 January 2011 to 31 December 2015. Data were collected from the IALCH electronic database. All neonates with SB admitted to the IALCH NICU were included; any patient who presented beyond the neonatal period (i.e. >28 days) was excluded from the study. Data collected included maternal demographics. Additionally, neonatal history was reviewed and post surgery complications evaluated. Outpatient management post discharge was reviewed.Results. One hundred and fifty neonates were included (58% male). The mean (standard deviation) maternal age was 26.7 (6.6) years. Only 10% had an antenatal diagnosis of OSB. Seventy-eight percent were born at term and 22% prematurely. The lumbar/sacral region was the most commonly affected. More males (14%) had thoraco/lumbar lesions than females (7.8%). Forty-eight percent presented before 3 days of life (early presentation). In the late-presentation group, there was an association with wound sepsis (p=0.003). Twenty-five percent were repaired between days 0 and 3 of life and 75% after 3 days. Postoperative complications in patients whose open SBs were repaired beyond 3 days of life were not statistically significant compared with those with early repair; all were p>0.05. There was a borderline association of prolonged hospitalisation with wound sepsis (p=0.07). Long-term outcomes showed that 68% had lower limb dysfunction, 18% urological complications, 14% limb deformity, and 11% hydrocephalus. A minority had psychomotor (7%) and developmental (15%) disorders. Ten percent required readmission secondary to shunt complications, and 7% died. Conclusion. SB remains a significant disease burden that affects outcome and survival of neonates in SA. Lack of good antenatal care, which includes early ultrasound and timely referral to centres, are barriers to good outcomes. Long-term follow-up is also necessary to prevent morbidity

ABSTRACT

La reconstrucción de nervios periféricos con aloinjertos nerviosos acelulares humanos en neurocirugía ha sido bastante estudiada estableciendo su predictibilidad y éxito en intervenciones principalmente en los nervios digitales de las manos. En cirugía maxilofacial existe una creciente investigación para poder restaurar el nervio alveolar inferior en cirugías de resección mandibular en donde la extirpación de esta estructura nerviosa es inevitable. El objetivo de esta publicación es mostrar un reporte de un caso en donde se realizó la reconstrucción del nervio alveolar inferior con aloinjerto de nervio acelular humano (Avance® Nerve Graft, Axogen) con microcirugía para poder proveer de sensibilidad a la región de la cara afectada en un paciente reconstruido con un injerto de fíbula microvascularizada posterior a una hemimandibulectomía por ameloblastoma plexiforme.


The reconstruction of peripheral nerves with allografts of human acellular nerves in neurosurgery is well studied, establishing its predictability and success in interventions mainly in the digital nerves of the hands. In maxillofacial surgery there is a growing investigation to be able to restore the inferior alveolar nerve in mandibular resection surgeries where the removal of this nervous structure is inevitable. The objective of this publication is to show a case report in which the reconstruction of the inferior alveolar nerve was performed with human acellular nerve allograft (Avance® Nerve Graft, Axogen) with microsurgery in order to provide sensitivity to the region of the affected face in a reconstructed patient with a microvascularized bone fibula graft after hemimandibulectomy due to plexiform ameloblastoma.

ABSTRACT

Resumen La migraña afecta a un porcentaje importante de la población y los síntomas pueden interferir con calidad de vida de manera importante. A pesar de los avances en el manejo médico, existe una proporción de pacientes que no responden adecuadamente a la intervención farmacológica. En los últimos años, se han planteado nuevos enfoques en el tratamiento de la migraña. Éstos se basan en la teoría que ramas sensoriales extracraneales del trigémino y de los nervios espinales cervicales pueden irritarse, atraparse o comprimirse en algún punto a lo largo de su trayecto, generándose una cascada de eventos fisiológicos que finalmente resulta en la migraña. Se ha demostrado que la inyección diagnóstica y terapéutica de toxina botulínica y la descompresión quirúrgica de estos puntos gatillos reducen o eliminan las migrañas en pacientes que no responden adecuadamente a la intervención farmacológica y siguen sintomáticos. La evidencia que respalda la eficacia y seguridad de la descompresión quirúrgica de los puntos de gatillos periféricos se está acumulando rápidamente, y la tasa de éxito general de la cirugía se acerca a 90%. Este trabajo revisa la evidencia clínica y pretende proporcionar un artículo sobre el estado actual de la técnica en el tratamiento quirúrgico de las migrañas.


Migraine headaches affect a significant percentage of the population and the symptoms can interfere with quality of life in an important way. Despite advances in medical management, there is a proportion of patients who do not respond adequately to the pharmacological intervention. In recent years, new approaches have been proposed in the treatment of migraine. These are based on the theory that extracranial sensory branches of the trigeminal and cervical spinal nerves can become irritated, trapped or compressed at some point along their path, generating a cascade of physiological events that ultimately results in migraine. It has been shown that the diagnostic and therapeutic injection of botulinum toxin and the surgical decompression of these trigger points reduce or eliminate migraines in patients who do not respond adequately to the pharmacological intervention and remain symptomatic. The evidence supporting the efficacy and safety of surgical decompression of peripheral trigger points is rapidly accumulating, and the overall success rate of surgery approaches 90%. This paper reviews the clinical evidence and aims to provide an article on the current state of the art in the surgical treatment of migraines.

ABSTRACT

SUMMARY OBJECT: To explore the treatment effect of the anterior medial neurovascular interval approach to coronal shear fractures of the distal humerus. METHODS: This prospective study included two female patients who were 30-64 years old, with a mean age of 47 years. Fractures were caused by falling from a bicycle. The time between the injury and operation was 1-2 days, with a mean time interval of 1.5 days. Two patients with coronal shear fracture of the distal humerus were treated with open reduction and internal fixation using anterior neurovascular interval approach. RESULTS: There were no intraoperative and postoperative neurological and vascular complications or infections, and the fracture was united. At 12 months after the surgery, the patient returned to work without pain, and with a normal range of motion for elbow and forearm rotation. The X-rays revealed excellent fracture union, no signs of heterotopic ossification, and no traumatic arthritis. According to Mayo's evaluation standards for elbow function, a score of 100 is excellent. CONCLUSIONS: The application of the anterior neurovascular interval approach of the elbow in the treatment of shear fracture of the articular surface of the distal humerus, particularly the trochlea of the humerus, can reduce the stripping of the soft tissue.


RESUMO OBJETIVO: Explorar o efeito do tratamento com uma abordagem anterior do intervalo neurovascular médio para fraturas de cisalhamento coronal da porção distal do úmero. METODOLOGIA: Este estudo prospectivo incluiu duas pacientes do sexo feminino de 30-64 anos de idade, com idade média de 47 anos. As fraturas foram causadas por quedas de bicicleta. O tempo entre a lesão e a operação foi de 1-2 dias, com um intervalo de tempo médio de 1,5 dias. Duas pacientes com cisalhamento coronal da porção distal do úmero foram tratadas com redução aberta e fixação interna utilizando a abordagem anterior do intervalo neurovascular. RESULTADOS: Não houve complicações neurológicas e vasculares intra e pós-operatórias, nem complicações ou infecções, e a fratura foi unida. Após 12 meses da cirurgia, as pacientes retornaram ao trabalho sem dor e com uma amplitude normal de movimento de rotação do antebraço e cotovelo. Os raios-X revelaram excelente união das fraturas, sem sinais de ossificação heterotópica e sem artrite traumática. De acordo com as diretrizes da clínica Mayo para avaliação da função do cotovelo, uma pontuação de 100 é considerada excelente. CONCLUSÃO: A aplicação da abordagem anterior do intervalo neurovascular do cotovelo no tratamento de uma fratura de cisalhamento da superfície articular da porção distal do úmero, especificamente da tróclea do úmero, pode reduzir o desgaste do tecido mole.

ABSTRACT

ABSTRACT Objevect: To evaluate the Nutritional Status (NS) and follow the Enteral Nutritional Therapy (ENT) of patients in neurosurgical intervention. Method: Cohort study in emergency or elective surgery patients with exclusive ENT. Anthropometric measurements (Arm Circumference (AC and Triceps Skinfold (TSF)) were measured on the first, seventh and 14th day. For the ENT monitoring, caloric/protein adequacy, fasting, inadvertent output of the enteral probe and residual gastric volume were used. Results: 80 patients, 78.7% in emergency surgery and 21.3% in elective surgery. There was a reduction in AC and Body Mass Index (BMI) (p>0.01), especially for the emergency group. The caloric/protein adequacy was higher in the emergency group (86.7% and 81.8%). Conclusion: The EN change was greater in the emergency group, even with better ENT adequacy. Changes in body composition are frequent in neurosurgical patients, regardless of the type of procedure.


RESUMEN Objetivo: Evaluar el Estado Nutricional (EN) y acompañar la Terapia Nutricional Enteral (TNE) de pacientes en intervención neuroquirúrgica. Método: Estudio tipo cohorte en pacientes de cirugía de urgencia o electiva, con TNE exclusiva. Se midieron medidas antropométricas (Circunferencia del Brazo (CB) y Pliegue Cutáneo Tricipital (PCT)) en el primer, séptimo y decimocuarto días. Para el monitoreo de la TNE: adecuación calórica/proteica, desayuno, salida inadvertida de la sonda enteral y volumen residual gástrico. Resultados: 80 pacientes, 78,7% en cirugía de urgencia y 21,3% en electiva. Hubo reducción de la CB y del Índice Masa Corporal (IMC) (p> 0,01), en especial para el grupo de urgencia. La adecuación calórica/proteica fue superior en el grupo de urgencia (86,7% y 81,8%). Conclusión: La alteración del EN fue más alta en el grupo de urgencia mismo con mejor adecuación de la TNE. La alteración de la composición corporal es frecuente en pacientes neuroquirúrgicos independientemente del tipo de procedimiento.


RESUMO Objetivo: Avaliar o Estado Nutricional (EN) e acompanhar a Terapia Nutricional Enteral (TNE) de pacientes em intervenção neurocirúrgica. Método: Estudo tipo coorte em pacientes de cirurgia de urgência ou eletiva, com TNE exclusiva. Foram aferidas medidas antropométricas (Circunferência do Braço (CB) e Dobra Cutânea Tricipital (DCT)) no primeiro, sétimo e 14º dia. Para o monitoramento da TNE, utilizou-se: adequação calórico/proteica, jejum, saída inadvertida da sonda enteral e volume residual gástrico. Resultados: 80 pacientes, 78,7% em cirurgia de urgência e 21,3% em eletiva. Houve redução da CB e do Índice de Massa Corporal (IMC) (p>0,01), em especial para o grupo de urgência. A adequação calórica/proteica foi superior no grupo de urgência (86,7% e 81,8%). Conclusão: A alteração do EN foi maior no grupo de urgência mesmo com melhor adequação da TNE. A alteração da composição corporal é frequente em pacientes neurocirúrgicos, independentemente do tipo de procedimento.

ABSTRACT

Objectif: Présenter et discuter les résultats de l'activité neurochirurgicale au Centre Hospitalier Régional Lomé Commune.Patients et Méthode:Nous avons mené une étude rétrospective de Juillet 2014 à Juillet 2016, incluant les patients opérés pour une affection neurochirurgicale. Les paramètres étudiés étaient épidémio- logiques, diagnostiques, chirurgicaux et évolutifs. Résultats:Cent quatre-vingt-douze patients ont été opérés. Leur âge moyen était de 42,14 ans [0-72]. Le sex ratio étaitde 1,94 en faveur des hommes. La durée moyenne du séjour hospitalier en post opératoire était de 8,2 jours. Les affections dégénératives du rachis ont été la première pathologie concernée par la chirurgie (49,48%), suivies des traumatismes du rachis (17,19%). L'évolution a été favorable dans 90,1% des cas, pour l'ensemble de la série. Nous avons noté 1,6% de cas d'infection du site opératoire, sur l'ensemble de la série. Conclusion : Les résultats sont encourageants pour l'ensemble de la série. L'essor de la pratique neurochirurgicale au Togo nécessite la création d'unités neurochirurgicales indépendantes, une amélioration du plateau technique et une coopération multidisciplinaire

ABSTRACT

SUMMARY OBJECTIVE: The surgical management of high-grade lumbar spondylolisthesis (HGLS) is complex and aims to achieve both a solid fusion that is able to support the high shear forces of the lumbosacral junction, as well as neural decompression. We performed a systematic literature review of the safety and efficacy of posterior transdiscal (PTD) screw fixation from L5S1 for HGLS and its variations. METHODS: A systematic literature review following the PRISMA guidelines was performed in the PubMed database of the studies describing the use of PTD screw fixation for HGLS. Clinical and radiological data were extracted and discussed. Study quality was assessed with the Oxford Centre for Evidence-Based Medicine Levels of Evidence. RESULTS: Seven studies were included and reviewed; all of them were level IV of evidence. Two of them had large case series comparing different surgical techniques: one concluded that PTD was associated with better clinical outcomes when compared with standard screw fixation techniques and the other suggesting that the clinical and radiological outcomes of PTD were similar to those when an interbody fusion (TLIF) technique was performed, but PTD was technically less challenging. The remaining five studies included small case series and case reports. All of them reported the successful useful of PTD with or without technical variations. CONCLUSIONS: Our review concludes, with limited level of evidence that PTD fixation is a safe and efficient technique for treating HGLS patients. It is technically less demanding than a circumferential fusion, even though proper screw insertion is more demanding than conventional pedicle screw fixation.


RESUMO OBJETIVOS: O tratamento cirúrgico das listeses de alto grau da coluna lombar (LAGCL) é complexo, objetivando alcançar uma fusão sólida capaz de suportar o estresse biomecânico da junção lombo-sacra, bem como descompressão do tecido neural. Realizamos revisão sistemática da literatura para avaliar a segurança e a eficácia da fixação transdiscal (FTD) L5S1 em LAGCL e suas variações. MÉTODOS: Realizamos revisão sistemática conforme metodologia Prisma na base de dados PubMed dos estudos que utilizaram FTD no tratamento das LAGCL e suas variações. Dados clínicos e radiológicos foram extraídos dos trabalhos e discutidos. A qualidade dos estudos foi avaliada segundo o Oxford Centre for Evidence-Based Medicine Levels of Evidence. RESULTADOS: Sete estudos foram incluídos e analisados, todos com nível IV de evidência. Dois estudos tinham séries de casos maiores, comparando diferentes técnicas cirúrgicas: um concluiu que a FTD foi associada a melhor prognóstico clínico quando comparada à fixação pedicular tradicional, e o outro sugeriu que os resultados clínicos e radiológicos com a FTD foram semelhantes à fusão intersomática, porém com menor demanda técnica na FTD. Os demais cinco estudos eram pequenas séries ou relatos de casos. Todos reportaram o uso da FTD com sucesso, com e sem variações da técnica. CONCLUSÃO: Concluímos que, embora com evidências limitadas, a FTD é segura e efetiva no tratamento das LAGCL. É tecnicamente mais simples do que a fusão circunferencial (intersomática), porém com maior complexidade que a fixação pedicular convencional.
