RESUMO

OBJECTIVE: This study aims to compare the effects of microscopic microdiscectomy and microendoscopic discectomy on pain, disability, fear of falling, kinesiophobia, anxiety, quality of life in patients with lumbar disc herniation (LDH). METHODS: A total of 90 patients who underwent microscopic microdiscectomy (n = 40) and microendoscopic discectomy (n = 50) for LDH were included in this study. The patients' pain, disability, fear of falling, kinesiophobia, anxiety, and quality of life were evaluated before the surgery, in the early postoperative period and three months after. RESULTS: In patients who underwent microendoscopic discectomy, the results of pain, disability, fear of falling, kinesiophobia and anxiety were statistically decreased compared with the microscopic microdiscectomy in the early postoperative period and three months later (p < 0.05). Also, a statistically higher increase was observed in the general health perception of patients who underwent microendoscopic discectomy three months after the operation (p < 0.01). CONCLUSION: Microendoscopic microdiscectomy, remains the most effective and widely applied method with advantages on pain, quality of life, and improved physical functions.

CONCLUSIÓN: La microdiscectomía microendoscópica sigue siendo el método más eficaz y ampliamente aplicado con ventajas sobre el dolor, la calidad de vida y la mejora de las funciones físicas.

RESUMO

INTRODUCTION: In addition to pain, specific low back pain is frequently accompanied by restricted range of motion (ROM) during gait. PURPOSE: To compare the behavior of kinematic and spatiotemporal gait parameters, pain, functional status, and self-efficacy, in patients with a diagnosis of herniated disk or lumbar stenosis undergoing surgery, in the pre- and postoperative periods of 1 and 6 months (PO6). METHODS: Seven participants and 11 control subjects were assessed. A kinematics system comprising 10 optoelectronic cameras was used to assess gait. The Roland-Morris questionnaire, pain intensity, and self-efficacy, over three periods, were used. RESULTS: The ROM of the pelvis, hip, and knee of the hernia group presented an increase after surgery and the stenosis group presented a reduction of values in the hip. During the stance phase, the pelvis and hip ROM of both groups remained smaller than the control group. There was improvement in pain in individuals with hernia and stenosis (effect size = 0.6 and 0.8, respectively) in the three analyzed moments; for functional status there was improvement in the first postoperative period (ES = 0.4) compared to the preoperative in those individuals with hernia; and those with stenosis had improvement at PO6 when compared to the time before the surgery (ES = 0.2). CONCLUSION: Surgical intervention modifies the spatiotemporal parameters, the ROM of the pelvis, hip, and knee in the total gait cycle, primarily in the sagittal plane, and causes alterations, particularly in the hip joint, in these individuals during the support phase.

RESUMO

BACKGROUND: In the literature, degenerative cervical disc herniation is considered to occur more frequently at the C5-C6 and C6-C7 levels. This study aimed to evaluate the operated cervical level prevalence among patients with degenerative cervical disc herniation in a Hispanic Puerto Rico population. METHODS: The University of Puerto Rico Neurosurgery database was used to identify patients who underwent anterior cervical discectomy for degenerative cervical disc herniation during a 15-year period from January 1, 2006 until December 31, 2020. Operated cervical levels for each patient were analyzed. RESULTS: During the study period, 409 patients were operated on for degenerative cervical disc herniation. Two hundred-eight patients (50.8%) had disc herniations at more than 1 cervical level for 663 treated levels. The most prevalent cervical levels in this Hispanic population were C5-C6 (34.8%) and C4-C5 (28.1%). The C6-C7 level was involved in 18.9% of the operated levels, and the C3-C4 level in 17.3%. The C7-T1 level was involved in only 0.6% of the operated levels, and the C2-3 level in 0.3%. The cohort included 51.3% of men and 48.7% of women, with a men-to-women ratio of 1.05:1. The median age of females was 56.5 (range 26-82) and 59.0 (range 31-85) for males. Operated cervical discs were most common between the ages of 48 and 66 years for either sex. CONCLUSIONS: In a Hispanic Puerto Rico population, the most prevalent operated degenerative cervical disc levels were C5-C6 and C4-C5.

RESUMO

BACKGROUND: Thirty years have passed since Kambin's first clinical series of lumbar disc herniations (LDH) treated by arthroscopic microdiscectomy. Despite several advances in this interim, sequestrated LDHs over the dorsal aspect of the dura, and high-grade up- or downward disc migration have been a relative limitation of the transforaminal endoscopic technique. The interlaminar window was the next step to deal with such highly migrated LDHs. Favorable outcomes were obtained in 70-90% of the patients in the long-term, but recurrence rates remained high (approximately 12%), and the approach could be limited by the size of the interlaminar window. Few relevant studies have addressed the role of translaminar full endoscopic technique for migrated LDHs. To describe an innovative modification of the translaminar full endoscopic approach with Tom Shidi needles. METHODS: This technical modification is presented in a detailed fashion for treating these challenging LDHs and illustrated through a clinical case. RESULTS: The patient underwent successful translaminar full endoscopic technique with complete pain resolution postoperatively. The postprocedural course was uneventful. A follow-up imaging showed no evidence of residual LDHs fragments. CONCLUSIONS: Translaminar full endoscopic technique with Tom Shidi needles is a promising modification of the previously presented interlaminar and translaminar endoscopic routes in the treatment of migrated LDHs to fasten surgical procedures and increase the safety of spinal canal manipulation.

RESUMO

Thoracic disc herniation is a rare pathology compared to the rest of the herniated discs. Due to their difficult access to the area of compromise and proximity to the spinal cord they represent a real challenge for the spine surgeon. The objective is to report an atypical case with three symptomatic dorsal disc herniations which required surgical treatment. Surgery was performed in two times with a lapse of 12 months between interventions. It was done a minimally invasive transthoracic decompression and intersomatic arthrodesis without instrumentation. The patient presented good neurological recovery without any serious sequelae.

La hernia de disco dorsal es una afección poco frecuente en comparación con el resto de las hernias discales. Por su difícil acceso a la zona de compromiso y cercanía de la médula espinal representan un verdadero desafío para el cirujano de columna. El objetivo del trabajo es presentar un caso atípico con tres hernias de disco dorsales sintomáticas en forma sincrónica que requirió tratamiento quirúrgico. La cirugía se hizo en dos tiempos con un lapso de 12 meses entre las intervenciones. Se realizó descompresión transtorácica mínimamente invasiva y artrodesis intersomática sin instrumentación en cada nivel. El paciente presentó buena recuperación neurológica sin ninguna secuela grave.

RESUMO

OBJECTIVE: In this randomized and prospective research, we aimed to relieve surgical and muscle-related pain early after lumbar disc operations with caudal preemptive analgesia. MATERIALS AND METHODS: A total of 120 patients with single-level lumbar disc herniation were included in this study. The caudal epidural injection was performed for all patients 20 min before surgery. The patients were divided into three groups. Non-steroidal anti-inflammatory drugs or tramadol use were recorded. Pre-operative and post-operative pain was interpreted through a visual analog scale. RESULTS: There was a difference between the groups in all post-operative measurements (p < 0.05), between Group 1 and Group 3, and between Group 2 and Group 3. A statistical significance has been achieved between the groups at the 1st h, 2nd h, 4th h, and 24th h (p < 0.05). The difference between the pain intensities of the patients at the 24th h and the 1st week was statistically significant in Groups 1 and 2 (p < 0.05). Evaluation of the effects of medical treatments reduced the severity of back pain and foot pain. CONCLUSION: The preemptive bupivacaine or in combination with methylprednisolone caudal injection is an effective and safe method to reduce post-operative pain and ameliorate functional capacity for the treatment of lumbar disc herniation.

OBJETIVO: En esta investigación prospectiva aleatorizada, nuestro objetivo fue aliviar el dolor quirúrgico y muscular temprano después de las operaciones de disco lumbar con analgesia preventiva caudal. MATERIALES Y MÉTODOS: en este estudio se incluyeron un total de 120 pacientes con hernia de disco lumbar de un solo nivel. La inyección epidural caudal se realizó para todos los pacientes 20 minutos antes de la cirugía. Los pacientes fueron divididos en tres grupos. Se registró el uso de AINE o tramadol. El dolor preoperatorio y postoperatorio se interpretó a través de una escala analógica visual. RESULTADOS: Hubo diferencia entre los grupos en todas las medidas postoperatorias (p < 0.05), entre el grupo 1 y el grupo 3, y entre el grupo 2 y el grupo 3. Se ha logrado una significación estadística entre los grupos a la 1a hora, 2a hora, 4 y 24 horas (p < 0.05). La diferencia entre las intensidades de dolor de los pacientes a la hora 24 y la primera semana fue estadísticamente significativa en los Grupos 1 y 2 (p < 0.05). La evaluación de los efectos de los tratamientos médicos redujo la gravedad del dolor de espalda y de pie. CONCLUSIÓN: La bupivacaína preventiva, o en combinación con la inyección caudal de metilprednisolona, es un método eficaz y seguro para reducir el dolor posoperatorio y mejorar la capacidad funcional para el tratamiento de la hernia de disco lumbar.

RESUMO

BACKGROUND: The aim of the study was to explore the safety and efficacy of percutaneous transforaminal endoscopic discectomy (PTED) and fenestration discectomy (FD) in the treatment of lumbar disc herniation (LDH). MATERIAL AND METHODS: The complete clinical data from 87 patients with LDH from our hospital were retrospectively analyzed. Patients were divided into a control group (n = 39, treated with FD) and a research group (n = 48, treated with PTED) according to the prescribed treatments. The basic operation conditions were compared across the two groups. Surgical outcomes were assessed. The incidences of complications and the life quality of patients were evaluated 1 year after surgery. RESULTS: The patients in both groups completed the operation. The visual analog scale and Oswestry Disability Index score of patients in the research group was significantly lower while the Orthopaedic Association Score was significantly higher after surgery. The success rate of the operation in the research group which was significantly higher and the rate of complications was significantly lower. No statistical differences in the quality of life were observed between the patients (p > 0.05). CONCLUSIONS: PTED and FD are effective in the treatment of LDH. However, our study showed that PTED has a higher rate of treatment success, faster recovery times and is safer than FD.

OBJETIVO: Investigar la seguridad y la eficacia de la discectomía endoscópica percutánea (DEP) y de la discectomía fenestrada (DF) en el tratamiento de la hernia de disco lumbar. MÉTODO: Se analizaron retrospectivamente los datos clínicos completos de 87 pacientes con hernia de disco lumbar. De acuerdo con el tratamiento prescrito, los pacientes fueron divididos en grupo control (DF, n = 39) y grupo de estudio (DEP, n = 48). Se compararon las condiciones básicas de funcionamiento de los dos grupos y se evaluaron los resultados de la cirugía, la incidencia de complicaciones y la calidad de vida al año de la operación. RESULTADOS: Ambos grupos completaron la operación. En el grupo de estudio, las puntuaciones en la escala visual análoga y ODI disminuyeron significativamente, mientras que las puntuaciones JOA aumentaron significativamente. La tasa de éxito de la operación en el grupo de estudio fue significativamente mayor que en el grupo control, y la incidencia de complicaciones fue significativamente menor que en el grupo control. No hubo diferencia significativa en la calidad de vida entre los dos grupos (p > 0.05). CONCLUSIONES: La tasa de éxito del tratamiento con DEP fue mayor, y el tiempo de recuperación fue más rápido y más seguro que con la DF.

RESUMO

INTRODUCTION: Surgical intervention is the treatment of choice in patients with thoracic disc herniation with refractory symptoms and progressive myelopathy. Due to high occurrence of complications from open surgery, minimally invasive approaches are desirable. Nowadays, endoscopic techniques have become increasingly popular and full-endoscopic surgery can be performed in the thoracic spine with low complication rates. METHODS: Cochrane Central, PubMed, and Embase databases were systematically searched for studies that evaluated patients who underwent full-endoscopic spine thoracic surgery. The outcomes of interest were dural tear, myelopathy, epidural hematoma, recurrent disc herniation, and dysesthesia. In the absence of comparative studies, a single-arm meta-analysis was performed. RESULTS: We included 13 studies with a total of 285 patients. Follow-up ranged from 6 to 89 months, age from 17 to 82 years, with 56.5% male. The procedure was performed under local anesthesia with sedation in 222 patients (77.9%). A transforaminal approach was used in 88.1% of the cases. There were no cases of infection or death reported. The data showed a pooled incidence of outcomes as follows, with their respective 95% confidence intervals (CI)-dural tear (1.3%; 95% CI 0-2.6%); dysesthesia (4.7%; 95% CI 2.0-7.3%); recurrent disc herniation (2.9%; 95% CI 0.6-5.2%); myelopathy (2.1%; 95% CI 0.4-3.8%); epidural hematoma (1.1%; 95% CI 0.2-2.5%); and reoperation (1.7%; 95% CI 0.1-3.4%). CONCLUSION: Full-endoscopic discectomy has a low incidence of adverse outcomes in patients with thoracic disc herniations. Controlled studies, ideally randomized, are warranted to establish the comparative efficacy and safety of the endoscopic approach relative to open surgery.

RESUMO

INTRODUCTION: there are numerous classifications for herniated discs, such classifications guide professionals about the severity of the lesion, the possible clinical picture of the patient, the most appropriate treatment and are undoubtedly a predictive tool to project the possible results of the therapies used. The main purpose of this work is to validate the inter- and intra-observer reliability of the Michigan State University (MSU) classification among the spine surgeons of our service and also to know the risk factors associated with the patients who underwent lumbar discectomy, the most affected disc level, the clinical presentation and the previous treatments performed in the patients treated by our team. MATERIAL AND METHODS: 50 nuclear magnetic resonance (MR) images in axial T2 section corresponding to the "maximum disc herniation" level were selected from patients diagnosed and submitted to meningo-radicular release surgery and single level lumbar discectomy retrospectively in the last two years from our database; these images were distributed among three spine surgeons of our institution. The three spine surgeons gave a specific classification for each MR image based on the MSU classification, then at an interval of seven days one of the three surgeons reclassified the images. The degree of agreement between surgeons was analyzed by calculating interobserver and intraobserver reliability using kappa statistical analysis. RESULTS: the analysis of the kappa coefficient indicated that most of the comparisons by observer gave a "good" concordance strength, the kappa index was higher than 0.64 in all the possible comparisons of the observations. In relation to the number of coincidences, in 60% of the patients there was a total coincidence between the three surgeons, with two coincidences in 24%, and in 16% there was no coincidence at all. For the intraobserver analysis the kappa index was 0.953 with a very good concordance strength, the observed agreement was 96%. CONCLUSION: our research shows a good reliability in the MSU classification among spine surgeons of our institution, as well as very good when reclassifying the intraobserver; we believe that having a sagittal MRI slice to classify them would be very useful, more research is needed to give a prognostic value to the location and size of the hernia and its relation with the surgical indication.

INTRODUCCIÓN: existen numerosas clasificaciones para las hernias de disco, dichas clasificaciones orientan a los profesionales acerca de la gravedad de la lesión, del posible cuadro clínico del paciente, del tratamiento más adecuado y constituyen, sin lugar a dudas, una herramienta predictiva para proyectar los posibles resultados de las terapias utilizadas. El propósito principal de este trabajo es validar la confiabilidad interobservador e intraobservador de la clasificación de la Universidad Estatal de Míchigan (MSU) entre los cirujanos de columna de nuestro servicio y además, conocer los factores de riesgo asociados con los pacientes que fueron intervenidos con discectomía lumbar, el nivel de disco más afectado, la presentación clínica y los tratamientos previos realizados en los pacientes tratados por nuestro equipo. MATERIAL Y MÉTODOS: fueron seleccionadas 50 imágenes de resonancia magnética nuclear (RM) en el corte axial de T2 correspondiente al nivel de "hernia discal máxima" de pacientes diagnosticados y sometidos a cirugía de liberación meningo radicular y discectomía lumbar de un solo nivel de manera retrospectiva en los últimos dos años de nuestra base de datos, estas imágenes se distribuyeron entre tres cirujanos especialistas en columna de nuestra institución. Los tres cirujanos de columna dieron una clasificación específica para cada imagen de RM basada en la clasificación de la MSU, luego en un intervalo de siete días uno de los tres cirujanos volvió a clasificar las imágenes. El grado de acuerdo entre los cirujanos se analizó calculando la confiabilidad interobservador e intraobservador mediante el análisis estadístico kappa. RESULTADOS: el análisis del coeficiente de kappa indicó que en la mayoría de las comparaciones por observador dieron una fuerza de concordancia "buena", el índice de kappa fue superior a 0.64 en todas las posibles comparaciones de las observaciones. En relación con la cantidad de coincidencias, en 60% de los pacientes hubo una coincidencia total entre los tres cirujanos, con dos coincidencias 24% y en 16% no hubo ninguna coincidencia. Para el análisis intraobservador el índice de kappa fue de 0.953 con una fuerza de concordancia muy buena, el acuerdo observado fue de 96%. CONCLUSIÓN: nuestra investigación demuestra una confiabilidad buena en la clasificación de la MSU entre cirujanos de columna de nuestra institución así como muy buena al reclasificar el intraobservador. Creemos que tener un corte sagital de RM para clasificarlas sería de gran utilidad. Se necesitan más investigaciones para dar un valor pronóstico a la ubicación y tamaño de la hernia y su relación con la indicación quirúrgica.

RESUMO

BACKGROUND: Traumatic facet dislocations in the subaxial cervical spine, also known as locked facets, are commonly associated with neurological deficits. The fear of the presence of an associated traumatic disc herniation and consequent neurological worsening usually causes a delay in the spinal realignment. This study's aim is an analysis of safety and efficacy when treating acute cervical traumatic facet dislocations using cranial-cervical traction or posterior open reduction and fixation in the presence of disc herniations. METHODS: Inclusion criteria addressed the following patient groups: (1) MRI diagnosis of traumatic cervical facet dislocations with disc herniation, (2) intervention: either cranial-cervical traction or posterior open reduction and fixation, (4) neurological outcomes after treatment, (5) adult 18 plus years of age, (6) sample sizes greater than 20 patients, (7) English language publication. The following databases and search tools were analyzed: MEDLINE (PubMed), Cochrane Central Register of Controlled Trials (CENTRAL), Google Scholar, and the clinical trial registries (ClinicalTrials.gov), October 2021. RESULTS: Six studies were found, 2 with posterior open reduction and fixation and 4 with cranial-cervical traction, totalizing 197 patients. Neurological worsening was reported only in 1 case (0.5%). CONCLUSIONS: Traumatic disc herniation in cervical facet dislocations is not an absolute contraindication of cranial-cervical traction or posterior open reduction. Early realignment of the spine could bring more neurological benefits than waiting for an MRI or surgical discectomy. However, caution is needed in this review's data interpretation until prospective and well-designed studies are performed.

RESUMO

OBJECTIVE: The objective of this study is to compare the clinical outcome among patients who are surgically treated for lumbar disc herniation by transforaminal and interlaminar endoscopy techniques. METHODS: For the treatment of lumbar disc herniation, 31 patients were assigned to undergo the interlaminar technique and 24 patients the transforaminal technique. They were evaluated using visual analog scale and Oswestry disability index in the preoperative period, in the first postoperative period, and in the 12th month after the procedure. The clinical results between the two techniques were then compared. RESULTS: Overall, 89.1% of the patients obtained good results, with 12.5% complications in the transforaminal technique and 9.6% in the interlaminar technique. CONCLUSION: Although both the endoscopic techniques, compared in this study, are safe and effective for the surgical treatment of lumbar herniated disc, the interlaminar technique presented significantly better results and lower rates of complications than the transforaminal technique.

RESUMO

BACKGROUND: Neural mobilization (NM) techniques have been shown to improve the neural tissue's viscoelastic properties that may lead to recover of the function of the nerve after lumbar spine surgery. This study aimed to determine the effects of NM in addition to standard rehabilitation on lumbar and sciatic pain intensity, disability level, and quality of life in patients after receiving a microdiscectomy of the intervertebral lumbar disc (IVD). METHODS: Twenty-four participants (age 41.3 ± 8.3 years old) within 3-4 weeks of a microdiscectomy of an IVD were randomly allocated to control (CTRL; n = 12) or NM group (n = 12). The CTRL group received ten standard rehabilitation sessions. The NM group received the same rehabilitation sessions with the addition of NM techniques. The intensity of lumbar and sciatic pain (visual analogue scale), disability level (Oswestry disability index), and health-related quality of life (SF-36 questionnaire) were measured before and after the intervention. RESULTS: Within-group analysis revealed a significant reduction in lumbar (p < 0.05) and sciatic pain intensity (p < 0.001), disability level (p < 0.001), and improvement in the physical function and problems, vitality, emotional well-being, and pain SF-36 items (p < 0.05) in both groups. There were no statistical differences between groups in all outcomes. CONCLUSION: A standard rehabilitation protocol alone or in combination with NM techniques are equally effective in reducing pain and disability level, as well as improving quality of life in patients after a microdiscectomy due to intervertebral lumbar disc lesion.

RESUMO

Summary Cervical and root pain due to herniated disc is one a common cause of a visit to an orthopedic surgeon. It is important to know how to diagnose, treat and initially. What are the best options to treat a herniated disc nowadays? The present article reviews the literature and updates on the clinical and surgical treatment of cervical disc herniation.

Resumo A dor cervical e radicular devido à hérnia de disco é uma causa comum de uma visita a um cirurgião ortopédico. É importante saber diagnosticar, tratar e inicialmente. Quais são as melhores opções para tratar a hérnia de disco hoje em dia? Este artigo faz uma revisão da literatura e atualização sobre o tratamento clínico e cirúrgico da herniação do disco cervical.

RESUMO

Lumbar disc herniation (LDH) is a relatively common pathology usually presenting with unilateral radiculopathy ipsilateral to the disc herniation. Some patients can present with contralateral radicular symptoms. The objective of this article is to review the current literature on lumbar disc herniations with contralateral radiculopathy regarding its pathophysiology and surgical strategies. A systematic review of the literature on LDH with contralateral radiculopathy was performed using MEDLINE (via PubMed) using MeSH terms. This review was done following recommendations of PRISMA statement and PICOT strategy of search. Initial electronic search identified 126 papers. Finally, 18 articles were reviewed. None of the included papers was described as comparative. Pathophysiological processes underlying contralateral pain may include prominent spondylotic changes and the accompanying stenosis; hypertrophic yellow ligament; dural attachments along the posterior longitudinal ligament; nerve root traction forces; and friction radiculitis, migrated epidural fat, nerve root anomaly, and venous congestion inside the vertebral canal. In our pooled analysis, 11 patients reported were treated by bilateral approach with 100% of clinical success and no complications. Eight patients were treated by unilateral approach ipsilateral to pain with 100% of clinical success and no complications. Forty-eight patients were treated by unilateral approach ipsilateral to herniation with 100% of clinical success and no complications. Pathophysiology underlying contralateral pain in LDH is probably multifactorial. There is not enough scientific evidence to define the best surgical approach for patients with LDH and contralateral pain.

RESUMO

Resumen: Introducción: el síndrome de cola de caballo (SCC) es una entidad poco frecuente, provocado por la compresión de las raíces nerviosas en el canal a nivel de la cola de caballo. Puede dejar graves secuelas si no es diagnosticado y tratado de forma precoz. Únicamente 2% a 6% de las hernias discales lumbares van a provocar un SCC. El diagnóstico de esta patología se basa en criterios clínicos, siendo éstos objeto de controversia dada la variabilidad de presentación del cuadro clínico. El objetivo de este trabajo es analizar la presentación clínica y evolución posoperatoria de los pacientes intervenidos por SCC secundaria a hernia de disco por equipo del Centro de Deformidades de Columna (CE.DEF.CO), entre enero de 2009 y diciembre de 2018. Material y método: realizamos un análisis retrospectivo. La población objetivo son los pacientes intervenidos por SCC secundario a hernia discal entre enero de 2009 y diciembre de 2018 por equipo del CE.DEF.CO. Analizamos 20 pacientes intervenidos quirúrgicamente, de ellos 17 (85%) casos presentaron síntomas urinarios, 18 (90%) casos dolor o elementos deficitarios en miembros inferiores, 13 casos anestesia/hipoestesia en silla de montar, 6 casos síntomas intestinales y 3 casos presentaron disfunciones sexuales. En 19 casos se realizó procedimiento quirúrgico antes de las 48 de iniciados los síntomas. Resultados: la remisión de síntomas esfinterianos al mes es de 83% y al año posoperatorio de casi 87%. Se constató un caso de disfunción sexual al año posoperatorio. Conclusión: el diagnóstico precoz por el médico emergencista es fundamental, por lo que el conocimiento de esta patología es imprescindible. Nuestros resultados en pacientes intervenidos de forma precoz, antes de las 48 horas, fueron similares a los publicados en la bibliografía internacional con bajo porcentaje de secuelas.

Summary: Introduction: cauda equina syndrome (CES) is a rare entity, caused by compression of the nerve roots in the spinal canal at the cauda equina level. It can leave serious sequelae if it is not diagnosed and treated early. Only 2-6% of lumbar disc herniation will cause CES. The diagnosis of this pathology is based on clinical criteria, these being the subject of controversy given the variability of presentation of the clinical picture. Materials and methods: we conducted a retrospective study. The target population are the patients operated on for CES secondary to herniated disc between January 2009 and December 2018 by a team from CE.DEF.CO. (center for spinal deformities). The objective is to carry out a set-up regarding the clinical presentation of this entity and to evaluate the correlation between surgical time and neurological improvement. Out of 20 patients who were operated, 17 (85%) presented urinary symptoms, 18 (90%) were patients in pain or presenting deficit elements in the lower limbs, 13 were cases of anesthesia / hypoesthesia in the saddle, 6 cases evidenced intestinal symptoms and 3 cases presented sexual dysfunction. In 19 cases, a surgical procedure was performed before 48 hours after symptoms started. Results: the remission of sphincter symptoms after one month is 83% and it rises to almost 87% one year after the surgery. One case of sexual dysfunction persisted one year after surgery. Conclusion: early diagnosis by the emergency physician is essential, so knowledge of this pathology is essential. Our experience and good results allow us to conclude that early surgical treatment is associated with symptomatic improvement and fewer neurological sequelae in the short and long term.

Resumo: Introdução: a síndrome da cauda eqüina (SCE) é uma entidade rara causada pela compressão das raízes nervosas no canal no nível da cauda eqüina. Pode deixar seqüelas graves se não for diagnosticada e tratada precocemente. Apenas 2-6% das hérnias do disco lombar causarão a síndrome da cauda eqüina. O diagnóstico desta patologia é baseado em critérios clínicos, sendo este motivo de controvérsia, dada a variabilidade da apresentação do quadro clínico. Materiais e métodos: realizamos um estudo retrospectivo. A população-alvo estava composta por pacientes operados por SCE secundária a hérnia discal entre janeiro de 2009 e dezembro de 2018 pela equipe do CE. DEF.CO (Centro de Defeitos da Coluna Vertebral). Foram analisados 20 pacientes operados, dos quais 17 (85%) apresentaram sintomas urinários, 18 (90%) dor ou elementos de deficiência em membros inferiores, 13 anestesia / hipoestesia em sela, 6 sintomas intestinais e 3 disfunções sexuais. Em 19 casos, um procedimento cirúrgico foi realizado antes de 48 horas após o início dos sintomas. Resultado: a remissão dos sintomas esfincterianos em um mês é de 83% e em um ano pós-operatório é de quase 87%. Um caso de disfunções sexuais foi encontrado um ano após a cirurgia. Conclusão: o diagnóstico precoce pelo médico de emergência é essencial, portanto o conhecimento desta patologia é fundamental. Nossos resultados em pacientes operados precocemente, antes de 48 horas, foram semelhantes aos publicados na literatura internacional com baixo percentual de seqüelas.

RESUMO

RESUMEN Fundamento: La enfermedad degenerativa cervical produce una variedad de síntomas clínicos que pueden ser tratados de forma no quirúrgica, sin embargo en ocasiones la cirugía es necesaria. La técnica quirúrgica más empleada para tratar esta enfermedad es la discectomía con artrodesis. El tratamiento adecuado de la hernia discal cervical depende de una adecuada selección de la técnica quirúrgica y su correcta realización. Objetivo: Caracterizar el tratamiento quirúrgico de la hernia discal cervical en el Hospital Provincial General Camilo Cienfuegos de Sancti Spíritus en el período: enero de 2015 a diciembre de 2018. Metodología: Se realizó un estudio prospectivo en el Hospital Provincial General Camilo Cienfuegos de Sancti Spíritus de enero 2015 a diciembre 2018. La población de estudio: todos los pacientes que acudieron a la consulta externa de neurocirugía del hospital refiriendo cervicalgia o cervicobraquialgia; la muestra: 51 pacientes diagnosticados por resonancia magnética nuclear de hernia discal cervical y que se les realizó al menos una discectomía cervical. Resultados: De los pacientes el 62.8 % eran mujeres y el 33.3 % tenía una edad comprendida entre 51-60 años. El espacio intervertebral más afectado fue C5-C6 (43.7 %). La técnica quirúrgica que predominó fue la discectomía con colocación de injerto autólogo (79.7 %). La complicación más frecuente fue la expulsión del injerto (3.9 %). Conclusiones: El comportamiento de la hernia discal en cuanto al sexo, edad y nivel afectado fue similar al descrito en la bibliografía. La técnica quirúrgica más empleada fue la artrodesis con injerto autólogo de cresta ilíaca. Las complicaciones presentadas fueron infrecuentes.

ABSTRACT Background: Cervical degenerative disease produces a variety of clinical symptoms that can be treated by a non-surgical way, however sometimes surgery is necessary. The most widely used surgical technique to treat this disease is discectomy with arthrodesis. The proper treatment of cervical disc herniation depends on an adequate selection of the surgical technique and its correct performance. Objective: To characterize the surgical treatment of cervical disc herniation at Camilo Cienfuegos General Provincial Hospital in Sancti Spíritus in the period: January 2015 to December 2018. Methodology: A prospective study was carried out at Camilo Cienfuegos General Provincial Hospital in Sancti Spíritus from January 2015 to December 2018. The study population: all the patients who attended the hospital outpatient neurosurgery consultation referring cervicalgia or cervicobraquialgia; the sample: 51 patients diagnosed with cervical disc herniation and performed at least one cervical discectomy. Results: Of the patients, 62.8 % were women and 33.3 % were between 51-60 years old. The most affected intervertebral space was C5-C6 (43.7 %). The predominant surgical technique was discectomy with autologous graft placement (79.7 %). The most frequent complication was the expulsion of the graft (3.9 %). Conclusions: The behavior of the herniation disc concerning sex, age and affected level was similar to that described in the literature. The most widely used surgical technique was arthrodesis with an autologous iliac crest graft. The complications presented were infrequent.
