ABSTRACT

OBJECTIVE: To compare results of Plate-Graff, Plate-Cage and PEEK cage in patients with cervical stenosis. MATERIAL AND METHODS: Prospective, with before and after intervention and comparative study. From January 2005 to October 2011 we included 37 patients (male: 48.6%, female: 51.4%) post-surgery by anterior approach; 3 groups via: Group I, arthrodesis with Plate-Graff n = 12 (M 41.7%, F 58.3%) with 22 levels, group II, Plate-Cage n = 11 (M 63.6% 36.4% F) 19 levels, group III, PEEK cage, n = 14 (M 0% F 50%) with 25 levels. Functional assessment pre- and postoperative with neck disability index (NDI) and visual analogue scale for pain (VAS). The radiological assessment with X-rays only. Descriptive statistics were obtained. Wilcoxon method use according to data distribution, non parametric tests of ranges with sign of Kruskal-Wallis for comparison between more than two groups, and significance level with p 0.05. We used the statistical package SPSS version 15. RESULTS: The majority of patients was found between the sixth and eighth decade of life. At one year of follow up the NDI and pain with VAS shown improvement with statistical difference in three groups (p = 0.001). However, the radiographic measurements per year of follow-up showed a significant improvement of segmental lordosis (p = 0.02) only in patients with Plate-Graff. CONCLUSIONS: Using the graft offers best clinical and radiographic results compared with the Plate Cage and box peek to one year of follow-up.


OBJETIVO: Comparar resultados de placa-injerto, caja-placa y caja-PEEK, en pacientes con conducto cervical estrecho. MATERIAL Y MÉTODOS: Estudio prospectivo, en panel antes y después, de intervención y comparativo. De Enero de 2005 a Octubre de 2011, muestra de 37 pacientes (masculino: 48.6%, femenino: 51.4%) postoperados por vía anterior; formando tres grupos: grupo I, artrodesis con placa-injerto n = 12 (M 41.7%, F 58.3%) con 22 niveles; grupo II, caja-placa n = 11 (M 63.6%, F 36.4%) con 19 niveles; grupo III, caja-PEEK, n = 14 (M 50%, F 50%) con 25 niveles.

ABSTRACT

INTRODUCTION: The technique of placement of pedicle screws has gradually improved, but even misplacement observed in 1.2 to 20% of cases, have appeared techniques fluoroscopic, tomographic and electromagnetic navigation, which led it to 1.3 to 4.3%, but nevertheless they are expensive and complex technologies. Present technique pedicle screw placement by using templates with a modification in the art, performing tomography and reconstruction in the same surgical position and with the templates of 3 or more levels. METHODS: Five cases of idiopathic scoliosis were performed, with correction and instrumentation with pedicular screws, where a three-dimensional model of the spine was performed with a tomography in a surgical position, whose images were exported to a 3D printer to reconstruct the desired trajectory of the screws in a template using cylinders resting on the inverse surface of the vertebrae. The direction of the screw was planned in the center of the pedicle and parallel to the upper platform of the vertebra. Each template was of several levels and transoperative X-rays were not used. RESULTS: Under electrophysiologic monitoring transoperative «red alerts¼ were not reported, the placement of the screws in postoperative CT scan was evaluated, showing a standard deviation in placement of 1.9 and 2.2 mm on the right and left respectively pedicles, with respect to their planning. DISCUSSION: This technique is simple and safe, besides not requiring great technology, its use is suggested in beginner spine surgeons and in severe deformities, it can be performed in any hospital where spinal surgery is performed.


INTRODUCCIÓN: La técnica de colocación de tornillos transpediculares ha mejorado paulatinamente, a pesar de ello, la mala colocación oscila entre 1.2 al 20% de los casos; han surgido técnicas de navegación asistidas por flouroscopía, tomografía y resonancia magnética mejorando el índice de falla al 1.3-4.3%. La presente técnica de colocación utiliza plantillas con la modificación de que la tomografía y la reconstrucción son realizadas con el paciente en la posición quirúrgica, además que las plantillas abarcan tres o más niveles. MÉTODOS: Se presentan cinco casos de escoliosis idiopática tratados con instrumentación y colocación de tornillos transpediculares donde se generó un modelo tridimensional de la columna en posición quirúrgica; las imágenes fueron exportadas a una impresora 3-D para reconstruir la trayectoria apropiada de los tornillos, la dirección de éstos fue planeada tomando de referencia el centro del pedículo y paralela a la plataforma superior de la vértebra. Cada plantilla consta de diferentes niveles y no se requirió del uso de rayos X trans­operatorios. RESULTADOS: Bajo monitoreo electrofisiológico transquirúrgico no se reportó ninguna «alerta roja¼; la evaluación postoperatoria por tomografía de la colocación de los tornillos mostró una desviación estándar de 1.9 y 2.2 mm tanto a la derecha y a la izquierda, respectivamente, de acuerdo con lo planeado. DISCUSIÓN: La técnica es simple y segura, no requiere de mucho despliegue tecnológico, se sugiere su uso para los cirujanos de columna con poca experiencia y para deformidades severas; consideramos que puede desarrollarse en cualquier hospital donde se realice cirugía de columna.

ABSTRACT

INTRODUCTION: A variety of systems have been developed to fix and perform arthrodesis of the cervical spine, with the advantages of reducing the risk of pseudoarthrosis, extrusion and graft collapse and achieving a more precise sagittal alignment. We therefore need to compare the results of the following approaches to patients with cervical stenosis: plate-graft, cage-plate and PEEK cage. MATERIAL AND METHODS: Prospective, interventional, comparative trial involving three groups: group I, arthrodesis with plate-graft; group II, cage-plate, and group III, PEEK cage. The pre- and postoperative assessments included the cervical disability scale, the pain visual analog scale (VAS), and cervical spine X-rays. The results were analyzed with non-parametric tests such as the Wilcoxon sign test and the Kruskal-Wallis test for the comparison of more than two groups. Significance level was 0.05. RESULTS: The sample included a total of 37 patients: n = 12 in group I, with 22 levels; n = 11 in group II, with 19 levels, and n = 14 in group III, with 25 levels. Patient age ranged between 60 and 80. One year after surgery there was an improvement in cervical disability and the pain VAS score, with a statistically significant difference among the three groups (p = 0.001). However, radiographic measurements at that time showed a significant improvement in segmental lordosis (p = 0.02) only in plate-graft patients. CONCLUSIONS: The plate-graft approach provides better clinical and radiographic results compared to the cage-plate and PEEK cage techniques, at the one-year follow- up.

ABSTRACT

Adult scoliosis is a complex three-dimensional rotational deformity of the spine, resulting from the progressive degeneration of the vertebral elements in middle age, in a previously straight spine; a Cobb angle greater than 10° in the coronal plane, which also alters the sagittal and axial planes. It originates an asymmetrical degenerative disc and facet joint, creating asymmetrical loads and subsequently deformity. The main symptom is axial, radicular pain and neurological deficit. Conservative treatment includes drugs and physical therapy. The epidural injections and facet for selectively blocking nerve roots improves short-term pain. Surgical treatment is reserved for patients with intractable pain, radiculopathy and/ or neurological deficits. There is no consensus for surgical indications, however, it must have a clear understanding of the symptoms and clinical signs. The goal of surgery is to decompress neural elements with restoration, modification of the three-dimensional shape deformity and stabilize the coronal and sagittal balance.

ABSTRACT

INTRODUCTION: Cervical stenosis refers to the narrowing of the spinal canal or the intervertebral foramina at different anatomic levels, secondary to pathologic processes of the vertebral elements. Surgical management is used when conservative management fails. The anterior and posterior approaches are the most frequently used ones, and the surgical options resulting from these approaches are: anterior cervical diskectomy plus fusion, anterior corporectomy plus fusion, laminoplasty, laminectomy and arthroplasty. MATERIAL AND METHOD: This is an ambispective study conducted in 195 patients with a diagnosis of cervical stenosis who required surgical treatment at our hospital from January 1995 to January 2007. The neck disability index questionnaire was applied, as well as the Nurick scale. Descriptive statistics was used with frequency and percentage measures. RESULTS: The review of the National Rehabilitation Institute electronic records from January 1st 1995 to December 31st 2007 showed that 195 patients underwent surgery for cervical stenosis. Females were predominant. The most affected age group was 46-55 years. The most frequently affected level was C5-C6. A significant improvement was seen in the neck disability index due to pain and the Nurick scale. CONCLUSION: According to world literature, mean age of patients with cervical stenosis is 57.2 years, and the most compromised levels were C4-C5 and C5-C6. Improvement was evident according to the neck disability index and the Nurick scale.

ABSTRACT

INTRODUCTION: Ligamentoplasty is a posterior dynamic stabilization method. The purpose of this study is to compare the incidence of adjacent segment disease in patients undergoing decompression and ligamentoplasty versus patients with standard 360 degrees arthrodesis. MATERIAL AND METHODS: Two groups were studied, each with 15 patients. The first group underwent recalibration with fixation (Group A) and the second group recalibration with ligamentoplasty (Group L). The occurrence of adjacent segment degeneration was assessed, together with the presence of adjacent segment disease in both groups. The statistical analysis was performed with the SPSS 17.0 software. RESULTS: Both techniques showed a statistically significant clinical improvement at the six-month postoperative follow-up (p = 0.001). Radiographic findings showed a higher translational instability index at the one-year follow-up in the arthrodesis group. No statistical difference was found in the clinical course or in the rest of the radiographic variables at the 3-year comparison between both groups. The rate of adjacent segment degeneration in Group A was 33.3%, compared with 20% in Group L at the one-year follow-up. Until now, there have been two cases of radiculopathy, one in Group L and one in Group A, both with adjacent segment disease. CONCLUSION: At the 3-year follow-up it is not possible to say that ligamentoplasty, unlike 360 degrees arthrodesis, decreases the rate of adjacent segment disease. However, this technique has promising results.

ABSTRACT

INTRODUCTION: The currently accepted treatment of thoracolumbar fractures is reduction, decompression, fixation and arthrodesis. However, it is not the perfect solution due to the medium- and long-term consequences of arthrodesis, which include the wear of the adjacent segments above and below. Some previous studies have proposed the treatment with fixation without arthrodesis. However, there are no reports on the medium- and long-term clinical and radiographic follow-up. MATERIAL AND METHODS: Two 20-patient groups treated with transpedicular fixation and decompression, one with and one without posterolateral arthrodesis, were compared. CONTROL GROUP: The mean hospital stay was 5 days. The postoperative visual analog scale pain score was 2-3 in 4 patients; the rest were asymptomatic. The functional Oswestry disability index was 8.3%. The functional economic rehabilitation scale was 4.55. Case group: The mean hospital stay was 5 days. The postoperative visual analog scale pain score was 1-2 in 2 patients; the rest were asymptomatic. The functional Oswestry disability index was 6.3%. The functional economic rehabilitation scale was 6.4. CONCLUSIONS: Both groups had very similar results. The group without arthrodesis had better results in the Oswestry functional disability scale and the functional economic rehabilitation scale.

ABSTRACT

Induction of Th1 cytokines, those associated with cell-mediated immunity, is critical for host defense against infection by intracellular pathogens, including mycobacteria. Signaling lymphocytic activation molecule (SLAM, CD150) is a transmembrane protein expressed on lymphocytes that promotes T cell proliferation and IFN-gamma production. The expression and role of SLAM in human infectious disease were investigated using leprosy as a model. We found that SLAM mRNA and protein were more strongly expressed in skin lesions of tuberculoid patients, those with measurable CMI to the pathogen, Mycobacterium leprae, compared with lepromatous patients, who have weak CMI against M. leprae. Peripheral blood T cells from tuberculoid patients showed a striking increase in the level of SLAM expression after stimulation with M. leprae, whereas the expression of SLAM on T cells from lepromatous patients show little change by M. leprae stimulation. Engagement of SLAM by an agonistic mAb up-regulated IFN-gamma production from tuberculoid patients and slightly increased the levels of IFN-gamma in lepromatous patients. In addition, IFN-gamma augmented SLAM expression on M. leprae-stimulated peripheral blood T cells from leprosy patients. Signaling through SLAM after IFN-gamma treatment of Ag-stimulated cells enhanced IFN-gamma production in lepromatous patients to the levels of tuberculoid patients. Our data suggest that the local release of IFN-gamma by M. leprae-activated T cells in tuberculoid leprosy lesions leads to up-regulation of SLAM expression. Ligation of SLAM augments IFN-gamma production in the local microenvironment, creating a positive feedback loop. Failure of T cells from lepromatous leprosy patients to produce IFN-gamma in response to M. leprae contributes to reduced expression of SLAM. Therefore, the activation of SLAM may promote the cell-mediated immune response to intracellular bacterial pathogens.

ABSTRACT

Se presentan 92 pacientes con pénfigo internados durante un período de diez años. De ellos, 50 eran masculimnos y 42 femeninos. Observando como formas clínicas: pénfigo vulgar (79 pacientes), pénfigo vegetante (2 pacientes), pénfigo foliáceo no endémico (6 pacientes) y pénfigo eritematodes (5 pacientes). El 60,8 por ciento correspondieron a formas graves, el 20,6 por ciento a formas moderadas y 18,4 por ciento a formas leves. Más del 50 por ciento de los pacientes graves requirieron dosis superiores a 180 mg/día de 16 ß metilprednisona. La terapéutica esteroidea fue asociada con inmunosupresores (ciclofosmida, azatioprina y metotrexato), daps u oro, mientras que en 10 pacientes no se agregó ninguna medicación y en otros 10 se asoció más de un fármaco en forma sucesiva. Diez pacientes fallecieron, el 50 por ciento por sepsis. Del análisis de la casuística surgen algunas conclusiones: la mejor respuesta terapéutica en pacientes vírgenes de tratamiento; la utilidad del empleo de dosis altas de esteroide desde el inicio; el comportamiento biológico agresivo de algunos pénfigos superficiales; el valor predictivo de la edad y enfermedades concomitantes preexistentes con respecto a la aparición de complicacionmes; el desarrollo de sepsis como primera causa de muerte; la similar incidencia de complicaciones infecciosas, metabólicas y hematológicas, y la trascendencia de enfermedades cardiovasculares preexistentes como factor condicionante del óbito

ABSTRACT

Se presenta un paciente de 59 anos portador de un reticulohistiocitoma del dorso.Se ponen de relieve sus caracteristicas clinicoevolutivas e histiologicas. Como asi tambien, se menciona el seguimiento del mismo en un periodo de 5 anos, al cabo del cual sufre una recidiva local. Se hace una revision bibliografica del tema y se intenta ubicarlo dentro de la clasificacion propuesta por Lukes y Collins (1974). Se incluye a esta entidad dentro del grupo de linfomas de tipo histiocitario. En 1977.Pinol Aguade incorpora a esta reticulosis dentro de los procesos linfoproliferativas de histiocitos, ubicando al Crosti en el subgrupo correspondiente al de linfomas histiocitarios localizados. El interes de la comunicacion es hacer un aporte a la escasa casuistica existente
