RESUMO

INTRODUCTION: Multiple strategies have been developed looking for upgrading the consolidation rate of spine arthrodesis with autolog bone graft, but no evidence exists that adhesion with Collagen type 1 and polyvinylpyrrolidone (FibroquelMR) have application on this field. OBJECTIVE: Determine if collagen type 1 + Polyvinylpyrrolidone are effective as bone enhancer in posterolateral arthrodesis on rabbits. METHOD: Posterolateral arthrodesis in 15 New Zealand rabbits on level L5-L6 using autolog bone graft in left side (control group) and autolog bone graft + 1 ml FibroquelMR (study group) in right side of arthrodesis. Euthanasia and block resection of lumbar segment eight weeks post surgery. Radiographic analysis, manual exploration and light microscopy of fussed segments. RESULTS: Radiographic consolidation was observed in 80% in control group and 95% in study group, interleaved trabecular pattern with bone continuity and normal characteristics in 12 left sides and 14 right sides. CONCLUSION: Collagen type 1 and polyvinylpyrrolidone use is likely to have positive effect in bone consolidation process, therefore it can be recommended to use it as a bone enhancer.


INTRODUCCIÓN: Existen diversas estrategias para aumentar la tasa de consolidación de la artrodesis de columna en presencia de injerto óseo autólogo, sin aún comprobar si la adhesión de Colágena tipo I y polivinilpirrolidona (FibroquelMR) tienen aplicaciones en este campo. OBJETIVO: Determinar la efectividad de la colágena tipo I con polivinilpirrolidona como potenciador óseo en artrodesis posterolateral de conejos. MÉTODOS: Artrodesis posterolateral en 15 conejos de Nueva Zelanda L5-L6 colocando injerto autólogo del lado izquierdo (Control) e injerto autólogo + 1 ml FibroquelMR (Estudio) en el lado derecho de la artrodesis. Eutanasia con resección en bloque del segmento lumbar a las ocho semanas del postoperatorio. Análisis radiográfico, palpación manual y por microscopia de luz de los segmentos fusionados. RESULTADOS: Se observó consolidación radiográfica en 80% en grupo control y 93% en el estudio, continuidad ósea con patrón trabecular intercalado y hueso de características normales en 12 del lado izquierdo y 14 en el lado derecho. CONCLUSIONES: La utilización de Colágena tipo I y polivinilpirrolidona puede tener efectos positivos en el proceso de consolidación ósea por lo que se puede recomendar su utilización como reforzador óseo.

RESUMO

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.


Resumen: 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.

RESUMO

STUDY DESIGN: Retrospective study. OBJECTIVES: To evaluate the demographic and clinical characteristics of patients diagnosed with spinal cord injury (SCI) admitted to a single center. SETTING: Single center study, México. METHODS: This study reviewed 433 patients with SCI. Data were extracted from medical records and retrospectively reviewed. RESULTS: A total of 433 patients with a diagnosis of SCI were included in the analysis. Of these, 346 (79.9%) had traumatic SCI (TSCI) and 87 (20.1%) had non-traumatic SCI (NTSCI). The principal causes of traumatic TSCI were motor vehicle accidents in 150 patients (43.4%), falls in 107 patients (30.9%) and a result of firearms in 58 patients (16.8%). Tumoral cord compression was the main cause of NTSCI in 50 patients (57.4%), followed by degenerative disease-causing myelopathy in 17 patients (19.5%). The proportion of patients affected with NTSCI was significantly lower, 29.9 vs 79.1% (P=0.0001), the age of patients was higher 53.9 vs 37.8 (P<0.002) and SCI was less severe, AIS D 41.33 vs 9.5% (P=0.0001) compared with the TSCI group. CONCLUSIONS: The demographic profiles of patients with TSCI and NTSCI differ in terms of proportion of total SCIs, patient age, male:female ratio and incomplete vs complete injury. The most common etiology of TSCI was motor vehicle accidents (43.4%), and neurological lesions were complete in 62.7% of patients. The most common etiology of NTSCI was tumoral spinal lesions (57.4%), and lesions were incomplete in 75.8% of patients.

RESUMO

La escoliosis del adulto es una deformidad rotacional compleja tridimensional de la columna, resultado de la degeneración progresiva de los elementos vertebrales en la edad madura, en una columna previamente recta; con un ángulo de Cobb mayor de 10º en el plano coronal, que además altera los planos sagital y axial. Se origina de una enfermedad degenerativa, asimétrica del disco y las facetas articulares, creando cargas asimétricas y posteriormente deformidad. El síntoma principal es dolor axial, radicular y déficit neurológico. El tratamiento conservador incluye fármacos y terapia física. Las infiltraciones epidurales y facetarias para bloqueo selectivo de raíces nerviosas mejora el dolor a corto plazo. El tratamiento quirúrgico se reserva para pacientes con dolor intratable, radiculopatía y/o déficit neurológico. No existe un consenso para las indicaciones quirúrgicas, sin embargo, se debe tener un entendimiento claro de los síntomas y signos clínicos. La meta de la cirugía es la descompresión de elementos neurales con restauración, modificación de la deformidad en forma tridimensional y estabilización del balance coronal y sagital.


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 10º 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.

RESUMO

BACKGROUND: Ligamentoplasty is a dynamic stabilization method used to treat lumbar stenosis and resect lumbar herniated discs with good results. The objective of this paper is to report preliminary results of the utility of ligamentoplasty to prevent adjacent segment disease above the arthrodesis. MATERIAL AND METHODS: Two groups of patients with degenerative lumbar spondylolisthesis who underwent circumferential arthrodesis. In 23 patients a dynamic stabilization system was placed in the segment above (group L), while this system was not used in 35 patients (group S). Degeneration and disease of the segment above were assessed. The statistical analysis was done with the SPSS 15.0 software. RESULTS: At the one-year follow-up, the incidence rate of adjacent segment degeneration was 11% for group L and 0% for group S; at the two-year follow-up it was 13% in both groups; at three years, 0% for group L and 19% for group S; at four years, 25% for group L and 0% for group S. At five years, 50% for group L and 0% for group S. Clinically significant radiculopathy occurred in two patients five years after surgery, one of whom also had adjacent segment disease. CONCLUSIONS: Based on the follow-up, at this moment it is not possible to show the utility of dynamic stabilization through ligamentoplasty to avoid adjacent segment disease above the arthrodesis.

RESUMO

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.
