          Abstract

          En las fracturas luxaciones de la región lumbar, dos hechos anatómicos pueden ayudar al paciente a presentar un daño neurológico menor en comparación con los traumatismos en la región cervical o torácica, en primer lugar, la médula espinal en el adulto se extiende solo hasta el nivel del borde inferior de la primera vértebra lumbar, en segundo lugar, el gran tamaño del agujero vertebral en esta región da amplio espacio a las raíces de la cola de caballo, por lo tanto, la lesión nerviosa puede ser mínima en esta región, ya que en esta área se alojan raíces nerviosas con un gran espacio, menor contenido y mayor continente. En este estudio se presenta el caso de un hombre de 48 años de edad, trabajador de la construcción, el cual sufrió caída de una altura aproximada de 15 metros, golpeándose directamente sobre la región lumbar contra una viga, presentó dolor e incapacidad para movilizar las piernas; llevado con urgencia, una hora después del accidente, se analizó clínicamente. Se tomaron radiografías y tomografía, y se diagnosticó como fractura luxación L3-L4 con ASIA B. Intervenido tres horas después del accidente con reducción vía posterior y fijación transpedicular. Una semana después se realizó abordaje anterior. Progreso hacia ASIA C, 24 horas después de la primera cirugía. Tres meses después, paciente funcional con ASIA D y control de esfínteres. El propósito del autor es mostrar los resultados obtenidos mediante una intervención en las primeras horas del traumatismo, la cual ayudó a pasar de una lesión no funcional a una lesión funcional, casi con recuperación total.

          In fracture dislocations of the lumbar region two anatomical facts can help patients preserve neurological damage in comparison less trauma to the cervical or thoracic region. First place in adults, the spinal cord extends only to the level of the lower border of the first lumbar vertebra, second, the vertebral hole large in this region gives ample space to the roots of the cauda equina, so both nerve injury may be minimal in this region because in this area are housed nerve roots with great space, less content and more continent. In this study we present the case of a 48 years old male, construction worker, who suffered a fall from a height of approximately 15 meters beating directly on the lumbar region against a beam, presenting pain and inability to move the legs , brought to the emergency room one hours after the accident, is assessed clinically, take x-rays and CT scan and diagnosed as L3-L4 fracture dislocation with ASIA B. Surgically intervened three hours after the accident with reduction via posterior transpedicular fixation. One week later anterior approach was performed. The patient progressed to ASIA C 24 hours after the first surgery. Three months later, he became a functional patient with ASIA D and control of sphincters. The author’s purpose is to show the results obtained by an intervention in the early hours of the trauma which helped promote a nonfunctional injury to a functional lesion, and almost total recovery.

          Nas fraturas-luxações da região lombar dois fatos anatômicos podem contribuir para o paciente apresentar menos danos neurológicos em comparação aos traumatismos na cervical ou torácica. Em primeiro lugar, a medula espinhal no adulto se estende apenas até o nível da borda inferior da primeira vértebra lombar, em segundo lugar, o grande buraco vertebral nesta região dá amplo espaço para as raízes da cauda equina nesta região vertebral dá amplo espaço para as raízes da cauda equina, portanto, a lesão do nervo, pode ser mínima nesta região porque nesta área raízes nervosas são acomodados um grande espaço, com menos conteúdo e mais continente. Neste estudo, apresentamos o caso de um trabalhador da construção civil masculino, 48 anos de idade, que sofreu queda de uma altura de aproximadamente 15 metros, batendo diretamente na parte inferior das costas contra uma viga, apresentando dor e incapacidade de mover as pernas, levado a emergência uma hora após o acidente, para avaliação clinica. De acordo com as radiografias e tomografias, foi diagnosticado como fratura-luxação L3-L4 com ASIA B. Três horas após o acidente, foi realizada redução e abordagem transpedicular posterior. Uma semana depois, ela se submeteu a abordagem anterior. Progrediu para a Ásia C primeiras 24 horas após a cirurgia. Três meses após o paciente funcional com ASIA D e controle do esfíncter. O objetivo do autor é mostrar os resultados obtidos por uma intervenção nas primeiras horas do trauma que ajudaram a favorecer a evolução de uma lesão não-funcional a uma lesão funcional, a recuperação quase completa.

          Clinical spinal instability and low back pain.

          Clinical instability is an important cause of low back pain. Although there is some controversy concerning its definition, it is most widely believed that the loss of normal pattern of spinal motion causes pain and/or neurologic dysfunction. The stabilizing system of the spine may be divided into three subsystems: (1) the spinal column; (2) the spinal muscles; and (3) the neural control unit. A large number of biomechanical studies of the spinal column have provided insight into the role of the various components of the spinal column in providing spinal stability. The neutral zone was found to be a more sensitive parameter than the range of motion in documenting the effects of mechanical destabilization of the spine caused by injury and restabilization of the spine by osteophyle formation, fusion or muscle stabilization. Clinical studies indicate that the application of an external fixator to the painful segment of the spine can significantly reduce the pain. Results of an in vitro simulation of the study found that it was most probably the decrease in the neutral zone, which was responsible for pain reduction. A hypothesis relating the neutral zone to pain has been presented. The spinal muscles provide significant stability to the spine as shown by both in vitro experiments and mathematical models. Concerning the role of neuromuscular control system, increased body sway has been found in patients with low back pain, indicating a less efficient muscle control system with decreased ability to provide the needed spinal stability.

            Classification of thoracolumbar fractures and dislocations.

            M. Aebi (2010)
            A classification of injuries is necessary in order to develop a common language for treatment indications and outcomes. Several classification systems have been proposed, the most frequently used is the Denis classification. The problem of this classification system is that it is based on an assumption, which is anatomically unidentifiable: the so-called middle column. For this reason, few years ago, a group of spine surgeons has developed a new classification system, which is based on the severity of the injury. The severity is defined by the pathomorphological findings, the prognosis in terms of healing and potential of neurological damage. This classification is based on three major groups: A = isolated anterior column injuries by axial compression, B = disruption of the posterior ligament complex by distraction posteriorly, and group C = corresponding to group B but with rotation. There is an increasing severity from A to C, and within each group, the severity usually increases within the subgroups from .1, .2, .3. All these pathomorphologies are supported by a mechanism of injury, which is responsible for the extent of the injury. The type of injury with its groups and subgroups is able to suggest the treatment modality.

              Traumatic Posterior L4–L5 Fracture Dislocation of the Lumbar Spine: A Case Report

              Study Design Case report. Objective The diagnosis and surgical management of a patient with traumatic bilateral posterior dislocation of L4–L5 is presented with a thorough review of the existing literature. Summary of Background Data Traumatic dislocation of L4–L5 has been reported in the English literature in only five cases; of these, only two were retrolisthesis. Methods A 20-year-old patient was involved in a high-energy vehicular accident and presented with back pain and inability to ambulate. Neurological assessment showed motor strength grade 2/5 in the proximal lower-extremity muscle groups (L1–L3 myotomes) and 0/5 strength distally (L4–S1 myotomes); in addition, incontinence of sphincters was found. X-rays and computed tomography (CT) scan revealed a three-column ligamentous injury with posterior fracture-dislocation of the L4 vertebral body with complete posterior displacement of L4 to L5 vertebral body. The patient underwent posterior approach with reduction, transpedicular fixation, and posterolateral fusion with autologous bone graft. Results At 1-year follow-up, the patient had recovered muscular strength in proximal lower-extremities muscle groups, sphincter function had fully recovered, and he was able to ambulate with crutches. There was no recovery of distal extremity sensorimotor function. Plain radiograph and CT scan showed good alignment and progressive maturation of his fusion procedure. Conclusion Traumatic retrolisthesis of L4–L5 is a high-energy unstable fracture; reduction of the dislocation is challenging because of the heavy forces acting in the lower lumbar spine. Instrumented fusion restores alignment and maintains segmental stability.
