Abstract
El nacimiento y desarrollo de la artroplastia discal lumbar ha seguido un proceso más lento y reciente si lo comparamos al de las prótesis de cadera. De la experiencia obtenida de su historia combinada con los implantes de rodilla se han heredado importantes conceptos que se han aplicado a las distintas estrategias de diseño, fijación y tribología. La artroplastia discal lumbar se presenta como alternativa adecuada frente a la artrodesis tradicional. Está avalada por buenos resultados clínicos a corto y medio plazo. La colocación por vía anterior en L4-L5 es especialmente difícil por la anatomía de los grandes vasos y la necesidad de su movilización, hecho que se asocia a complicaciones que pueden ser potencialmente severas, y por este motivo se ha desarrollado el abordaje oblicuo. Justificación, hipótesis y objetivos: A pesar de experimentar un auge en la cirugía de reemplazo discal lo cierto es que la literatura publicada no es numerosa ni definitiva en cuanto a sus conclusiones, en especial respecto a la técnica oblicua para su colocación. La hipótesis de partida es que la prótesis oblicua en L4-L5 permite alcanzar buenos resultados clínicos y radiológicos manteniendo el movimiento, con una relativamente baja tasa de complicaciones. Además, se analiza la influencia independiente de la colocación, peso, género y edad en estos parámetros...
Birth and development of lumbar disc arthroplasty has followed a slow and recent process compared to hip prosthesis. Important concepts have been inherited from the combined experience of hip and knee implants and they have been applied to several strategies in design, fixation and tribology. Lumbar disc arthroplasty stands as a proper alternative to traditional arthrodesis. It is supported by short and mid-term good clinical results. L4-L5 disc arthroplasty through anterior approach is especially difficult due to the anatomy of great vessels and the need of mobilization that encompasses complications that could be potentially severe, being the reason to develop an oblique approach. Justification, hypothesis, purpose: Disc replacement surgery has experienced a rise but literature is scarce and inconclusive, especially regarding oblique implantation technique. Baseline hypothesis is that oblique L4-L5 arthroplasty offers good clinical and radiological results, preserving motion, with a relatively low complications rate. Plus, independent influence of position, weight, gender and age on this parameters was also analyzed...
