Revisión sistemática de las aplicaciones y límites de la impresión 3D en la cirugía de raquis / Systematic review of the utility and limits of 3D printing in spine surgery

Objetivo: El objetivo principal de este estudio ha sido demostrar por qué la impresión aditiva permite hacer más visibles y entendibles los procesos patológicos quirúrgicos complejos que afectan al raquis, aumentando la precisión, la seguridad y la fiabilidad del procedimiento quirúrgico.MetodologíaSe realizó una revisión sistemática de los trabajos publicados en los últimos 10 años, sobre la cirugía de raquis asistida por impresión 3D, de acuerdo con la declaración PRISMA 2020. Con las palabras clave «printing 3D» y «spine surgery» se hicieron búsquedas en las bases de datos Pubmed, Embase, Cochrane Database of Systematic Reviews, Google Scholar y Opengrey, que se completó con la búsqueda manual a través de la lista de referencias bibliográficas de los artículos que fueron seleccionados siguiendo los criterios de inclusión y exclusión definidos.ResultadosDel análisis de los 38 estudios seleccionados resultó que la impresión 3D es útil en la planificación quirúrgica, en la enseñanza médica, en la relación médico-paciente, así como en el diseño de plantillas de navegación e implantes de raquis y, en investigación, ofreciendo un magnífico apoyo al proceder quirúrgico.ConclusionesEl uso de biomodelos impresos de forma tridimensional permite: hacer más visibles y entendibles los procesos patológicos quirúrgicos complejos que afectan al raquis; aumentar la exactitud, precisión y seguridad del procedimiento quirúrgico; y abrir la posibilidad de poner en práctica tratamientos personalizados, fundamentalmente en la cirugía tumoral.

Objective: The main objective of this study has been to demonstrate why additive printing allows to make complex surgical pathological processes that affect the spine more visible and understandable, increasing precision, safety and reliability of the surgical procedure.MethodsA systematic review of the articles published in the last 10 years on 3D printing-assisted spinal surgery was carried out, in accordance with PRISMA 2020 declaration. Keywords «3D printing» and «spine surgery» were searched in Pubmed, Embase, Cochrane Database of Systematic Reviews, Google Scholar and Opengrey databases, which was completed with a manual search through the list of bibliographic references of the articles that were selected following the defined inclusion and exclusion criteria.ResultsFrom the analysis of the 38 selected studies, it results that 3D printing is useful in surgical planning, medical teaching, doctor–patient relationship, design of navigation templates and spinal implants, and research, optimizing the surgical process by focusing on the patient, offering magnificent support during the surgical procedure.ConclusionsThe use of three-dimensional printing biomodels allows: making complex surgical pathological processes that affect the spine more visible and understandable; increase the accuracy, precision and safety of the surgical procedure, and open up the possibility of implementing personalized treatments, mainly in tumor surgery.

Hipotensión intracraneal secundaria a fístula espinal espontánea de líquido cefalorraquídeo: Presentación de tres casos / Intracranial hypotension secondary to spontaneous spinal cerebrospinal fluid fistula: Three case reports

El síndrome de hipotensión intracraneal espontánea (HIE) es una dolencia poco frecuente. El síntoma principal es la cefalea ortostática, si bien pueden aparecer otras manifestaciones como síntomas vegetativos, meningismo o déficits neurológicos focales. La causa más frecuente es una fístula de líquido cefalorraquídeo, generalmente traumática. Las fístulas de líquido cefalorraquídeo espontáneas son poco comunes y se relacionan con la presencia de quistes/divertículos meníngeos o en el contexto de enfermedades del tejido conectivo. El diagnóstico se basa en las pruebas de imagen, tanto para detectar complicaciones intracraneales, como los hematomas subdurales bilaterales y para localizar el punto de fuga a nivel intracraneal o espinal. El tratamiento de la HIE suele ser conservador mediante reposo postural, cafeína y analgésicos. La inyección de un parche hemático epidural es una opción válida cuando persisten los síntomas. La cirugía está indicada en casos refractarios o cuando existe un defecto anatómico evidente y accesible. En el presente artículo se describen tres casos clínicos con síndrome de hipotensión intracraneal secundarios a una fístula de líquido cefalorraquídeo espontánea a nivel espinal (AU)

Spontaneous intracranial hypotension syndrome (SIH) is a rare condition. The main symptom is orthostatic headache, although other symptoms such as vegetative symptoms, meningism, or focal neurological deficits may appear. The most common cause is a cerebrospinal fluid leak, usually traumatic. Spontaneous cerebrospinal fluid leaks are rare and associated with the presence of meningeal cysts / diverticula or in the setting of connective tissue diseases. The diagnosis is based on imaging tests, both to detect intracranial complications and bilateral subdural hematomas and to locate the leak point at the intracranial or spinal level. The treatment of SIH is usually conservative: bed rest, caffeine and analgesics. Epidural blood patch is a good option when symptoms persist. Surgery is indicated in refractory cases or when there is an evident and accessible anatomic defect. This article describes three clinical cases with intracranial hypotension syndrome secondary to a spontaneous spinal cerebrospinal fluid leak (AU)
