Lumbar degenerative spondylolisthesis is the result of the progression from degenerative changes in the intervertebral disc and facet joints that lead to destabilizing one or more vertebral segments. It is characterized by the anterior sliding of the vertebral body secondary to the sagittalization of the facet joints. Wiltse, Newman, and Macnab classified it as type III. It is a pathology typical of elderly patients that predominate in women with a ratio of 5:1 compared to men; the most affected segment is L4-L5, the listhesis rarely exceeds 30% slip. It may or may not generate clinical manifestations, and the severity of these does not always correlate with the degree of sliding. The cardinal symptom is lumbar pain with or without radicular pain. Neurogenic claudication occurs in 75% of patients; it is caused by blood hypoperfusion secondary to the compression of the nerve roots, manifesting as pain in the lower limbs with variable walking distances. For the diagnosis of degenerative spondylolisthesis, comprehensive evaluation with static, dynamic radiographic studies in a standing position and magnetic resonance imaging are essential. The conservative treatment is the first-line therapy; it includes analgesics, anti-inflammatories, physiotherapy.

RESUMEN. Introducción: el análisis bi bliométrico es una forma útil de evaluar el pasado, el pre sente y el futuro de las publicaciones relacionadas con un área determinada de forma cualitativa y cuantitativa. Objetivo: determinar las características de la productividad nacional en investigación escrita por autores mexicanos en el campo de cirugía de columna a través del tiempo. Material y métodos: se realizó una búsqueda exhaustiva en línea en Octubre de 2021 utilizando la base de datos Scopus desarrollada por Elsevier. La información de las publicaciones recolectadas fue la siguiente: año, título, acceso, idioma, revista, tipo de artículo, tema, objetivo, citas, autores e instituciones de afiliación. Resultados: se identificó un total de 404 publicaciones entre 1973 y 2021. El número de publicaciones entre la década 1991-2000 y 2011-2021 incrementó 68.28 veces. La mayoría de las publicaciones se realizaron en instituciones de la región centro-sur de México (66.16%), seguida de la región occidente (15.03%) y noreste (8.27%). El índice H más alto encontrado fue de revistas de origen estadounidense (102). La mayor parte de las publicaciones se realizó en la revista ABSTRACT. Introduction: bibliometric analysis is a useful way of assessing the past, present and future publications related to a given area in a qualitative and quantitative way. Objective: to determine characteristics of national authors productivity in the field of spine surgery research across the time. Material and methods: an online research was performed using the Elsevier´s database Scopus in October, 2021. All studies were assessed for the following parameters: year, title, access, language, journal, type of article, focus of research, objective of research, cites, authors and institutions. Results: a total of 404 publications were identified between 1973 and 2021. Between 1991-2000 decade to 2011-2021 decade the number of published articles tended to increase by 68.28 times. The largest number of articles was from South-Central Region (66.16%), followed by Western (15.03%) and Northwest (8.27%). The highest h-index was found for USA journals (102). The highest number of articles was published in Coluna/Columna (15.53%), followed by Cirugía y Cirujanos (10.52%) and Acta Ortopédica Mexicana (8.52%).
