Artroplastias primarias de cadera implantadas en Cataluña: ¿qué evidencia clínica respalda a nuestras prótesis? / Primary total hip arthroplasty in Catalonia: What is the clinical evidence that supports our prosthesis?

Introducción: la cumplimentación de registros sobre la implantación de prótesis permite obtener una gran cantidad de datos y extraer conclusiones que redundan en la mejora de la utilización de las mismas. Suecia fue el primer país en implantar un sistema de registro de artroplastias en 1979. Cataluña lo viene haciendo desde el año 2005. El objetivo de nuestro trabajo es analizar la evidencia que respalda a las prótesis implantadas en artroplastias totales de cadera primarias en Cataluña en los últimos 9 años sobre la base del Registro de Artroplastias de Cataluña (RACat). Material y métodos: se realizó una revisión en la literatura de las prótesis (cotilos/vástagos) registrados en el RACat entre los años 2005-2013 en las siguientes bases datos: Orthopaedic Data Evaluation Panel (ODEP), Tripdatabase, Pubmed, Google académico. Se excluyeron aquellas prótesis implantadas en número inferior a 10 unidades (182 cotilos correspondientes a 49 modelos/228 vástagos correspondientes a 63 modelos). Resultados: de los 18.816 cotilos implantados, se analizaron 18.634 (el 99%), correspondientes a 74 modelos diferentes. En 18 modelos (2.527 cotilos) no se encontraron evidencias clínicas que respalden su uso. De los 19.595 vástagos implantados se analizaron 19.367 (el 98,84%), correspondientes a 75 modelos diferentes. En 16 modelos (1.845 vástagos) no se encontraron evidencias clínicas que respalden su uso. En los 56 modelos de cotilos (16.107) y los 59 modelos de vástagos (17.522) restantes las evidencias variaron en función del número de pacientes y los años de seguimiento, predominando los estudios con nivel de evidencia iv. Conclusiones: existe un número significativo de prótesis implantadas evaluadas (13,56% cotilos/9,5% vástagos) en los que no se han encontrado evidencias clínicas. Cabe destacar el alto número de modelos (49 tipos para cotilos/63 tipos para vástagos) con una implantación inferior a 10 unidades que corresponden únicamente al 1% del total. La implantación de registros de artroplastias se revela como una herramienta extremadamente útil al permitirnos analizar y extraer conclusiones para la evaluación y el seguimiento poscomercialización

Introduction: the implementation of National Prostheses Registries allows us to obtain a large amount of data and make conclusions in order to improve the use of them. Sweden was the first country to implement a National Prostheses Registry in 1979. Catalonia has been doing this since 2005. The aim of our study is to analyse the evidence that supports primary total hip replacement in Catalonia in the last 9 years, based on the Arthroplasty Registry of Catalonia (RACat). Material and methods: a review of the literature was carried out of the prosthesis (acetabular cups/stems) reported in the RACat between the period 2005 to 2013 in the following databases: ODEP (Orthopaedic Data Evaluation Panel), TRIP database, PubMed, and Google Scholar. Those prostheses implanted in less than 10 units (182 acetabular components corresponding to 49 models/228 stems corresponding to 63 models) were excluded. Results: a total of 18,634 (99%) implanted acetabular cups were analysed out of a total number of 18,816, corresponding to 74 different models. In 18 models (2527 acetabular cups) no clinical evidence to support its use was found. An analysis was performed on 19,367 (98.84%) out of a total number of 19,595 implanted stems, corresponding to 75 different models. In 16 models (1845 stems) no clinical evidence was found to support their use. Variable evidence was found in the 56 models of acetabular cups (16,107) and 59 models of stems (17,522), most of it corresponding to level iv clinical evidence. Conclusions: there was a significant number implanted prostheses evaluated (13.56% acetabular cups/9.5% stems) for which no clinical evidence was found. The elevated number of models is highlighted (49 types for acetabular cups/63 types for stems) with less than 10 units implanted, which corresponds to only 1% of the total implants. The use of arthroplasty registers is shown to be an extremely helpful tool that allows analyses and conclusions to be made for the follow-up and post-marketing surveillance period

Hipergranulación en heridas crónicas: un problema ocasional pero no infrecuente / Hypergranulation of chronic wounds: an occasional but not infrequent problem

La hipergranulación es un problema ocasional, pero a la vez no infrecuente,con el que se enfrentan muchos clínicos responsables del tratamientode heridas en su práctica diaria. Este fenómeno ocurre en unamplio abanico de heridas que incluyen las incisiones y heridas posquirúrgicas,los estomas (gastrostomías, traqueostomías, etc.) y las heridascrónicas.El objetivo del presente artículo es cuantificar y analizar la evidencia generadaen torno al tema de la hipergranulación en las heridas crónicas, mediantela búsqueda bibliográfica en diversas bases de datos.Tras el análisis y revisión de los diferentes documentos recuperados se evidencia,tanto cuantitativa como cualitativamente hablando, una escasezimportante de investigación en torno a la hipergranulación en heridas crónicas.Esto hace que el problema no se halle lo suficientemente explicado yque no existan evidencias sólidas que justifiquen el uso de un tratamientosobre otro

Hypergranulation is an occasional but no infrequent problem, which many clinicians face in their daily practice. This phenomenon occurs in a variety of wounds that includes post-surgical incisions and wounds, stomas (gastrostomies, tracheotomies.) and chronic wounds.The objective of the present article is to quantify and to analyze the evidence generated around the topic of the hypergranulation in chronic wounds, through the bibliographical search in diverse data bases.After the analysis and revision of the different recovered documents it is demonstrated, both in terms of quantity and quality, an important shortage of investigation around the hypergranulation in chronic wounds. Therefore, the problem is not sufficiently explained and solid evidences do not exist to justify the use of a treatment over another one
