ABSTRACT

Objetivo. Evaluar las diferencias entre dos sistemas de osteo-síntesis intramedular en fracturas de extremo proximal de fémur inestables, observando si la presencia de un tornillo antirrotación mejora el resultado final. Material y método. Se diseña un sistema de valoración funcional individualizada por enfermo. Aplicando este sistema se realiza un estudio retrospectivo valorando la colocación y evolución clínica de dos sistemas de enclavado endomedular (Gamma® y Claufitt®). Se valora la situación funcional del paciente a medio plazo en el área de población de un hospital universitario. Se obtiene una base final de datos con 43 casos de Claufitt® aptos para el estudio. Resultados. La valoración funcional real es un método de evaluación sencillo, reproducible y útil para el seguimiento pormenorizado de los enfermos de modo individual y del mismo modo aplicable a cualquier tipo de intervenciones o protocolos de seguimiento. Aunque los resultados no son estadísticamente significativos, el Claufitt® presenta, respecto al clavo Gamma®, un 10% de mejores resultados. Conclusiones. La valoración funcional y la evolución de cada enfermo en particular pueden ser evaluadas de un modo sencillo mediante la valoración funcional real. Las diferencias entre los dos tipos de sistemas de osteosíntesis intramedular no son objetivables ni técnica ni clínicamente. Los datos obtenidos son acordes con la bibliografía publicada


Purpose. To assess the differences that exist between two intramedullary osteosynthesis systems for the treatment of unstable proximal femoral fractures in an attempt to find out whether the use of an antirotation screw improves the final result. Materials and methods. A retrospective study was carried out to analyze the plcement and clinical evolution of both intramedullary nailing systems (Gamma® y Claufitt®). The patients' medium-term functional status was evaluated and benchmarked against the characteristics of the population served by our University Hospital. A final database was obtained made up of 43 cases of Claufitt® that met the criteria of our study. A functional assessment system was custom designed for each patient. Results. Although the results are not statistically significant, the results obtained with Claufitt® proved to be 10% better than those for the Gamma®, nail. The Real Functional Assessment is a straightforward, reproducible and useful evaluation method to perform an detailed individualized follow-up of our patients that can be applied to any type of procedure or follow-up protocol. Conclusions. The data obtained are in line with that published in the literature. The differences between the two intramedullary osteosynthesis systems cannot be quantified technically or clinically. Each patient's functional status and clinical evolution can be determined easily through the Real Functional Assessment (AU)

ABSTRACT

Las prótesis totales de rodilla constituyen uno de los implantesmás colocados en el ámbito de la ortopedia. El númerode modelos existentes en el mercado es muy elevadoy todos tienen sus características. A pesar de ello podemosagrupar las artroplastias de rodilla por estas caracterísricas,siendo las prótesis de platillo móvil el grupo más novedoso.Revisamos la bibliogrfía más reciente sobre la biomecánicade las prótesis totales de rodilla, englobando aspectos comolos materiales, el polietileno, la fijación, la geometría ola presencia del ligamento cruzado posterior para entenderen profundidad el funcionemiento de una PTR


Total knee prostheses (TKAs) are one of the most frequentimplants we use like orthpaedists. There are a largenumber of models and all of them have their characteristics.Despite of it we can group TKAs in avery few ones inwhich mobile-bearing arthroplasty in the newness. We reviewthe literature about biomechanics of TKAs includingmaterials, UHMWPE, fixation of the prostheses, geometryor presence of the cruciate posterior ligament to really understandarthroplasty working

ABSTRACT

La biomecánica de la rodilla todavía no se conoce exactamente.Diversos patrones se han establecido, pero ningunoha alcanzado el funcionamiento real de la articulación.Revisamos la bibliografía y presentamos la evolucióndel entendimiento del movimiento de la rodilla hasta llegaral modelo de seis grados de libertad en la zona patelofemoraly en la tibiofemoral. Este modelo parece ser el másaproximado a la realidad en cuanto a la cinemática de larodilla


Knee´s biomechanics is not well known yet. A largenumber of patterns has been stablished, but neither ofthem has reached the right articular movement. We reviewthe literature and present the understanding about kneemovement until six grades of freedom model in patello-femoraland tibio-femoral zones. This model seems to be themost approximate to reality in knee kinematics

ABSTRACT

Five cases of elastofibroma dorsi are described. The location of the lesions (bilateral in one case) was typical, in the thoracoscapular region. In the first case the diagnosis was established by biopsy; in the remaining cases the diagnosis was suspected based on clinical and magnetic resonance imaging findings and was confirmed by histopathological study after surgical excision. Although these lesions are benign, histological study is advisable to establish a differential diagnosis with malignant neoplastic processes.
