Resumen

El objetivo de una sutura tendinosa es que sea lo suficientemente resistente para permitir una movilidad activa precoz. Para ello, los cirujanos deben comprender las características biomecánicas de las suturas tendinosas. El objetivo de este artículo es recoger los aspectos fundamentales de los estudios biomecánicos, así como los principales factores que influyen en la resistencia de una sutura, tanto en tenorrafias primarias como en el caso de injertos y transferencias. Estudios in vitro o in vivo, con tracción lineal o curvilínea, cíclicos o de tracción única, son algunos de los factores que hemos de tener en cuenta a la hora de analizar un estudio sobre suturas tendinosas, así como conocer los principales parámetros físicos que analizan. Así mismo el material, el diámetro, la configuración, el número de hebras, el tipo de agarre al tendón, la tensión de la sutura, el tipo de nudo y la configuración de la sutura epitendinosa son los principales factores que influyen en la resistencia de las suturas primaria. En el caso de los injertos y transferencias, el número de entrelazaos y el tipo de puntos utilizados, son los principales aspectos que influyen en la sutura tipo Pulvertaft y sus alternativas.

Abstract

The goal of a tendon suture is to be strong enough to allow active early mobility. Surgeons must understand the biomechanical characteristics of tendon sutures. The aim of this article is to collect the fundamental aspects of biomechanical studies as well as the main factors that influence the strength of a tendon suture, both in primary tenorrhaphies and in tendon grafts and transfers. Studies in vitro or in vivo, with linear or curvilinear traction, with cyclic or single traction, are some of the factors that we have to take into account when analyzing a study of tendon suture, as well as knowing the main physical parameters. Likewise, the material, the diameter, the configuration, the number of strands, the type of grip to the tendon, the tension of the suture, the knot and the configuration of the epithendinous suture are the main factors that influence the resistance of the sutures. In the case of grafts and transfers, the number of weaves and the type of stitch are the main aspects that influence in the Pulvertaft weave suture and its alternatives.
