Abstract
Implante superelástico para artrodesis interfalángicas, destinado al alineamiento postural de las falanges corrigiendo deformaciones como por ejemplo dedo en garra o martillo, consistente en una pieza de breve grosor constante, fabricada en material con alto coeficiente de elasticidad, idealmente aleación de titanio y níquel, que conforma dos horquillas, una mayor y otra menor, dispuestas axialmente opuestas a partir de la solidaridad de sus arcos, cuyas ramas presentan en sus extremos distales sendos ensanchamientos en punta de elipse que facilitan su penetración y que en sentido proximal se expanden hacia los laterales configurando escalones posteriores de retención, teniendo los bordes externos de las ramas mayores apéndices de retención en diente de sierra y en la zona de vinculación de los arcos, sendas aletas, de manera tal que, venciendo la posición normal abierta de las pinzas se introducirá el implante en el canal medular del hueso de cada falange, dentro del cual la memoria elástica del material promoverá su expansión para que los apéndices de retención produzcan la retención, en especial en las ramas más largas correspondientes a la falange proximal de la articulación comprometida.Super-elastic implant for interphalangeal arthrodesis, intended for postural alignment of the phalanges, correcting deformations such as a claw or hammer toe, consisting of a piece of short constant thickness, made of material with a high elasticity coefficient, ideally titanium and nickel alloy, which It forms two forks, one larger and one smaller, arranged axially opposite from the solidarity of their arches, whose branches have at their distal ends two widened ellipse points that facilitate their penetration and that extend proximally to the sides, configuring subsequent retention steps, with the outer edges of the branches greater retention appendages in the sawtooth and in the area of connection of the arches, two fins, so that, overcoming the normal open position of the tweezers, the implant will be introduced in the medullary canal of the bone of each phalanx, within which l The elastic memory of the material will promote its expansion so that the retention appendages produce retention, especially in the longer branches corresponding to the proximal phalanx of the compromised joint.
