Se realizaron diseños en CAD de diferentes prototipos, donde se analizan las propiedades mecánicas en el alma del dispositivo, así como en las roscas distal y proximal de los implantes macho y hembra. Asimismo, se obtuvieron modelos 3D de huesos de un infante afectado con OI para realizar simulaciones mediante elemento finito de la interacción entre el hueso y el dispositivo intramedular. Los resultados muestran que los prototipos propuestos disminuyen la deformación del dispositivo, así como el aumento en la rigidez de la relación hueso-prótesis. Asimismo, las roscas generaron un menor esfuerzo en la unión con el hueso, lo que prevé un menor daño al tejido óseo. El trabajo se limitó al análisis numérico del rediseño de implantes telescópicos intramedulares para afectados con OI. Concluyendo que la geometría semicircular 3/4 de caña, otorga un óptimo resultado en las pruebas realizadas, al tiempo que las roscas ACME proveen una mejor sujeción en las epífisis distal y proximal de los huesos largos.]]></p></abstract>
<abstract abstract-type="short" xml:lang="en"><p><![CDATA[Abstract In this work we propose the analysis of different geometries for an intramedullary device, which help to reduce and avoid the migration, deformation and rupture of the implant in bone tissue affected with Osteogenesis Imperfecta (OI). Designs of different prototypes were made in CAD, where the mechanical properties in the device's soul are analyzed, as well as in the distal and proximal threads of the male and female implants. Likewise, 3D bone models of an affected infant with OI were obtained to perform finite element simulations of the interaction between the bone and the intramedullary device. The results show that the prototypes proposed decrease the strain of the device, as well as the increase in the stiffnes of the bone-prosthesis relationship. Also, the threads generated less stress in the union with the bone, which provides less damage to the bone tissue. The work was limited to the numerical analysis of the redesign of intramedullary telescopic implants for patients with OI. Concluding that the semicircular geometry 3/4 of cane, gives an optimal result in the tests carried out, while the ACME threads provide a better subjection in the distal and proximal epiphyses of the long bones.]]></p></abstract>
