Resumen
CARRERA-PINZON, Andrés Felipe et al. Development of an easy-to-assemble external fixation system for bone transport. Dyna rev.fac.nac.minas [online]. 2019, vol.86, n.208, pp.53-59. ISSN 0012-7353. https://doi.org/10.15446/dyna.v86n208.68012.
We developed a monolateral external fixation system for bone lengthening that is easier to assemble than commercial systems. In this system, the clamps can be laterally assembled to the rail in contrast to the commercial systems in which the clamps can only be assembled from the ends. The system is formed by clamps, screws, and a rail. The rail is composed of two carbon fiber circular rods of ½” diameter and 42 cm length. The clamps can slide with respect to the rail to allow bone distraction or may be fixed to the rail by using a wedge and a screw. The prototype was mechanically evaluated under the ASTM F1541 standard. The stiffness in axial loading, medio-lateral bending (ML), antero-posterior bending (AP), and flexo-torsional loading were 117 N/mm, 46 N/mm, 8.7 N/mm, and 5.8 N-mm/°, respectively, which are in the range of the stiffness of commercial systems.
