Abstract

In the present work, an ideal implant was designed to reduce most distal radius fractures. This implant, which is placed with a RAFI technique by a flying approach, allows managing the interfragmentary separation according to the convenience and experience of the hand specialist. First, it was necessary to study the clinical case, including the causes and sequelae and the techniques used to stabilize this type of fracture. In turn, with the help of programs such as ScanIP it was possible to parameterize the study area and create a distal radius biomodel. With this base, the components that the board should contain were designed to create compression between fragments. A radius dorsal fracture with an angle of 30° was simulated and pins corresponding to the holes where the screws of 3.5 mm and 2.4 mm were placed. The implant was analyzed by simulating a radial dorsal fracture in the biomodel in four different types of postoperative load recommended by clinical studies and in optimal and exaggerated positions, this in order to know the numerical - experimental behavior of the plate subjected to different biomechanical conditions. The results and clinical evaluation showed that the proposed implant is suitable for stabilizing radio fractures using the RAFI technique.
