The aim of the present work was to explore the feasibility of
different additive manufacturing techniques applied in design, diagnosis and
planning of a locked intramedullary nail used in the diaphyseal femoral
fractures. Using a clinical case study of a femoral diaphysis fracture, a
biomodel was developed to simulate the osseointegration bone-implant. The
biomechanical analysis was performed using the finite element method and
different additive manufacturing techniques were applied, particularly the full
colour printing to obtain the colour levels related to von Mises stresses. The
biomodel and all applied prototyping techniques have proved to be important,
since they allow fast reconstruction of layered prototyping models from point
cloud data with a shape errors control. In surgical procedures these models can
provide practice simulators, procedure guides and models against which to
measure progress by helping health professionals on an accurate and safe
surgical planning.
