Contouring posterior and lateral tibia of javanese people based on X-Rays images

Abstract

Osteosynthesis plates provide a rigid and stable fixation for bone fracture treatment. The bone stability during the fixation period is determined by the conformity between the bone and plate. The plate fits well to the bone if it is designed based on the bone contour. Hence, the contour profile of bone must be determined prior to designing the plate. The aim of this work is to perform a contouring technique for human tibia and then to formulate the results into a mathematical model. Samples were 2D X-rays images of five tibia from Javanese people. The data was well fitted to the Rational Chebyshev equation.
