The Use of Alginate Mass to Obtain Limb Geometry for the Sake of Human and Animal Limb Prosthesis

The aim of this study is a practical analysis of the innovative yet non-invasive use of a method obtaining complex human and animal limb geometry on the basis of human and animal limb with its main goal to develop a personalized prosthesis. The hereby article presents an overview of widely known and used external evaluation methods as well as inner limb stump geometry for the sake of fabrication of upper and lower limb prosthesis. A different approach has been presented to limb geometry modeling which is featured by a great shortening of time with a patient due to the use of alginate mass. Because of a lack of possibilities to get limb stump geometry, in the experiment a healthy human and animal limbs were used. The methodology to get a complex human and animal limb shape, presented in this article, involves in the first place the realization of negative cast with the use of alginate mass and secondly positive cast with the use of plaster. The following stages of work include healthy limb 3D scanning and 3D printing in order to make a real-life model.
