Design of orthoses and prostheses for the lower limb using 3D printing techniques for veterinary use

Abstract

Orthoses have proven to be an effective option for correcting and addressing mobility issues in damaged joints. However, up until now,their design and manufacturing have primarily focused on human sizes, without sufficient attention to the anatomical and behavioral characteristics specific to pets. This results in devices that do not optimally fit the shape and function of the limbs of dogs and cats.
Given the anatomical variability among canine and feline breeds, as well as body sizes, it is necessary to have orthoses specifically designed for each patient, which could significantly improve outcomes such as pressure distribution, range of motion, comfort, and adherence to use. Therefore, the overall objectives were to design a model of veterinary orthoses and prostheses manufactured using 3D printing and biocompatible materials, allowing for better anatomical fit and improved functionality during rehabilitation, leading to significantly positive results.
The proposed approach would enable the production of customized devices that optimize parameters such as bone pressure distribution, range of motion, and adherence to use during rehabilitation. Demonstrating its viability in dogs and cats represents a significant advancement towards the development of this technology for all animal species.
