EN Reverse engineering and rapid prototyping found a wide range of applications in the area of orthopaedics. The development of these technologies enabled the manufacturing of orthoses and prostheses adapted individually to the patient's anatomy. Additionally, contemporary computer techniques allow to produce orthoses with various designs which help to keep the hygiene of limb, facilitate access to injury, and ensure ventilation of skin. The aim of this study was to develop the concept of individuated orthosis dedicated to the upper limb with pattern structure and removable elbow part to speed up the rehabilitation process. The designed orthosis consisted of 6 interconnected components. Additionally, instead of the standard separation edge along a straight line, a spiral curve was used. The proposed 3D pattern structure reduced mass by 31.3% compared to a full-volume component. The designed model of the orthopaedic appliance was subjected to strength analysis using the finite element method (FEM). Simulation results, in the form of stress and displacement distributions, were presented and discussed. Then, a physical model of the developed orthosis made using rapid prototyping technology (3D printing) was presented.
