Orthopedics and Rehabilitation are two disciplines related to technological change that generate a high demand and a growing volume of activity in developed countries. The design and manufacture of Orthopedic Product has recently undergone great development as it benefits from advances in Industrial Design and new Advanced Manufacturing techniques based on Rapid Prototyping and Additive Manufacturing. The Industrial Design applied to the Orthopedic Product offers to this sector great possibilities of development in the design and manufacture of the splints or orthosis required, but its real implementation requires increasing the provided advantages to those manufactured by traditional methods.The aim of this paper is to invest qualities that improve the chain value of the obtained orthoses by Advanced Manufacturing methods compared to traditional methods, in order to consolidate the expected demand. For this, in addition to ensuring these devices the health function that is required, it is proposed to incorporate the Design Aesthetics as an emotional differentiating element that directly affects the psychology of the injured person to avoid the lack of self-esteem and integration that causes an injury or a morphological alteration.

The Lumbo-Sacral Spine is a structure of the spine that supports one of the greatest burdens of the human body. It constitutes a biomechanical unit and is formed by 5 lumbar vertebrae distributed in such a way that each supports a weight. The Lumbo-Sacral Spine distributes a load and acts as a shock absorber for the spine thanks to its flexibility.The knowledge of the morphology of this spinal structure and its articulation with the first sacral vertebra is fundamental to determine the biomechanical behavior of the entire spinal column. Furthermore, it allows the study of its type of support, its stability and degree of cushioning, its mobility and, in short, all its cinematic and dynamic characteristics.
