Modular polycentric prostheses design for hip disarticulation

This summary describes the design and construction of a modular hip prostheses, it has polycentric mechanism with three links that mimic the trajectory of the human hip's geometric center. In presence of one of the lower limbs, the system provides an additional running at all stages at speeds of 6 km/h in an instrument with a weight of 560 gr. The prosthetic system is uniaxial, presenting a two-dimensional displacement in one plane that is, doesn't have patellar movement on orthogonal planes to the motion axis, being unnecessary for this.
