A disposable articulated spacing device for use as a temporary joint prosthesis includes a first member secured during an implantation procedure to a first articulation end and a separate and independent second member secured separately during the implantation procedure to the other articulation end, both members being pre-formed and made entirely of biological compatible and porous material suitable to be added with pharmaceutical and therapeutical products. The pre-formed members are reciprocally coupled in an articulated manner to maintain a suitable joint space and at least a partial articulation for the time necessary to perform the further implantation of a joint prosthesis.
