A temporary spacer device, for an articulation of a human body, comprising

• a first component or femoral component, adapted to be constrained to a first bone or to a femoral bone of a patient, at a joint of the human body;
• a second component or tibial component, adapted to be constrained to a second bone or tibial bone of the patient, at the joint of the human body;
• and
• at least one stem having a proximal end, a distal end, and an elongated body therebetween, said elongated body defining a longitudinal axis,
• wherein one or both of said first component or femoral component and said second component or tibial component comprise at least one housing seat for said proximal end of said at least one stem, so as to allow a change in inclination with respect to said housing seat and/or a rotation of said at least one stem with respect to an insertion axis of said proximal end in said at least one housing seat,
• wherein said elongated body comprises at least one recess containing a filling material, and
• wherein said filling material comprises an acrylic bone cement, or a solid, fluid and/or viscous material adapted to convey and release at least one pharmaceutical or medical substance, and at least one pharmaceutical or medical substance.
