The present invention regards an elbow spacer device, including: at least one ulnar section, including a stem portion extending along a substantially longitudinal axis (x-x) between a proximal end and a distal end； at least one humeral section, including a stem portion extending along a substantially longitudinal axis (y-y) between a proximal end and a distal end, the distal end of the humeral section delimiting an engagement seat with the proximal end of the ulnar section； articulation means between the distal end of the humeral section and the proximal end of the ulnar section, positionable along an axis (z-z) that is orthogonal to the substantially longitudinal axis (y-y) of the humeral section. The proximal end of the ulnar section is engageable in the housing seat.
