The invention relates to a semiconstrained total elbow prosthesis made of TiNi biocompatible shape-memory alloys meant to replace the human elbow joint affected as a consequence of accidents or bone or joint diseases. The prosthesis, as claimed by the invention, has two components: a. an ulnar component (1) which is fixed in the medullary canal of the ulna, and a humeral component (2) which is fixed on the humeral bone canal. The attachment extension of the humeral component (2) on the recess in the transverse end of the ulnar component (1) is carried out by activating the shape-memory properties of the alloy, meaning that the open position is activated at a low temperature of 1...3°, and the closed position is activated at a temperature slightly lower than the temperature of the human body, namely between 30...33°C.
