Abstract: A wrist endoprosthesis (2) for functional replacement of the human wrist, containing a radius component (4) that has a shaft (10) for anchoring in the radius, a head (12), and a first joint surface (16), which is implemented on a distal head face (14), and a carpal component (6) that has a proximal carpal face (22), a distal carpal face (20) and a second joint surface (24) which is formed on the proximal carpal face (22) and interacts with the first joint surface (169) of the radius component (4), characterized in that the carpal component (6) is substantially trough-shaped, in order to at least partially surround the carpal bones. Also, a wrist endoprosthesis (2) that has anti-luxation protection (8), a method for producing wrist endoprostheses (2) and a computer program product.
