1. A method of manufacturing a prosthesis for a fractured long bone of a patient, the method comprising the steps of:
A) providing data representative of the fractured long bone of the patient, the fractured long bone comprising epiphyseal fragments, each epiphyseal fragment being:
either a tuberosity fragment, secured to a muscle of the patient, the muscle being attached to the tuberosity fragment by means of a tendon of the muscle, or
an articular fragment, being part of a joint of the patient, for articulating the long bone with an auxiliary bone of the patient;
B) based on the data provided at step A), designing the prosthesis specifically to the patient, the prosthesis comprising a stem part configured for securing the epiphyseal fragments to the stem part, step B) comprising:
a sub-step of choosing, specifically to the patient, respective securing positions of the epiphyseal fragments relative to each other, representative of how the epiphyseal fragments are planned to be positioned relative to each other when secured to the stem part, the securing positions being chosen so that a respective patient-specific mechanical stress is applied onto each epiphyseal fragment by at least one of the other epiphyseal fragments by securing the epiphyseal fragments to the respective chosen securing positions of the stem part, and
a sub-step of designing the stem part so that the stem part is configured for securing the epiphyseal fragments at the respective chosen securing positions; and
C) manufacturing the prosthesis including the stem part designed at step B).
