摘要：
A method and a device for replacing radioulnar joint are disclosed. The method may include inserting a distal stem into a distal part of the ulna bone, and inserting a proximal stem into the proximal part of the ulna bone. In addition, the method may include inserting a stem insertion part located at a proximal end of a mobile locker into the cylindrical-shaped opening of the proximal stem. The method further includes twisting the mobile locker so that the first semicircle-shaped opening and the second semicircle-shaped opening are aligned such that a spherical cavity is formed between the mobile locker, and inserting a mobile globe into the spherical cavity. The method may also include twisting the mobile locker so that the first semicircle-shaped opening and the second semicircle-shaped opening are misaligned and the mobile globe is secured within the spherical cavity, and securing the mobile locker into a substantially fixed position relative to the proximal stem by tightening one or more of a plurality of screws in a plurality of threaded holes.
