Disclosed is a connecting prosthesis for bone defects, relating to the medical field. The connecting prosthesis comprises a fixed prosthesis (1) and an adjusting prosthesis (2). A connecting component (4) is arranged at one end of the fixed prosthesis (1), and a first medullary canal stem (3) is arranged at the other end. The first medullary canal stem (3) is integrally formed with the fixed prosthesis (1). A blind hole (11) is arranged in the connecting component (4). A first locating hole (7) is arranged in the blind hole (11). A first locking screw (8) is arranged at the first locating hole (7). One end of the adjusting prosthesis (2) is arranged in the blind hole (11) and detachably connected to the blind hole (11) through the first locking screw (8). A second medullary canal stem (5) is arranged at the other end of the adjusting prosthesis. The second medullary canal stem (5) is integrally formed with the adjusting prosthesis (2). An adjuster (6) is arranged on the adjusting prosthesis (2). The adjuster (6) can slide on the adjusting prosthesis (2). A second locating hole (9) is arranged in the adjuster (6). A second locking screw (10) is arranged at the second locating hole (9). The adjuster (6) is detachably connected to the adjusting prosthesis (2) through the second locking screw (10). With this technical solution, according to actual conditions, by means of appropriate regulating, the prosthesis can be mounted to have a better mechanical performance and support effect, and the functionality can be restored earlier.La présente invention concerne une prothèse de liaison pour des défauts osseux, liée au domaine médical.
