The invention discloses a combined device for preventing and treating osteonecrosis, which comprises a combined part, and a positioning frame is positioned and mounted on the outer surface of the bottom end of the combined part. The combined device with the positioning frame for preventing and treating osteonecrosis is positioned outside a bone needing to be treated through the positioning frame; the fracture position of the bone is rapidly adjusted and positioned through the coarse thread stud, then precise positioning is conducted through the fine thread stud, then precise drilling and tapping are conducted to machine threads, along with rotation of the tapping mold, when the mold reaches a certain position, the mold can coincide with the indication rod, and after coincidence is completed, the thread is machined through the indication rod. The screw rod structure can be matched with a calibration point of a post-installed bionic bone structure, so that the bionic bone structure can be more accurately butted
