The present invention relates to a compression locking-type bone fixing device and, more specifically, to a compression locking-type bone fixing device comprising: a bone screw comprising a body part, which has threads formed along the outer diameter thereof, and a head part, which has threads formed along the outer diameter thereof； a bone plate having at least one locking hole, which has threads formed along the inner diameter thereof and comprises a loading surface on which a portion of the lower surface of the head part is loaded and a through-hole formed in the center of the loading surface； and a locking nut, which has a first spiral part having threads formed along the inner diameter thereof, and a second spiral part having threads formed along the outer diameter thereof, wherein the first spiral part and the second spiral part of the locking nut are spirally coupled to the head part of the bone screw and the locking hole, respectively. According to the present invention, the head part of the bone screw presses the bone plate so as to allow the bone plate to compress the bone, and the locking nut is simultaneously fastened to the head part of the bone screw and the locking hole of the bone plate, and thus compressing of a cortical screw and fastening of the locking screw can be simultaneously achieved.La présente invention concerne un dispositif de fixation osseuse de type à verrouillage par compression et, plus précisément, un dispositif de fixation osseuse de type à verrouillage par compression comprenant : une vis à os comprenant une partie corps, qui a des filetages formés le long de son diamètre externe, et une partie tête, qui a des filetages formés le long de son diamètre externe ； une plaque osseuse ayant au moins un trou de verrouillage, qui a des filets formés le long de son diamètre interne et comprend une surface de chargement sur laquelle une partie de la surface inférieure de la partie tête est chargée et un trou traversant formé au centre de la
