Abstract: Disclosed is an orthopedic apparatus for pectus excavatum, the orthopedic apparatus including: a primary pectus bar inserted behind a concave sternum for pectus deformity repair; a secondary pectus bar inserted in front of the sternum to be in parallel with the primary pectus bar; and a locking member provided at a junction between the primary pectus bar and the secondary pectus bar to lock the primary pectus bar relative to the secondary pectus bar. According to the present invention, the primary pectus bar inserted behind the concave sternum is fixed through the secondary pectus bar that is inserted in front of the sternum, whereby it is possible to prevent the primary pectus bar from rotating or moving during the long period of correction, thereby accurately performing sternum repair.
