Guidelines for surgical management of posttraumatic pectus excavatum have not been established due to the variable clinical manifestations and limited number of cases. A 34-year-old man who was involved in a truck-mixer vehicle crash 6 months previously complained of a depressed anterior chest wall deformity. The patient had successfully undergone subperichondral resection, sternal osteotomy, and pectus bar insertion placed under the depressed sternum, followed by bar rotation for elevation of the chest wall. This case illustrates that a modified Ravitch procedure, using a pectus bar, may be an alternative for posttraumatic pectus excavatum.
