While less common than pectus excavatum, pectus carinatum is also a chest wall deformity affecting males in higher proportion than women. Patient requests for a solution of this disease occur especially during the growth spurt of puberty when this malformation becomes more obvious and difficult to conceal. Those people suffering from pectus carinatum are very likely subject to behavioral changes and negative personality impacts. By compressing the protruding anterior region of the chest wall we achieve correction of the chest contour and simultaneous lateral expansion of the depressed costochondral arches. This original technique and the procedure to apply it fit within the category of minimally invasive surgery. The compression system acts in a way similar to that of orthodontic braces. Two rectangular fixation plates are fixed to the compression strut with screws. The plates have threaded holes along a groove in the central portion, and two holes at both ends used to attach them to the ribs by means of steel wire suture. The compression strut has to be modified into a convex shape to adapt it to the particular characteristics of the patient’s malformation. This molding is done using benders designed as part of the procedure.
