The prosthetic patch was then implanted to cover the chest wall defect. During the operation, the silicone mould was used to produce rigid prostheses consisting of methyl methacrylate and two layers of polypropylene mesh in a “sandwich” fashion. The patient subsequently underwent right upper lobectomy with en bloc resection of the involved chest wall. These models were 3D printed, and a silicone mould was created from them. Based on these data, the program generated digital models of the right 3rd, 4th, and 5th ribs. The patient's age, weight, height, and sex, as well as the number and side of the ribs of interest, were the inputs to the program. Prior to surgical resection, a statistical shape model of human ribs was created and used to synthesise rib models in the software MATLAB (MathWorks, Natick, MA, USA). A 64-year-old male was diagnosed with non-small-cell lung cancer originating in the right upper lobe and invading the lateral aspect of the 3rd, 4th, and 5th ribs. This report presents the first clinical case where patient-specific rib prostheses were created using a computer program and statistical shape model of human ribs. Management of chest wall defects after oncologic resection can be challenging, depending on the size and location of the defect, as well as the method of reconstruction.
