In the male patient, the lesion was located in the middle of the sternum with involvement of the fourth rib, and was diagnosed as bone fibrous dysplasia based on postoperative pathology (Supplementary Table S1, Supplementary Figure S1). Both patients underwent preoperative chest 3-dimention computed tomography (slice thick 1 mm, 120 kV, 346 mA, FOV 500 mm) (Figure 1).
Surgical procedure of sternal tumour resection and reconstruction. (A-F) The female patient. (A) The lesion was exposed and separated. (B-C) Fabrication of sternal prosthesis by 3D-printing. (D-E) A "Sandwich" cement prosthesis is implanted in chest defect region. (F) The resected specimen and bone cement prosthesis were compared with the 3D-printing model. (G-L) The male patient. (G-H) The lesion is exposed and removed. (I) Fabrication of the sternal prosthesis by the 3D-printing mould. (J-K) A "Sandwich" cement prosthesis is implanted in the chest defect region. (L) The resected specimen and bone cement prosthesis as compared to the 3D-printing model.
