Three-dimensional custom-made carbon-fiber prosthesis for sternal reconstruction after sarcoma resection

Radical resection is the preferred therapy for primary malignant sternal tumors. Sternal reconstruction is required to guarantee the best preservation of respiratory mechanics, and adequate mediastinal protection and acceptable cosmetic results after extensive tumor resection. A wide variety of methods and materials have been described for sternal reconstruction. Titanium implants are preferred by many surgeons because of their optimal features. However, the smooth surface of the metal prostheses does not facilitate the inward growth of the tissue, and the high density of metal can block the X-ray and cause adverse effects on postoperative imaging and radiotherapy. Therefore, in this article we present a case of sternal reconstruction by means of a three dimensional (3D) custom-made carbon-fiber prosthesis following extensive resection of a sternal synovial sarcoma. The microporous structure on the surface of the carbon fiber composite material facilitates the inward growth of the tissue. Low density (1.5 g/cm³ ) of carbon-fiber implant will not block the X-ray and eliminates the adverse effects caused by metal material of postoperative imaging and radiotherapy. The 3D custom-made carbon-fiber prosthesis matched the thoracic defect perfectly and the chest wall reconstruction was stable for more than 24 months.
