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

Area of Science:

• Thoracic surgery
• Biomaterials engineering
• Oncology

Background:

• Radical resection is standard for primary malignant sternal tumors, necessitating reconstruction for respiratory mechanics, mediastinal protection, and aesthetics.
• Current methods, including titanium implants, have limitations such as poor tissue integration and interference with imaging and radiotherapy.
• Sternal defects require robust reconstruction to restore function and appearance.

Observation:

• A case of sternal reconstruction using a 3D custom-made carbon-fiber prosthesis after extensive resection of a sternal synovial sarcoma is detailed.
• The carbon-fiber material's microporous surface promotes tissue ingrowth.
• Its low density (1.5 g/cm³ ) avoids X-ray blockage, mitigating adverse effects on postoperative imaging and radiotherapy.

Findings:

• The 3D custom-made carbon-fiber prosthesis provided a perfect fit for the thoracic defect.
• Chest wall reconstruction remained stable for over 24 months post-surgery.

Implications:

• 3D custom-made carbon-fiber prostheses represent a promising alternative to metal implants for sternal reconstruction.
• This material offers enhanced biocompatibility and improved compatibility with medical imaging and radiation therapy.
