This project focuses on patients with chest wall tumors who are expected to have a maximum intraoperative anterolateral chest wall defect diameter of 5-10 cm and require chest wall reconstruction with rib implants. It aims to evaluate the efficacy and safety of biodegradable 3D-printed implants in chest wall reconstruction surgery, providing a superior reconstruction strategy for patients with tumor-induced chest wall defects.
