Chest wall resection and reconstruction for neoplastic diseases has unique oncologic, structural, and functional challenges. In a young and fit patient with a mediastinal mass and extensive anterior chest wall invasion, purely structural solutions were deemed insufficient. We hereby present a novel three-dimensionally printed patient-specific titanium implant of sternum and ribs. This osteointegrable implant was designed with biomechanical capabilities using a unique "Greek wave" folding pattern. Postoperative dynamic computed tomography showed that the implant allowed for controlled flexing during the respiratory cycle. Three-dimensional printing with biocompatible materials could enable a new generation of chest wall implants strongly focused on functional reconstruction.
胸壁肿瘤性疾病的切除与重建面临着独特的肿瘤学、结构和功能挑战。对于一名年轻且身体状况良好、患有纵隔肿块并伴有广泛前胸壁侵犯的患者，单纯的结构性解决方案被认为是不够的。在此，我们展示一种新型的三维打印定制胸骨和肋骨钛植入物。这种具有骨整合能力的植入物采用独特的“希腊波浪”折叠模式设计，具备生物力学性能。术后动态计算机断层扫描显示，该植入物在呼吸周期中能够实现可控的弯曲。使用生物相容性材料进行三维打印能够催生新一代高度注重功能重建的胸壁植入物。
