Three-Dimensional Reconstruction of the Sternum: a Novel Approach for Improved Surgical Oncology Outcomes

Sternum plays a crucial role in chest stability and protection of vital organs. Sternal defects after major oncological resection pose significant challenge for reconstructive surgery. Traditional techniques using autologous tissue or synthetic material have limitations in achieving optimal functional and aesthetic outcomes. Three-dimensional (3D) printing technology offers a promising solution for personalized sternal reconstruction. This article presents a series of patient with complex sternal defects who underwent 3D-printed sternum reconstruction.

The article describes the preoperative planning process, surgical technique, and postoperative outcomes after radical resection of primary sternum tumour and reconstruction with 3D titanium implant.

Four patients of primary sternum tumour managed by radical resection and customised 3D implant reconstruction were included. The median age was 33 years with male: female ratio of 3:1. R0 resection was achieved in all, first patient had non porous implant followed three porous implant reconstruction. No patient had postoperative wound or implant related complications. After median follow up of 21 month all patients were alive and disease free.

The 3D printed sternum reconstruction provides a customized, anatomically accurate solution with improved surgical precision and excellent patient satisfaction. Further studies are warranted to evaluate long-term outcomes and cost-effectiveness of this innovative approach.
