Post-sternotomy mediastinitis (PSM) is a serious complication of median sternotomy. It is associated with a high mortality rate. Evidence based management recommends debridement followed by closure with vascularised flaps. When large areas of resections are performed, the use of sternal prosthesis could be considered to ensure chest wall stability and cosmesis.
We report an individualised three-dimensional (3D)-printed high-density polyethylene (HDPE) sternum implantation in a patient with a 10 cm chest wall defect.
Chest wall reconstruction was uncomplicated and the patient tolerated the procedure well without cardiorespiratory compromise. Postoperatively, the wound healed well and the chest wall remained stable at outpatient clinic follow-up.
Three-dimensional-printed HDPE prosthesis offers an alternative implant option for closing large chest wall defects for eroded sternum after cure of mediastinitis.
胸骨切开后纵隔炎（PSM）是正中胸骨切开术的严重并发症。它与高死亡率相关。循证管理建议清创后使用带血管的皮瓣关闭。当进行大面积切除时，可考虑使用胸骨假体以确保胸壁稳定性和美观。
我们报告了在一名 10 厘米胸壁缺损的患者中使用个体化三维（3D）打印高密度聚乙烯（HDPE）胸骨植入的情况。
胸壁重建顺利，患者耐受良好，无心肺功能障碍。术后，伤口愈合良好，在门诊随访时胸壁保持稳定。
3D 打印高密度聚乙烯假体为治疗纵隔炎后侵蚀性胸骨的大胸壁缺损的闭合提供了另一种植入物选择。
