Three-dimensional printed polyether-ether-ketone implant for extensive chest wall reconstruction: A case report.

Three-dimensional printed (3DP) implant offers a valid option with perfect anatomic fitting in individual and skeletal reconstruction of the chest wall. Herein, we present the case of a patient with a large chest wall tumor, where an extensive chest wall defect was repaired using 3DP polyether-ether-ketone (PEEK) implants. Surgical treatment planning was performed according to the computed tomography (CT) images in DICOM format. A 3DP implant was then design and fabricated. A wide excision of the chest wall tumor was performed, including the entire sternum, 2-6 costal cartilage and ribs, and parietal pleura. Furthermore, a skeletal reconstruction was carried out using a 3DP PEEK implant. The patient recovered well without surgical complications or tumor recurrence in the following year. In general, 3DP PEEK implant is an appropriate alternative for chest wall reconstruction. KEY POINTS: SIGNIFICANT FINDINGS OF THE STUDY: Skeletal reconstruction after wide excision of the chest wall remains a challenging problem for clinicians. WHAT THIS STUDY ADDS: 3DP PEEK implant is an appropriate alternative for chest wall reconstruction.
