3D Printed Implants for the Defect Reconstruction in Patients With Chest Wall Tumors

Summary

A patient with a tumor lesion of the chest wall undergoes CT scan with a step width of less than 1 mm, then engineers design an individual model to replace the defect. Using a 3D printer, a model is made based on titanium alloy powder. Preoperative preparation takes an average of 14-21 days. The next stage is surgical treatment in the amount of resection of the chest wall with plastic defect with an individual titanium implant. In some cases, the titanium framework is separated from the pleural cavity by a polytetrafluoroethylene plate in order to seal and prevent the development of pulmonary hernias. The advantages of titanium individual prostheses include accurate matching of the implant to the size and characteristics of the defect, individual modeling allows you to repeat the anatomical features of the patient. This method helps to recreate the original shape of the chest, and most importantly, symmetrical, relatively healthy half. With the help of titanium, individualized prostheses are made based on 3D modeling, which will reduce the incidence of complications, accelerate rehabilitation and improve the quality of life of patients with tumor lesions of the chest wall. The postoperative period takes 15-30 days.
