Abstract
3D-Printed Personalized Titanium Implant Design,Manufacturing and Verification for Bone Tumor Surgery of Forearm
Highlights
The treatment of primary malignant bone tumors has progressed over decades and this has led to the success of limb salvage procedures in approximately 85% of cases [1-9]
This study aims to demonstrate the whole process of 3D printing titanium tumor implants including implant design, manufacturing, and performance evaluation
Throughout this study, we reconstruct 3D model using CT data of forearm tumor of the patient and simulated virtual surgery to set a safe margins of resection tumor
Summary
The treatment of primary malignant bone tumors has progressed over decades and this has led to the success of limb salvage procedures in approximately 85% of cases [1-9]. As far as the limb salvage procedures are concerned, an endoprosthetic replacement has been regarded as the standard reconstruction technique after wide excision for bone sarcomas in musculoskeletal oncology centers [10]. As for reconstruction of uncommon bones, a custom- made prosthesis was one of available surgical options, but the problem was that it took a long time to fabricate and it was expensive. The 3D printing implant is applicable to any bones of all sites. It requires relatively short fabrication time and is cheaper than a conventional custom-made implant. The manufacturing of specific 3D implant is composed of five stages; a) First, obtaining the 3D model of the patient by receiving the DICOM files (DICOM, Digital Imaging and Communications in Medicine) from the hospital
