3D-Printed Personalized Titanium Implant Design,Manufacturing and Verification for Bone Tumor Surgery of Forearm
Journal Title: Biomedical Journal of Scientific & Technical Research (BJSTR) - Year 2018, Vol 10, Issue 3
Abstract
The 3D printing implants are currently being used to reconstruct various parts of the bone tumor area other than maxillofacial surgery area. Thanks to 3D printing implants, patients can remain their anatomic function of bone through reconstruction surgery, which was impossible before since patients became handicapped. The segmental prosthesis of the long bone needs a special design for fixation with normal bone as well as maintaining the joints and mechanical stability. In this preliminary report one can find procedures of test surgery on volunteer patient which include design, manufacturing process, inspection, and mechanical test procedures. The patient underwent reconstruction surgery using 3D printing metal implant for both forearm bones. By using 3D printing metal prosthesis for reconstruction of the bone defect, surgeons were able to shorten duration of the surgery and maintained the anatomical reconstruction for the all bones of patient's body.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]. However, commercially available modular type of the prosthesis is supplied only for commonly used replacements such as the femur, tibia and humerus. 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. Frankly, the 3D printing implant is applicable to any bones of all sites. Furthermore, 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. b) Second, designing the implant and cutting guide. c) Third, printing implant and cutting guide using each 3D printer. d) Fourth, post-processing process. e) Fifth, processing implant's inspection and cleaning.This study aims to demonstrate the whole process of 3D printing titanium tumor implants including implant design, manufacturing, and performance evaluation. In order to deliver the outcomes, our team would like to report a representative case of reconstructive surgery with 3D printing prosthesis for both forearm bone while preserving the adjacent joints of the forearm (Figure 1).
